It is quite possible.听

Out there, there will be no dearth of scintillating toppers with a grand 91热爆 Quant score. But the question that remains is: how did they manage to achieve it? Do you think there is some magic here? What is the sleight of hand they employ that you don鈥檛?

Imagine a novice typing something on a keyboard using two fingers and compare him with a professional typist whose fingers literally fly over the keyboard. Picture the grace and fluency that a professional has. By constantly honing his skills in typing, he has mastered the art of using the right fingers for pressing the right keys. And, his confidence in the job makes him look near-perfect. Much in contrast to the novice who would take some minutes just to type his/her own name.

For all we know, the novice works harder to type with two fingers than the professional. But how far do his results take him? 

Now, we have all heard of the 鈥減ractice, practice, practice鈥� rhetoric. 

Yes, there is practice and much more!

Being Good vs. Scoring 骋辞辞诲听

So you are good at Mathematics?听

That’s great, but does it really help you in improving your 91热爆 Quant score?

It鈥檚 not easy to get the 91热爆 Quant score of 160+. It鈥檚 an online adaptive exam that 鈥榓dapts鈥� to your level of competency. That is, the successive sections get harder or easier based on the performance of your previous section. You do not get the leisure of pondering over a problem since you would be expected to solve approximately 20 questions in 35 min. Spending a long time on a tough question will make you run the risk of losing out on an easier question later on.

So being good at Quant will not suffice, unless you are exceptionally good.

Scoring good in the 91热爆 Quant section is what matters, and that would take good 91热爆 Quant preparation.听听

The Challenge of 91热爆

91热爆 is not just a test of competency. It tests applicants on their time management skills and adaptation skills to face challenging scenarios. So solving a problem is not good enough. Solving it fast is what would give you an edge over the other applicants.

That edge might push you into the league of 40% of the test-takers with 91热爆 Quant score above 160. 

But how about getting into the 23% league of elitists with 91热爆 Quant score 162鈥�166? Surely immaculate time-management skill is not the only ace up their sleeve.

Let鈥檚 explore a bit more.

For starters, do you know what the four sections are in 91热爆 Quant section?

Preparation: Knowing what to expect.

The only way to save yourself from not falling into despair in the middle of preparation is by knowing the type of questions that you can expect in the 91热爆 exam. A proper scheme of plans and strategies will definitely be the X factor to help you push the borders.

The challenge starts with this topic:

Arithmetic: 

The arithmetic section would involve questions on properties and types of integers, arithmetic operations, exponents, and roots. Concepts on estimation, percent ratio, rate, absolute value, number line, decimal representation, and sequence of numbers would be your hosts in the 91热爆 exam.

Algebra:

Algebra topics would include operations with exponents, factoring and simplifying algebraic expressions, relations, functions, equations, and inequalities. You would be expected to solve problems on linear and quadratic equations and inequalities. Also, there would be problems with simultaneous equations and inequalities.

Geometry:

Geometry for conceptual thinkers would include challenges from parallel and perpendicular lines, circles, triangles, quadrilaterals, and other polygons. Congruent and similar figures, three-dimensional figures, area, perimeter, and volume would be in the list. And lastly, problems from the Pythagorean theorem and angle measurement in degrees.

Data Analysis:

Data analysis ranges from basic descriptive statistics such as mean, median, mode, range, standard deviation, interquartile range quartiles, and percentiles. This section would also ask you to approach problems from interpretations of data in tables and graphs, elementary probability, permutations, and Venn diagrams.

Now that you are familiar with the problems, let鈥檚 look at the solutions. Let’s begin by looking at what you can do about them, optimally.

 What 160+ scorers do:  Closing the gap

There is no insurmountable wall between you and a good 91热爆 Quant score of 160+. It is not rocket science. There is no magic and certainly no wonders. When you walk into the exam room on the test day, you know you鈥檇 have nothing but a 91热爆 Quant score above 160 and the results would just reflect your confidence. Even if you have a little doubt about things going wrong, then things would go wrong. So start now, start strong, and improve your 91热爆 Quant score.

Start with the Basics

We might have been proficient with the basics of math in our high school. But time turns and makes everyone rusty when we don’t practice them much. Basics of arithmetic are often overlooked by a lot of people who try to work on finesse without getting the foundation right. Such students can find it very challenging to improve Applied Math and Data Interpretation since they hit a roadblock. Because, for these topics, flawless conceptual knowledge in basic arithmetic is a prerequisite.

Skipping Steps

Deviating from the established procedures can lead to a disaster. The small steps that are skipped in the calculations to save time come back as low scores, often due to silly mistakes and a bag full of regrets. Avoid these to improve your 91热爆 Quant score.

The Lure

Try this question:

Question: Given 3a is an even number

Quantity A: a 

Quantity B: 2a

Which of the following options is correct:

1. Quantity A is greater

2. Quantity B is greater

3. The two quantities are equal

4. The relationship cannot be determined from the information given

Did you go for the 2nd answer?

Congrats! You just got baited and your temptation to quickly mark a right answer has cost you the perfect 91热爆 Quant score.

Getting lured to the wrong options in multiple-choice questions can also be an indirect result of the former. Options are designed to replicate wrong answers which are often the products of the most common mistakes students make. 

Inadequate practice essentially breeds low confidence. With low confidence comes anxiety, fear, and low motivation. You cannot expect to run on the tracks of this race with such weights attached to your back. Students with low confidence and low motivation end up wasting a lot of time. In the end, anxiety ruins the entire scenario. 

