What are the chances that it will rain today? Which team has odds in favor in today’s cricket match? What is the probability that Sensex will close above 30K today? All these questions pointed towards the chance, the likelihood of happening the uncertain event. And to determine this chance there’s a technique, a special mathematical and statistical subject entirely related to this known as Probability. Probability is nothing else but a chance that some event might occur. More formally, it calculates a numerical value between 0 and 1 that represents the likelihood that an event might occu

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

In this post, we will be discussing mean, median, mode concepts and their solved examples which is a frequently asked topic in XAT and SNAP examination. We will start our discussion with basic concepts of statistics followed by some examples that will help you get a better understanding of the concept. The short tricks to solve some particular questions are discussed during the solution of the question.
1. Mean, Median, Mode Concepts and Properties
Mean, median, and mode are three kinds of "averages". There are many "averages" in statistics, but these are, the three most common, and are

Most of us are lured to attempt Para jumble/sentence completion questions in CAT/Mock CAT. In these type of questions, we eventually, come to down to 2 confusing choices. And the sad story is, most of the time we select the wrong option.But, the irony is it’s hard to leave these type of questions as with added logic these questions can be very scoring and consume less time as compared to an RC. So let me try to spread some gyaan that might be able to help you out in these situations.
First ,try to find the purpose behind the para:
When the purpose is to explain something – the

In the recent CAT papers, we have seen questions in Logical Reasoning and Data Interpretation section based on the concepts from Quantitative Ability. These questions can also be solved with simple logic but if solved with the Quantitative Ability concepts then solving becomes more convenient. Topics such as Mixture-Allegation, Percentages, Linear equations, numbers etc. are used to frame questions. In this post, we will look at some of the Quantitative Ability based applications in this section of CAT. We will not discuss the Quantitative Ability concepts in this post, rather we will impl

We all know what factorials (n!) are. They look friendly and helpful but looks can be deceiving, as many quant problems have taught us. Probably it is because that Factorials are simple looking creatures, most students prefer attempting questions based on them rather than on Permutation & Combination or Probability. I will cover P&C and Probability at a later date but in today’s post I would like to discuss some fundas related to factorials, which as a matter of fact form the basis of a large number of P&C and Probability problems.
Some of the factorials that mig

The most important part of CAT Verbal reasoning are questions based on assumptions and inferences. If you think you would rather skip this tricky topic- Well, you shouldn’t. Why? Because once you learn to tackle these well, they can prove to be the most scoring and time-saving questions of CAT. The purpose of such questions is to evaluate your reasoning skills. And you can definitely develop these. How? Just concept clarity and lots of practice!
Students are often confused between assumptions and inferences. While it may not matter in case of easy questions but you need to know the differ

There are some topics in Quantitative Aptitude, like Permutation & Combination, where you can easily find out the answer and the answer you calculate is there in the options but it turns out to be wrong. And then there are some topics in which you read the question, understand it but cannot even begin solving it. You get stuck at the first step and you have no idea about how to even approach the question. The irritating fact is that you understood the question properly. It happens very frequently with questions on Time Speed & Distance (TSD). I have always been a big advocate of

The Game of Thrones - Reading Comprehension
We all have our monsters, demons, the lords of the netherworld that haunt our darkest nightmares. For most CAT takers, there is an unsettlingly large variety of them.
A grammar question is a Mothman (Watch “The Mothman Prophecies” starring Richard Gere). You constantly tell yourself that there is going to be no Mothman anywhere, but you NEVER forget that there may be one right beside you. Grammar, in fact, could even be the dark, omnipresent, omnipotent crime lord Keyser Soze (Watch “The Usual Suspects”) – you don’t have to believe in

Nowadays, loan has become crucial part of our life. We all have learnt living our life on credit. Whether be it a businessman taking loans to run his business or a household to buy a car, everyone has become dependent on sustaining their life and fulfilling their wishes with the help of these loans. But, when the amount has been borrowed then it has to be returned too and now not just the principal loan amount but some interest as well. Interest plays a very significant role in our life. It is a deciding factor whether or not loan has to be taken or not as higher the interest then higher t
