Basics of Data Interpretation – Approximation

April 13th, 2018 by

Data Interpretation questions typically have large amount of data given in the form of tables, pie charts, line graphs or some non-conventional format. The questions are calculation heavy and typically test your approximation abilities. A very large number of these questions check your ability to compare or calculate fractions and percentages. If you sit down to actually calculate the answer, you would end up spending more time than required and most of us can't afford to lose precious time during competitive exams like CAT, XAT, IIFT etc.  Here are few ideas that you can use for approxim

How to Solve Inference Based Questions in Reading Comprehension for CAT?

April 11th, 2018 by

During discussion of a current affair issue with a friend, I found the below couple of excerpts that instigated to think what I understood from the complete issue and how it can be fit on logical ground from the selection itself are though similar but cannot be handled in the same way. It is applicable for all types of reading. And when logic comes into the picture then with it, it brings premise, conclusion, assumption and argument as a whole. Example-1 “US and Pakistan continue to partner on a range of national security issues. President Donald Trump’s administration appears re

April 6th, 2018 by

When it comes to MBA entrance exams like XAT, CMAT, IIFT, SNAP, etc. the knowledge of the heads of important organizations is really helpful. More often than not, you will end up getting couple of questions on these. There is also a reasonable chance that you will get a question of Match-The-Following type where this information would be really useful. I have compiled a list of the current heads of important bodies and divided into two parts: India & International. Both of them are given below.

March 29th, 2018 by

To understand how exactly these kinds of puzzles look like, let’s start the post with a very simple example.

They have 78 coins and the player who picks the last coin will lose the game. A and B play alternately and A plays the first move. How many coins should A pick at first so h

Words with Similar Meanings and Subtle Differences

March 28th, 2018 by

In the series on confusing words (Part 1, Part 2 and Part 3) we looked at words that sound similar or look similar but mean different things. There is another class of words you should be careful about - these are words that are often used interchangeably (and wrongly at that, I must add). This generally leads to bad writing than bad comprehension when used. You do not need to look far away for instances of not knowing the difference between these similar sounding words. Just ask any MBA aspirant whether have any preferences for specialization and a lot of them say ‘Marketing’. Just fol

Understanding Confusing Words – Part 2

March 19th, 2018 by

In the Understanding Confusing Words – Part 1, we discussed confusing words. As discussed Learning New Words – Why, How and Strategies, these words are not directly related to CAT prep for the vocab section or for any MBA exam (so don't expect direct questions based on these words) but knowing the right words and the correct usage will make your job much easier while attempting questions. Let us extend the list with a few more words. Prescribe vs. Proscribe - These similar sounding words have very different meanings. Prescribe is the more common word, and it's often used at the docto

Understanding Confusing Words – Part 1

March 16th, 2018 by

In the last post we looked at some ways to learn new words - reading with context, flashcards, word group lists and studying by comparing words. We had discussed about identifying words that are confused easily. In this post we will look at some examples involving these confusing words. Now, will a misunderstanding cost you marks in the exam? Not necessarily so, because like we discussed last time, no questions simply ask for meanings of words. However, when you’re reading a block of text and reach this word where you are not quite sure of the meaning, that is enough to cause a problem.

How to Find Number of Trailing Zeros in a Factorial or Product

March 14th, 2018 by

In this Number of trailing Zeros blog post, I would like to cover these two ideas: Number of trailing zeroes in a Product or Expression Number of trailing zeroes in a factorial (n!) But before I begin, let us first try to understand what exactly are ‘trailing zeroes’. It is nothing else but the number of zeroes at the end. I do not want to sound pedantic but on many occasions when you see a question which asks about, “What is the number of zeroes in ___” it is incorrect, because it should actually say – “What is the number of trailing zeroes?” or “What is the n

Learning New Words – Why, How and Strategies

March 12th, 2018 by

Take the previous papers of any MBA entrance exam and look for questions that ask for the meaning of a particular word. The chances are pretty low that you will find a multiple choice question of the format - “The meaning of X is:” followed by four options. Doing the same thing for antonyms or idioms will probably not give you a lot of questions either. So no exam is going to ask you for word meanings. If so, then why learn new words, antonyms or idioms if they are not asked as direct questions in the exams? It starts with having a large list of words at your disposal so that