(P.S. The explanation and the right answer is posted at the bottom of the page. Find out where you went wrong. Scroll down!)

This tip Never gets old!

Being prompt on plans and being regular with practice is the tried and tested solution to this problem. Not only does it bring out the weaknesses that you need to polish, but also slowly settles you into the scenario of time-bound testing. Challenge yourself constantly and ensure that you achieve accuracy all the time. Try to bring up the dropping curves of your performance graph to a consistent straight line. 160+ 91热爆 Quant scorers do well consistently in all spheres of the pattern. Overlooking the weaknesses you have can leave serious dents in your 91热爆 Quant preparation that you might find harder to mend in the later stages.

Ease your pressure

Leave no stone unturned when it comes to 91热爆 style mocks. Buck yourself up to reduce pressure, by solving under the clock. After all, in the examination, you get no more than 1:20 min to solve a single question. You could be running short of time towards the end if you are not alert to the time factor from the beginning. The more number of practice tests you take, the more accustomed you get to face all these problems.

Problematic DI

Speaking of question lists, it鈥檚 advised to attempt Data Interpretation questions at the end. DI is known to baffle students with tricky questions. The dominating panic of getting a question wrong after spending a minute or two on it can adversely affect the chances of getting the other questions right. 

Don鈥檛 let the easy correct answers suffer.

Exam time follies

Lastly, organize your rough sheet/scratch paper. Number the calculations and make proper and efficient use of the rough space. 

When the clock鈥檚 ticking, it can be very hard to focus on the organization.

The last thing that you would want to happen in your rough sheet is the 鈥�6鈥� of Q.5 mixing up with the 鈥�66鈥� of Q.6. 

How confusing will that mess be?

But, what are the solutions for all these problems?

No Sermons : You need Proper Advice

It is true there is information everywhere today. But there is always a trade-off which, in this case, is quantity over quality. The aspect of authenticity has been drowning in the depths of opinions and sermons since the time the Internet was born. Finding relevant information suddenly became very hard. Compilation of tips for scoring 160+ was found wanting when a lot of information was thrown about without valuable insights from a teacher. 

It took some time to track down one such SFA (Student Facilitator Analyst) responsible for the success stories of many students. It took even more time to insist on a one-on-one Q&A with him but he eventually agreed. We had a discussion and here is the crux of it: 

Q. What percent of students have a 91热爆 Quant score above 160?

Around 40% of people who take the 91热爆 exam have a 91热爆 Quant score above 160. The numbers go higher during Jun鈥揓ul. Since people with good insights about their 91热爆 prep give the exam during this time, and they start preparing with us months earlier. They know about their weaknesses and have worked a lot to rectify them. So their results are obviously better.

Q. What part of the Quant syllabus do you think most students are weak in?

By far, Probability Distribution questions seem challenging to most of our  students. Their weaknesses become evident in the revision tests and the 91热爆 style Quant tests they take. So, it does not come as a surprise when we find that their scores dip in PD and DI in the practice sessions. 

Q. What part of the 91热爆 exam do you think students lose most of their marks in?

So there are questions that have more than one answer. Students find them confusing and they make a lot of mistakes. Also there are numeric entry questions which require students to enter a precise numerical value. Since these types of questions do not have options and require a high degree of precision from the student鈥檚 side, a lot of mistakes are committed. Also, topics such as Applied Mathematics and Venn diagrams trouble students the most. That is where they lose their 91热爆 Quant scores. If they practice adequately and focus on their time-based accuracy, I鈥檓 sure they can overcome this.

Q. What do you suggest to the people who aspire to break the 160 barrier?

We can gauge the competency level of the student when he joins us and gives the diagnostic test and review tests. The stats speak for the student. We can estimate the student鈥檚 91热爆 Quant score over blurry lines. Sometimes, we are happily surprised. But more or less, the advice stays the same 鈥� whether it is a 160 or 150 student.

First, conceptual knowledge. Without that, aggressively preparing for other parts can be ineffective, since sooner or later we have to come back to the basics again.

Second, application of concepts. Learning concepts is what we can help our students with, but the application has to be taken care of by the students by relentless practice under time constraints. 

Third would be accuracy. Time management has always been a core part of 91热爆 preparation. But time management cannot come in lieu of accuracy. Accuracy is useless without time management, as is time management is without accuracy. Getting an answer right is not a big deal. Getting it right under constraints of time and overwhelming exam pressure can be difficult. For us, that is the concept of accuracy.

Q. Do you think that 91热爆, being an online test, hampers the ability of the student to score well?

Yes, of course. Not many of us are acquainted to the online platform of education. And 91热爆 is no normal test. For one, applicants pay a lot to sit for the exam, and on top of it their dream of achieving big depends on their success in this test. Students complain upfront about the inconvenience of taking the test online. Something as simple as turning pages to find the review questions by clicking buttons also becomes a point of concern. While all of this might sound very easy even to a seasoned user of computers, under the pressure of a ticking clock small things like this can become a big problem. Also the places where you are supposed to use a calculator that is provided by fighting the urge to calculate manually, is something that a student must master. So being comfortable with the online platform is a big issue. Preparing online will help.

Q. What is the ideal number of mock tests you would recommend before taking up the final exam?

The more the better! About 8 to 9 mock tests should do the trick for Quant. Priority should be to get used to the conditions. And, maintaining accuracy without worrying about time.

Q. What score do you think is a good indicator of 160+ 91热爆 Quant score in our 91热爆 Quant test?

Ideally 30, but someone is yet to achieve that. It is seen that people who manage 28 or 29 in our review tests consistently, go on to secure a 91热爆 Quant score of about 160 and above.

