Learn the Basics of Time, Speed & Distance for CAT Exam

April 22nd, 2019 by

I guess my first fascination with problems of Time, Speed and Distance began when I first saw Henna. An important part of the story line  if you can call it that, saw Rishi Kapoor floating from India to Pakistan without drowning. I remember arguing with my friends that if could float for that long – he could swim back to India as well. My friends nullified the argument by saying: Speed River > Speed Rishi Kapoor I know that the reference is a little dated for most readers of this post, but Zeba Bhaktiyar made me look beyond reason. In this post we will discuss some of the ideas that

Mixtures and Alligation Concepts for CAT Exam Preparation

April 11th, 2019 by

The questions on Mixtures and Alligations are asked repeatedly in CAT and keeping the past year trends in mind, one or two questions are asked every year. We have seen the concept used in some of the Data Interpretation questions as well, so this cannot be overlooked.  Let us begin with the subject matter on this topic.

The concepts of Set Theory are applicable not only in Quant / DI / LR but they can be used to solve syllogism questions as well. Let us first understand the basics of the Venn Diagram before we move on to the concept of maximum and minimum. A large number of students get confused in this so I have listed out each area separately. A venn diagram is used to visually represent the relationship between various sets. What do each of the areas in the figure represent? I – only A; II – A and B but not C; III – Only B; IV – A and C but not B; V – A and B and

April 8th, 2019 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.

April 3rd, 2019 by

In this Number of trailing Zeros blog post, We 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

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
