February 19th, 2013 by

Heads of Bodies – National and International   When it comes to MBA entrance exams life 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. (F) indicates that the person is a fema

Clocks -Fundamental Principles

February 19th, 2013 by

CLOCKS – FUNDAMENTAL PRINCIPLES   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 proble

Solved Example #16

February 19th, 2013 by

Question : Find the No of zeroes at the end of 25! +26! + 27! + 28! + 30!   Answer :  To understand this, let us understand the basic idea first What will be the number of 0s at the end of a + b + c would depend upon the least number of 0s that any one of a or b or c has. For eg: 300 + 120000 + 17272730 will end in 1 zero But, if they have the same number of zeroes, we will also have to consider the last non-zero digit. For eg: 12000 + 161237000 + 1212331000 will not end in 3 zeroes but in 4 zeroes because the last non-zero digits 2, 7 and 1 will add up to generate an extra zero.

Personal Interview Skills   Dear Student, In this session I would like to cover some of the basic ideas about personal interviews. Since brevity is the soul of wit, and tediousness the limbs and outward flourishes, I will try to be brief. Whom do the interviewers select? The candidate they “like” – so your job is to be “liked” by the panel. Attributes that normal panels like: Honesty Be ruthlessly honest in your answers You should know your subject You should understand your immediate environ Your answering should demonstrate analysis Listen to

Games and Tournaments – 2 In my previous post, we discussed about two of the popular types of questions when it comes to games and tournament questions. So, if you are looking for questions on new types of data representation or questions based on seeding in a tennis tournament, probably you should read that. However, there is another popular type of questions with respect to Games & Tournaments and that is – Football / Hockey tournament questions in which we have to find out Goals scores, winners, ties, etc. In such tournaments, all competitors play a fixed number of matches.

Games and Tournaments

February 16th, 2013 by

Games & Tournaments   In Logical Reasoning very often we encounter problems based on games of tournaments. The first thing that as a CAT taker you need to realize is that such tournament based format offers the examiner a multitude of options. So, there cannot be a set formula for solving such kind of questions. However, if you look at the CAT papers of past few years – a pattern seems to emerge. Let us discuss couple of them.   Type 1: The questions are typically in a set where the data will be either in the standard tabular format or a format which you would never find

Cubes and Matchstick Problems   ‘If it was so, it might be; and if it were so, it would be; but as it isn't, it ain't. That's logic.’ – Tweedledee in Lewis Caroll’s Through the Looking Glass. If the above line confused you, trust me – you are not alone. Even God can vanish in a puff of logic. To know how, you can probably jump to the end of this post. To those who choose not to skip – let us discuss few common types of Logical Reasoning problems.   Type 1:  Cube problems:  A cube is given with an edge of unit ‘N’. It is painted on all faces. It is cut i

Set Theory- Maximum and Minimum Values

February 16th, 2013 by

Set Theory - Maximum and Minimum values   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; I

Permutation and Combination – Distribution of Objects

February 16th, 2013 by

Permutation &Combination - Distribution of objects   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 & 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 P & C is one of the dreaded topics but I hope that once you understand the fundas given below, your fear will reduce. Funda 1: De-arrangement If ‘n’ distinct items are arranged in a row, then

Permutation and Combination – Fundamental Principle of Counting

February 16th, 2013 by

Permutations&Combination-Fundamental principles of counting   For this series of articles, I am assuming CAT 2013 would be the first time you would be attempting CAT, which essentially implies that you are not well versed with the basic ideas behind the Quantitative Aptitude portion. In the latter half of the year, I would move to slightly more advanced topics as by then, you would also have moved to the advanced stage of preparation. I have often seen students struggle with the topic – ‘Permutation & Combination’. As a matter of fact, I have even seen some faculties