He went on to show me some stats from the Learning Tracker. And it indeed was congruent to what he said.听听

Here are the stats of 91热爆 students and their accuracy on questions of different difficulty level. Have a look at their 91热爆 Learning Tracker Stats :听

Fig 1.2: Performance Accuracy on Easy, Medium, and Hard Questions

This graph shows scoring patterns of students on difficulty levels easy, medium, and hard questions of 91热爆. 166鈥�170 91热爆 Quant scorers had a scoring accuracy of nearly 56.30% on difficult questions and 85.51% scoring accuracy on easy questions. Have a look at the yellow pillars and realize how they stand tall against the others.

Summarizing: What is your take away?

But before that as promised,

The explanation of the questions shown above awaits you!

We know that Odd 脳 Even = Even.听

For 3a to be even, a must be an even number

a = 0, 2, 4, 6, 8, ..

For a = 0, the two quantities are equal

For a = 2, 4, 6 quantity B is greater.

Therefore, the relationship cannot be determined from the information given.

If you had chosen option b, then you might not have taken a = 0. Remember, 0 is also an even number.听

No doubt that we all start off by typing with two fingers. But some found the time to practice the right way. They stumbled countless number of times but their persistence to do it right took them places. They were not adamant and they learned from their mistakes. Their methods were simple but organized. And as tempting as it was for them to deviate and cut corners, they did not. When the chips were down, it was their self-confidence that motivated them to perform better.

Perhaps, that is why they type so flawlessly today.

Perhaps, that is why they scored 160+ in 91热爆 Quant.

Do you think you can do it?

Absolutely, you can!

Happy Learning!

Introduction to 91热爆 Probability

The Quants section of 91热爆 assesses you across four broad areas- arithmetic, algebra, geometry, and data analysis. Probability is one of the concepts tested in the data analysis section. However, Probability is just a small part of data analysis and you may expect hardly two to three questions on probability.

Now, you might be asking why to study probability if it forms such an insignificant part of 91热爆 Quants? Well, if you are aiming for a high score in the quantitative section and have already mastered the algebra, arithmetic, and geometry; then two or three questions can make a world of difference in your scores. It is therefore important that you familiarize yourself with the basics of probability thereby raising your chances for a higher and a better 91热爆 Quants score.

Download our eBOOK on “5 Techniques to score a perfect 170 in 91热爆 Quant“

Probability questions can take on many different forms such as multiple choice questions, quantitative comparison, and numeric entry. In case of multiple choice questions, you will be asked to select only one answer from a list of five choices. Quantitative comparison questions consist of two quantities, let鈥檚 say A and B, which are accompanied by a description. Your task is to compare the quantities and select one of the four possible choices. Numeric entry questions, as the name suggests, ask you to enter your answer either as an integer or as a decimal in an answer box or enter a fraction in two separate boxes.

Concepts tested in 91热爆 Probability

Now that you have a fair idea about the number and kind of questions to expect, let us have a look at the concepts tested by these probability questions. All 91热爆 probability questions will test your knowledge of two basic concepts- simple probability and permutation and combination.

Simple probability:

Probability is a way to describe uncertainty and the possible outcomes of an experiment using numbers. Simple probability determines the likelihood that an event will happen. Let us look at an example to understand simple probability better.

When we perform an experiment, then the set of all the possible outcomes is called the sample space (S). When we roll a die, the possible outcomes are 1, 2, 3, 4, 5, and 6. Here, in our example of rolling a die the sample space is-

S = {1, 2, 3, 4, 5, 6}

Any subset of the sample space is called an event. So, let鈥檚 say 鈥渞olling an even number鈥� is an event which corresponds to the outcome of {2, 4, 6}. Now, the probability of rolling an even number is the number of outcomes that constitute the event divided by the total number of possible outcomes. We call the outcomes in an event its 鈥榝avourable outcomes鈥�. So, the probability of an event is determined using the following formula-

Probability = Favourable number of events / total number of events

or, 听听听听听P(E) =n(E) /听n(S)

Therefore, the probability of getting an even number when we roll a die is-

Probability of getting an even number = {2,4,6} /听{1,2,3,4,5,6}

= 3/6 听听

= 1/2 听听

Thus, the probability of getting an even number while rolling a die is half. Or in other words, the probability of getting an even number when we roll a die is fifty percent.

Permutation and combination:

Apart from simple probability, the 91热爆 probability section also tests your knowledge of permutation and combinations. In very simple words, permutation refers to sequences and combination refers to groups. In a sequence order is important. Therefore, permutations are sequences where order is important, whereas in case of combinations, the order is not important. Let us understand both these concepts with the help of an example.

Consider the following question:-

In how many different ways can five people sit in a row?

In this question, we have to arrange five people in a sequence. However, the order is important in solving this problem. Now, for the first spot in the row, we have five people to choose from. As we go down the line, the number of people we have to choose from will decrease by one. Therefore, we have 5 x 4 x 3 x 2 x 1 = 120 ways in which five people can sit in a row.

Now, consider this question:-

Steven drew 13 portraits for his art project. He wants to choose 8 of them for his studio art final. How many different groups of photos are possible?

If you observe carefully, this question asks about groups and not the order in which the portraits will be chosen. Therefore, this is a combination problem. Therefore, using the formula-

nCk = n! /听k! * (n–k)!

= 13! /听8! * (13–8)!

