First of all, a very Happy Republic Day to all our students (and other visitors here). Republic Day honors the date on which the Constitution of India came into force on 26 January 1950 replacing the Government of India Act (1935) as the governing document of India. The Constitution was adopted by the Indian Constituent Assembly on 26 November 1949 and came into effect on 26 January 1950 with a democratic government system, completing the country's transition towards becoming an independent republic. 26 January was chosen as the Republic day because it was on this day in 1930 when the Decl

Highest, Longest, Tallest, Largest, Smallest places form an important part of questions in competitive examinations like XAT, IIFT, IBPS, TISS, Bank PO etc. Below is a list of some of the most important Longest, Largest, Highest places around the World and in India. This post has been divided into two sections, Around the World and Inside India. In the first section, Around the World, all the places have been divided into sub-sections based on Longest, Largest, Highest, Tallest, Smallest and Biggest. In the second section, Inside India, all the places have been divided into sub-sections

In our previous post on games and tournaments part-1, 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 and 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

In Logical Reasoning very often we encounter problems based on games and 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 on Cricinfo or for that matter any o

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

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   Funda 2: Common Tangents     eg: Note: The two centers

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

While most students are comfortable with the concept of HCF (Highest Common Factor) and LCM (Lowest Common Multiple), they somehow fail to apply it when required. Sometimes, they do not even realise that it needs to be applied. I sometimes feel sad when students ask me, “Sir, when to apply HCF and when to apply LCM?”. This question is a symbol of everything that is wrong with rote learning. HCF and LCM are concepts that students start learning as early as the 5th class in school (may be even earlier in some cases). The problem occurs because a few of them forget how the concepts need t

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: Sp
