It can be argued that Quantitative Aptitude is the section that makes the most amount of difference in the CAT results every year. If you look at the data from the past few years, you would realize that the Logical Reasoning and Data Interpretation section has remained the toughest section. You normally need to do only 9 questions in it to score a 90%ile. Verbal Ability and Reading Comprehension has remained the easiest section over the years where you have needed to score around 16-18 questions to get a 90 %ile. Quantitative Aptitude, on the other hand, varies a lot. You would need around

Remainders, as a topic, confuses a lot of students. As a matter of fact, a large percentage of CAT quantitative Aptitude questions and doubts on any public forum (Pagalguy / Quora / Facebook) will be dealing with remainders. This is true for the Course Feed of my online CAT coaching course as well. So, I decided to combine all the various kinds of Remainder related questions and make a single post about it. I hope that if you go through the 50+ questions given in this post, you will never struggle with remainders again.
In case you have any doubts with any of the questions, use the commen

Cyclicity of Remainders
In this post I would like to discuss some of the really fundamental ideas that can be used to solve questions based on remainders. If you have just started your preparation for CAT Exam, you might find this article helpful.
First of all,
What I am trying to say above is that if you divide a^n by d, the remainder can be any value from 0 to d-1.
Not only that, if you keep on increasing the value of ‘n’, you would notice that the remainders are cyclical in nature. What I am trying to say is that the pattern of remainders would repeat. Let me try to

Quantitative Aptitude is an important part of the CAT Exam. As a matter of fact, it will not be wrong to say that it is the most important part of the CAT exam because the most amount of time is spent on preparation of the Quantitative section. Should it be that way? – Perhaps the answer is yes for a few students but the actual number of CAT aspirants who make Quant their top priority is much larger than it needs to be a reason. And do you know the reasons behind that?
First and foremost, it is the inherent fear of Math. We are often afraid of what we do not understand fully and Quant

In the previous post we discussed lines, triangles, parallelograms, trapeziums, polygons etc. Now, we will discuss other expanses of geometry which are vital as, the questions on these topics are asked repeatedly in CAT. Let us look at few of the fundas / formulae on these topics that are often neglected by students and can fetch some crucial marks in the exam.
Funda 1: Angle made by Secants
2 .
In both these cases, PA * PB = PC * PD

I got a lot of feedback via emails and texts that people are looking for a post on geometry. I have been avoiding it for sometime because of two main reasons:
a) It is not one of my strong areas.
b) It takes a lot of time to draw the diagrams that are sometimes required to explain the fundas.
The questions on geometry are the trickiest and consumes the maximum amount of time as compared to the questions on other topics in Quantitative aptitude that is why, I have compiled a list of fundas that you might find helpful in solving CAT level questions. I am splittin

A very common type of question that gets asked in various banking and management entrance exams is based upon the concept of finding out the rank of a word. In this post, I will like to discuss the concept behind the same. Let us look at the two types.
Rank of a word - without repetition of letters
Suppose that you are given a word in which none of the letters are repeated and you asked to find out the rank of the word in a dictionary. For example, if the word which was given to you was CAT, it will be very easy to find out its rank. You will write down all possible combinations of

Questions on clocks (or even calendars) are not really frequent in CAT these days. They used to be really popular few years ago. Having said that, it is always better to understand some of the basic principles and the types of problems that get asked. They might come in handy in case of other exams like CMAT, MAT, SNAP, etc.
Clock problems can be broadly classified in two categories:
a) Problems on angles
b) Problems on incorrect clocks
Problems on angles
Before we actually start solving problems on angles, we need to get couple of basic facts clear:

As an astute man Mr. Gump once said, “Life is like a box of chocolates. You never know what you going to get.” The Permutations and Combinations that life presents us daily is baffling and probably it is because of that inherent fear of choices and cases we get intimidated by such questions in the exam. I understand that Permutation and Combination is one of the dreaded topics but I hope that once you understand the fundas given below, your fear will reduce.
Permutation and Combination Funda 1: De-arrangement
If ‘n’ distinct items are arranged in a row, then the number of way

Ratio and Proportions is one of the easiest concepts in CAT. It is just an extension of high school mathematics. Questions from this concept are mostly asked in conjunction with other concepts like similar triangles, mixtures and allegations. Hence fundamentals of this concept are important not just from a stand-alone perspective, but also to answer questions from other concepts
1. Ratio (Concepts and Properties)
Many a times we compare two data values of the same type. One way to do this is to find out the difference (a-b). Other method of comparison could be by division or finding ou