= 1287 different groups

Tips to master 91热爆 Probability questions

Tip 1- Confirm that the question is on probability:

In 91热爆 questions don鈥檛 come labeled or tagged as arithmetic or probability. It is therefore important to determine whether the problem involves probability or not. So, look for the word 鈥榩robability鈥� in the questions. If you cannot find the word 鈥榩robability鈥� embedded in the question description then look for other important and related key terms such as- event, outcome, random selection.

Consider the following example-

1) A fair dice is tossed. Event A is defined as getting a prime number and event B is defined as getting an even number. Which one of the following is/ are true?

(i) P(B)= 1/2

(ii) P(A n B)= 0

(iii) P(A) + P(B)= 1

(iv) P(A n B)= 1/6

(v) P(A)= 4/6

Notice in this example question that the word probability has not been used. But as you can observe the word event appears in the question. This means that the question involves probability.

Tip 2- Memorize the formulas:

If you want to have a good Quants score then memorizing the key formulas in probability is important. You should not be wasting time trying to figure out what the formula was as you don鈥檛 get a lot of time to solve the questions. Our experience with 91热爆 aspirants shows that top scorers actually spend more time learning formulas and concepts rather than practicing sums.

These are some of the important probability formulas you can memorize and keep in handy-

The probability of an event = Favourable number of event number of total outcomes

Odds in favor of an event = Number of favorable outcomesNumber of total outcomes

Odds against an event = Number of unfavorable outcomesNumber of total outcomes

Tip 3- Practice a lot:

There is no shortcut to success. And that is true even for 91热爆 Quants. If you are dreaming of higher Quants score, your dream will come true with thorough practice. Data shows that difficulty level of questions on probability is usually medium to high. So, make sure that you practice 91热爆 questions which are a little tough. You must practice advanced 91热爆 questions of level 4 and level 5.

In order to secure a higher percentile in 91热爆 Quants, it is important that you gain enough understanding of probability concepts. In fact, achieving a perfect 170 in Quants is not a very difficult task. What you need is some advice and guidance regarding how to prepare and avoid some common mistakes that 91热爆 test takers often make. You can check out our video on Quant Shortcuts! (Probability)

We hope this article provided you with smart ways to crack 91热爆 Probability questions. All the best!

Scoring a perfect 170 in Quant is definitely an achievable target, particularly for engineers.

But, silly mistakes and exam nerves almost always get the better of most of us.

While it can be extremely frustrating, it is a serious problem that prevents many students from actually achieving their true potential.

One such student was Somya Bajaj.

听

With her sights set on Ivy League Universities, she was aiming for a 325+ score.

In Nov 2015, Somya took up the task of preparing for 91热爆 and spent 3 months of dedicated attention to mastering each of the 91热爆 topics.

听

Come exam day, Somya was left disappointed as she stared at an unsatisfactory 310 on the screen.

Fast forward to a year later, in Sep 2016, Somya decided to plunge into her 91热爆 preparation again.

With two personal trainers, she realized where she was making mistakes.

鈥淔or example, after analyzing the time spent on each of the test questions, her clicks, and her answer choices in her online practice, her Quant trainer found out that her problem was not with difficult questions, in particular, but with lengthy questions that required her to read through details carefully.”

Armed with a constructive feedback like this, Somya consciously worked on her weak areas and gave her 91热爆 again in Nov 2016.

This time, Somya walked out with a massive 23-point score boost and a 333 in 91热爆.

What Expert Tips Helped Somya Overcome Silly Mistakes in Quant

听

#1: Befriend Time

There are 20 questions and 35 minutes, per Quant section. This means that you shouldn鈥檛 spend more than 1.5 minutes per question.

To achieve this, if you are using a watch, then stop it right away. Practice with a timer, preferably online, so that you recreate the actual 91热爆 atmosphere as much as possible.

91热爆 Pro Tip: If a solution doesn鈥檛 present itself within the first 30 seconds of seeing the question, just mark it for verification and move on. Come back to it after answering other questions confidently!

听

#2: Switch It

Our Quant SFAs (Personal Trainers) here at 91热爆 say, 鈥淪ubstitute 0 and 1 wherever you can, particularly for Quantitative Comparison questions.鈥�

This saves you a large amount of time, as you will be able to answer the questions within seconds.

For example, consider this question:

听

听

Rather than using algebraic methods to solve this question, simply substitute 0 in place of x.

A = 3x + 2 = 3(0) + 2 = 2

B = 3(x + 2) = 3(0 + 2) = 6

Therefore, option B is the correct answer!

And look at the time! Not even 10 seconds.

• Algebra
• Arithmetic
• Geometry
• Applied Mathematics
• Data Interpretation

For most engineers, after doing more complex mathematics for four years, questions based on the concepts of algebra or arithmetic are easier to tackle compared to Data Interpretation or Geometry. This is simply because they are out of practice.

But why should you focus on Data Interpretation particularly?

If you aim to hit a 160+ in Quant, then is important to spend enough time learning and practicing Data Interpretation because a minimum of 4 or 5 questions can be expected in each Quant section. This means that DI carries a 20% weightage in the Quant section.

Makes it pretty important to get right to a high score, don鈥檛 you think?

Structure of a 91热爆 Data Interpretation Question:

In a DI question, you will face one form of pictorial data such as a bar chart (either horizontal or vertical), pie charts, line graphs or tables, followed by 3 or 4 questions on the same. The question types could be multiple-choice or numeric entry types.

Throughout this post, you鈥檒l see all the different types of examples!

For example,

The line graph shows the ratio of imports by a company to the number of exports from that company over the period 2000鈥�2006.

Q. In which year, was the imports to the exports of the company greater than 0.3 and less than 1.1?

Indicate all such years.

Choices:

1. 2000
2. 2001
3. 2002
4. 2003
5. 2004
6. 2005
7. 2006

Ans: The correct answers are options A, B, C, and F

From the graph,

Ratio of value of imports to exports in 2000 = 0.65

In 2001, ratio of value of imports to exports = 0.85

In 2002, ratio of value of imports to exports 听= 0.35

In 2003, ratio of value of imports to exports = 1.25

In 2004, ratio of value of imports to exports = 1.4

In 2005, ratio of value of imports to exports = 0.95

In 2006, ratio of value of imports to exports = 1.55

The correct answers are 听A, B, C, and F

Some common 91热爆 Data Interpretation mistakes to look out for:

1. Misinterpreting data due to impatience/over-confidence
2. Time management
3. Lack of practice
4. Overlooking details

Since there are 20 questions in each Quant section and you have only 35 minutes per section, you cannot spend more than 2 minutes on any of the questions.

So, within 2 minutes you need to assimilate data, interpret it correctly, and answer questions that follow. This can be quite a task if you are not familiar with reading data.

So, how do you pick out the relevant information and do it for 2 minutes?

听How to Approach a 91热爆 Data Interpretation Question:

First, don鈥檛 be alarmed when you see data that apparently seems complicated. There is a method to the madness.

There are important techniques that you can follow that will help you figure out the right answers.

#Tip 1: Look for tell-tale signs:

Your graph may look complicated but there are some key points that you should note down as soon as you see a graph, like the axes of the graph, the units of measurement, and the title of the graph. It is important to pay attention to the title because you will be able to pick out crucial facts like what the data represents.

For example,

Annual Percent Change in the Dollar Amount of Sales at Five Retail Stores from 2006 to 2008

Q. At Store P, if the dollar amount of sales was $800,000 for 2006, what was the dollar amount of sales for 2008?

1. $727,200
2. $792,000
3. $800,000
4. $880,000
5. $968,000

Ans: The correct answer is Option B, $792,000.

Explanation from our SFAs:

Since it is mentioned that the sales of Store P was $800,000 in 2006, we can use that to calculate the听respective rise in percentages for 2007 and 2008.

According to the figure, the percentage increase for 2007 is 10%. So, we will calculate it as 110% of the base amount, which is, 110% of $800,000 = $880,000.

Similarly for 2008, the percentage decrease is 10%. The calculation is 90% of $880,000 = $792,000.

91热爆 Pro Tip: Always ensure you check the base amounts before doing calculations like these. A percentage increase of 10% in 2007 followed by a percentage decrease in 2008 does not mean the answer is the same as the initial amount because the base amounts for 2007 and 2008 are different.

Thus, 鈥�Annual percent change in the dollar amount of sales at five retail stores from 2006 to 2008鈥� tells us that the data represents 鈥減ercent change鈥� rather than absolute percentages.

#Tip 2:听The Art of Being Approximately Accurate:

The 91热爆 is meant to test your presence of mind apart from your reasoning skills. This means that you will encounter some challenging numbers and calculations. Before you jump to the online calculator and start crunching numbers, wait! Round up decimals and approximate to the nearest whole numbers so that you know the ballpark figure. For example, 27% of 153,000 could be rounded off to 25% of 150,000 so that you can eliminate far-fetched options.

91热爆 Pro Tip: Beware and use this sparingly. If the answer choices are pretty close to one another, it is best to skip this step and directly calculate your answer. If your range includes two options then it makes it necessary to actually calculate the answer causing you to waste more time.

#Tip 3:听Say What?

I cannot emphasize this enough because this is one of the common reasons behind students scoring a 165+ but not a 170. Read the question carefully and understand clearly what you鈥檝e been asked to answer. Many times, the answer choices have two right answers but to two different questions. If you haven鈥檛 read the question correctly because you were in a time crunch, you will choose the other answer and hence lose out.

For example,

Q. If 3000 copies of a book are published and the paper cost on them amounts to $ 9000, what should be the selling price of a book so that the publisher can earn a profit of 25%?

Choices:

1. $ 3.4
2. $ 12.5
3. $ 37, 500
4. $ 10
5. $ 2.5

Ans: The correct answer is Option B, $12.5.

Explanation from our SFAs:

Let the SP of 3000 books be $ X.

To earn a profit of 25%, SP = CP + 25% of CP = 125% of CP

From the given pie-chart,

paper cost = 30% of CP

$ 9000 = 30/100 * CP

CP = 9000 脳 100 / 30 = $ 30,000

SP = 125% of $ 30,000

= 125 / 100 脳 30,000

= $ 37,500

Therefore, SP of one book = 37500 / 3000 = $ 12.5

For a pie-chart question, bear in mind that the whole pie is split into parts of a whole either using percentages or degrees.

The following conversion can be used to calculate the value of the sector based on what is given in the pie-chart.

Value of the sector = (Percentage / 100) * Total value

Value of the sector = (Central angle of the sector / 360)* Total value

For this question, after a quick scan, if you assumed the 鈥減aper cost鈥� to be 108%, then you would choose the first option i.e., $ 3.4, which is incorrect.

#Tip 4:听Develop an Eagle Eye for Charts:

Interpreting data quickly is a skill that comes with practice. Make sure you practice different kinds of charts and questions. This will help you overcome most of the problems mentioned above. And since DI is a sure-shot question, it pays to perfect your techniques.

91热爆 Pro Tip: Practice questions where there is more than one type of chart and you have to correlate data. This will help you understand the relationships between different types of data and the variables connecting them. This helps you understand data analysis as a whole.

For example,听Profit and Turnover of Company PQR Over the Period 2004-2008

Q. If the turnover in the year 2008 is decreased by听15% and the ratio of the profit and operating cost remains the same, what will be the profit in the year 2008?

Note: Turnover – Operating Cost = Profit

1. 0.48
2. 0.408
3. 1.28
4. 1.088

Ans: 听The correct answer is Option B, 0.408.

Explanation from our SFAs:

Given data: Total turnover, Total profit, Ratio of profit & Operating cost are the same & 听Turnover – Operating cost = Profit

Total profit = Profit in (2004 + 2005 + 2006 + 2007 + 2008)

$1.44 million = $0.36 million + $0.288 million + $ 0.192 million + $0.12 million + Profit in 2008

Therefore, profit in 2008 [P(2008)] = $ 0.48 million ———-> (1)

But, Turnover in 2008 = 1.76
Operation cost of year 2008 [OC(2008)] = Turnover 鈥� Profit = 1.76 鈥� 0.48 = 1.28 ——> (2)

Therefore, P(2008) / OC(2008) = 0.48 / 1.28 ———–> (3)

Given that, turnover in the year 2008 is decreased by 15%.

So, the New turnover = 1.76 鈥� (15% * 1.76) = 1.76 * 0.85 = 1.496 —–> (4)

Now, if the new profit and operating cost are P1 & OC1 respectively, then according to the question,

P(2008) / OC(2008) = P1 / OC1

Therefore, P(2008) / OC(2008) = P1 / OC1 = 0.48 / 1.28

Since, we have to calculate profit, OC1 = P1 * (1.28 / 0.48) = P1 * 2.67 —–> (5)

Operating cost = Turnover 鈥� Profit

Therefore, New turnover = P1 + OC1

1.496 = P1 + P1*2.67 = P1 * 3.67

Therefore, P1 = 1.496/3.67 = 0.408

#Tip 5: Befriend the Pen & Paper:

When you are practicing DI questions, always use a pen and paper to jot down the important points mentioned in the question as well as minimum and maximum values, reference values based on which the graph is drawn, etc. With time, you will become accustomed to picking out these values as soon as you see a graph.!

To summarize, these are some of the points to remember:

1. Spend only 15 to 30 seconds analyzing the graph and jotting down key information. Don鈥檛 spend more than 2 minutes per question.
2. The answer is literally staring at you in the face in the graph. So, don鈥檛 feel disheartened. Mark it for verification and get back to it, if you are unsure of the answer.
3. There is no negative marking in 91热爆. Approximate and make an intelligent guess, but make sure you answer. You may be lucky!
4. The devil is in the details. Make sure you pay attention to the axes, the units asked the question, concepts used like percent changes or sector to percentage conversion etc.
5. Try to practice as many questions as you can so that you feel, 鈥淥h, I鈥檝e seen this kind of question before,鈥� during the exam!

The post Top 5 tips to crack 91热爆 Data Interpretation Questions appeared first on 91热爆 Blog.

Academically speaking, I鈥檓 a pretty good student. I always make sure my scores are above 80. But never have I ever dreamt of scoring a perfect score in Math.  This is probably because of the mental conditioning that a perfect Math score MIGHT not be possible because it is annoyingly easy to make silly mistakes. We carry this impression all through our lives and believe that getting a cent percent in Maths is impossible.

Do you also feel the same way?

I was of the same school of thought until I spoke to some of our toppers and discovered their secret formula to a flawless 170.

What if I told you,

YOU could score a perfect 170 in 91热爆 Quant? You wouldn鈥檛 believe me. Of course.

Would you believe me if I told you HOW? Maybe? Alright.

Just to give you a quick recap, the 91热爆 Quantitative Reasoning section includes four broad topics,

• Algebra
• Arithmetic
• Geometry
• Data Interpretation
  

91热爆 Math is a little different from high school math, not in terms of the concepts (which are pretty similar), but more in terms of their application. It tests your ability to interpret given data correctly and critically reason rather than just test your knowledge on formulae and concepts.

Common Mistakes YOU need to avoid in the 91热爆 Quantitative Questions

Calculation mistakes:

Silly mistakes fall under this category. This is the main reason why most people fall short of the perfect score. You make these mistakes when you calculate something that is not required or not asked for because you didn鈥檛 understand the question correctly or you didn鈥檛 follow the method properly.

For example, if the given question asks you to calculate x2 but you mark the answer as soon as you calculate the value of x.

Conceptual Mistakes:  

These are the kind of mistakes that occur when you aren鈥檛 clear with your concepts. It is commonly seen in students when they attempt questions on  Geometry because they have trouble visualizing an object in a three-dimensional space.

Alright, now that you know what 91热爆 Quant contains and the mistakes you should be aware of, let鈥檚 look at some of the techniques we can utilize to overcome this, shall we?

TECHNIQUE #1: Befriend time

Since there are 20 questions in one 91热爆 Quantitative Reasoning section and 35 minutes to answer, logically it follows that you can spend almost 2 minutes per question if you want to answer all of them.

I know that 2 minutes sounds like an awfully short amount of time for solving full-fledged 91热爆 math questions, but trust me, it is just sufficient if you are thorough with the concepts.

In fact, try this question and time yourself.

Topic: Arithmetic
Difficulty: Level: 2

Q. Evaluate: 40 鈥� (2*12+15%5) +14*4%8

How much time did YOU take to arrive at the answer?

91热爆 Pro Tip:听 For questions of a difficulty level of 4 and 5, you can spend up to 2 minutes on it. If you are taking longer than 2 minutes, take an intelligent guess, select a choice and mark it for verification so that you can come back to it later.

TECHNIQUE #2: Beware of booby traps

Most of the answer choices for questions include those options that you would mark if you make some of the common silly mistakes. DON鈥橳 fall prey to them. They are designed to test how alert you are while giving the test.

Calculating x and marking it as an answer while the question asks for x2 is a perfect example because one of the answer choices will carry the value of x as an option.  

Try this example;

Topic: Algebra
Difficulty Level: 1

Q. If 虫虏 + 6x = 鈥�9, how many values of x are possible?

• none
• one
• two
• three
• infinitely many

How much time did YOU take to arrive at the answer?

The answer is option B: one.

虫虏 + 6x + 9 = 0
(虫+3)虏  = 0
Therefore, x = -3

The two roots are equal and identical, but the 鈥渧alue鈥� of x is only one i.e -3.

But after factorizing, you can see that the two roots are identical and hence only one value of x is possible. The question here asks for 鈥渧alues鈥� and not 鈥渞oots鈥�.

TECHNIQUE #3: Substitute 0 and 1 wherever you can

You can save massive amounts of time by just substituting simple values in place of variables.

This works especially well in quantitative comparison questions.

For example,

Topic: Algebra
Difficulty Level: 1

Q. Compare quantities A & B and choose the correct option.

1. Is A greater than B?
2. Is A lesser than B?
3. Is A equal to B?
4. Insufficient Information

The answer to this question is option 2: A is lesser than B.

91热爆 Pro Tip: Substitute numbers in place of equations because the solution required is not the answer to the equation but the comparison between the two.

TECHNIQUE #4: Backsolve!

You can plug in different answer choices into appropriate parts of the question in an effort to  work backwards. This tactic is especially useful if you want to bypass difficult calculations.

For example,

Q. Find the radius of the cylinder when h = 3 cm and volume = 38 cm鲁.

1. 1.5023
2. 1.7532
3. 2.0081
4. 2.3156
5. 3.1234

Solution:

V =蟺 x r虏 x h
38 = 3.14 x r虏 x 3
38/(3.14 x 3) = r虏

Therefore, r = [38/(3.14 x3)]陆  is a long calculation and a waste of time.

Instead, try backsolving! Plug in an answer into the formula and compare it to the given volume.

Option 1: 1.52
V = 蟺 x r虏 x h
    = 蟺 x 1.52 x 3
    = 3 x 2 x 3
    = 18

Option 2: 1.72
V = 蟺 x r虏 x h
    = 蟺 x 1.72 x 3
    = 3 x 3 x 3
    = 27

Option 3: 22
V = 蟺 x r虏 x h
    = 蟺 x 22 x 3
    = 3 x 4 x 3
    = 36

Option 4: 2.32
V = 蟺 x r虏 x h
    = 蟺 x 2.32 x 3
    = 3 x 5 x 3
    = 45

TECHNIQUE #5: Tackle word problems one sentence at a time.

Don鈥檛 be overwhelmed by the size of the word problem.

These type of questions generally worry students because they have to understand the question in English and then convert the statements into mathematical equations.

91热爆 Pro Tip:听 Remember to Divide & Rule. Write down what is given and what needs to be solved separately. Use the given statements to form equations and you鈥檒l be able to find what鈥檚 needed.

Q. “A boy scored 80% in 4 tests of 100 marks each. Which of the following is closest to his score in the 5th test, with a total of 250 marks, if he raised his overall average by 5%?”

Solution :

The boy鈥檚 score after 4 tests is 320. — (1)Using given statement 1 鈫� 80% in 4 tests of 100 marks each 鈫� (80/100)*4*100 = 320

Using given statement 2 鈫� 5th test is for a total of 250 marks 鈫� Total marks = 400 + 250 = 650.

Using given statement 3 鈫� Overall average is increased by 5% after 5th test 鈫�

Overall average before 5th test = 80%.

After 5th test, overall average = 85%.

The boy鈥檚 score after 5th test = 85% of 650 = 552.5 — (2)

Therefore, for 5th test score is = 552.5 – 320 = 232.5

Therefore, the boy鈥檚 score in the 5th test is 232.5 out of 250!

TECHNIQUE #6: Pay attention to the units, scales and values along X & Y axes in a graph

Another reason why students lose out on a perfect score is because they glance at the graph and not analyse it thoroughly.  Especially those that have multiple questions based on them.

Take your time to understand what the graph represents.

Read the title for a clear understanding of the graph.

Learn to approximate accurately.

Units as required by the question.

91热爆 Pro Tip:听 Keep a note of the mistakes you make. You can also track it topic wise so that you know just where you need to focus.

TECHNIQUE #7: Take as many timed, full-length tests as you can.

The 91热爆 lasts for 3 hours and 45 minutes. It is mentally challenging as well as physically taxing. But with the right amount of practice, you can train your mind to stay alert throughout.

Most of our students say they don鈥檛 feel the time passing by and before they know it, the most important exam of their lives is over!

Don鈥檛 let that happen to you. Pace yourself using timed tests.

You need to:

• Keep your cool. Don鈥檛 get too worked up or frustrated when you can鈥檛 figure out the answer to one particular question.
• Have the right judgement to leave it in your first pass, move on to answer the rest of the questions and then come back and solve this question later on.
  If you adamantly stick to one question, thinking you have to finish it before moving on to the next, you run the risk of messing up even the portions/sections that you know very well and end up scoring way below your expectations.

We understand that managing time might be difficult especially when you have the pressure of doing well in this exam at the back of your mind. But you need to understand that trying to hurrying up and haste will get you nowhere rather reduce your chance at getting top admits.
You certainly wouldn’t want that to happen, would you?

If the answer is an obvious NO, then check out the following tips that we have collected from personal trainers who have helped over 30,000 students score high in 91热爆. So, sit back, relax and take notes.

1. Allotting 听numbers to questions and neat rough work

Try to put question number and do your rough work neatly. Proper rough work is very useful as it can save you a lot of time when you go back to the unanswered question. If your rough work/calculations are spread all over the place, it will be difficult to locate them. Starting the calculations afresh mean you will end up spending more than 2 minutes and which is very unwise.

2. The IGMO method to save time

The IGMO method requires you to:

• Write all the questions in a piece of paper.
• Calculate the answers to the questions corresponding to the question number.
• If you are stuck on a question make an intelligent guess and move on
• Come back to the question later on and solve it.

Remember you shouldn’t spend more than 2 minutes on one question.
You can give an intelligent guess by eliminating the options that totally violate the given conditions. Revisit those questions in the end.听

This is what it looks like, when you mark a question and later on come back to answer it. It also shows a list of answered/incomplete questions.

3. Don鈥檛 leave questions unanswered

There is no negative marking in the 91热爆 exam, so it is advisable to make a choice by intelligent guesswork rather than leaving a question unanswered. In a multiple choice question with one option to choose from four, your odds of getting it correct are 25%. So you have got nothing to loose. So answer all the questions. That doesn’t mean you will use rock-paper-scissors to decide the fate of the answers!

Our 91热爆 experts have worked out the appropriate amount of time you can spend on the different types of questions. It is listed as below:

4. Spend less time on simple questions

Try to solve the simple questions in less time so that you can spend more time on questions of higher difficulty level and DI questions. Answering the questions that seem simpler will help you dedicate more time to questions that seem harder. Once you have practised hundreds of questions during 91热爆 prep, you will intuitively know which one is difficult and which one is relatively simple. Besides, with ample practice comes this ability of recognizing questions of similar nature that you have solved before. This greatly increases your speed.
The difficulty level of questions vary from 1 to 5. The level 1 and 2 questions can be should be answered in 30-60 seconds.
To give you a brief idea about the difficulty level, here are some questions with their answers:

Question 1听
Question Type:听Data Comparison
Difficulty Level:听Level 2

ABC is a triangle right angled at A. Angle ABC and angle ACB is y掳 and z掳, respectively.

x掳 is an exterior angle at point B of the triangle.

Quantity A: x
Quantity B: z

Options:
Quantity A is greater
Quantity B is greater
The two quantities are equal
The relationship cannot be determined from the information given.

Answer:
Quantity A is greater

Explanation:
Given, ABC is a triangle right angled at A.
Angle ABC and angle ACB is y掳 and z掳, respectively.
=> y + z = 90掳
=> z = 90 鈥� y
x掳 is an exterior angle at point B of the triangle
=> x + y = 180掳
=> x = 180 鈥� y
x = 90 + 90 鈥� y
x = 90 + z
=> x > z
=> Quantity A is greater

Question 2听
Question Type:听Numerical Entry (No options required)
Difficulty Level:听Level 3)
Set S contains the set of all non-negative integer n that is divisible by 6. If n < 100, what is the probability that a number chosen at random is divisible by 12?

Answer:
(9/17)

Explanation:
S = {0, 6, 12, 18, 鈥�, 96} => n(S) = 17
Set of all numbers that are divisible by 12 = A = {0, 12, 24, 36, 鈥�, 96}
=> n(A) = 9 Required probability = 9/17

Suggested question Timeline -91热爆 Quant

You should try and complete the exam in 30 minutes, which will allow you to go back and solve the unanswered questions in the last 5 minutes. You could even revise during those 5 minutes.

5. Use the on-screen calculator

It would consume more time for computing manually, so it鈥檚 better you take diagnostic tests and use the on-screen calculator as much as possible. Note that the calculator in 91热爆 is a BODMAS calculator which operates a bit different from the normal hardware calculators. Try to perform all the simple calculations in your mind without wasting your time typing in the numbers and waiting for the result.听Do get used to this calculator during your practice phase.

You should be familiar with the following functions, depicted:

on-screen calculator – 91热爆 Quant

6.听Beware听of the exam situation

Now you should听understand听that exam hall might not be the ideal test taking environment that you 听thought it would be. The A/C might be working a tad bit slower or faster, hence cooling at different rates which can make you uncomfortable. The invigilators might be a tad bit too harsh. Apart from all that there might be some ambient noises that interrupt your concentration while answering the questions. Make sure that you eat properly before going for the exams. The pantry/food court of the exam center might not be too far to go to in those 5 minutes of break available. You have to keep all these things in mind while you take mock/full-length tests at your home.

7. Take care of the background timer

While you’re taking 91热爆, you can’t carry your wrist watch along. So, the only way for you to keep track of time would be the time running in the background. Now, most test takers feel a great deal of difficulty in keeping up with the preset timer. So, you should ditch the trusty wrist watch and start using a stop watch to time your mock/full-length adaptive tests.
