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

Looking for the Best Coaching Classes for CAT? One of the first things that CAT aspirants look for, specially those appearing for the first time, is a "coaching institute". The choices, more often than not, are mind-boggling and confusing to say the least. Also, everyone wants to join the "best coaching classes" and the "Top CAT Coaching Institute" in the city. And as the bard would say, therein lies the rub. The coaching institute you pick is going to make very little difference to the final result. But then again, everyone wants the "best". I thought I will write this post to share my t

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

A pipe is connected to a tank or cistern. It is used to fill or empty the tank; accordingly, it is called an inlet or an outlet. Inlet: A pipe which is connected to fill a tank is known as an inlet. Outlet: A pipe which is connected to empty a tank is known as an outlet. Problems on pipes and cisterns are similar to problems on time and work. In pipes and cistern problems, the amount of work done is the part of the tank of filled or emptied. And, the time taken to do a piece of work is the time take to fill or empty a tank completely or to a desired level. Pipes and Cisterns Po

Time, Speed, and Distance is a very crucial topic in quantitative aptitude section of CAT, SNAP, XAT etc. Every year 4-5 questions are asked from this topic. We all have done questions based on Time and Distance in our high school maths but you might not be acquainted with this very significant part of the application of this concept knowns as Linear and Circular Races. You might have done some simple problems based on this concept but not enlightened with its model and theory. In this blog, I will provide you a summarized knowledge of this concept along with it’s application in forms of

By now, you must be aware of 50% topics of the verbal ability section- vocabulary & RC. Let’s move on to another crucial part of VA, i.e. Verbal Reasoning. As the name states itself, this section intends to assess your reasoning skills. One of the most important types of questions in this section is based on paragraph summary. So, what is a paragraph summary? If someone asks you to summarise a 3-hour movie, how would you do that? And if it’s your favourite movie? Well, that’s the very purpose of summary questions. All you need to do is understand the paragraph and then, figure

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

No other question in the CAT is as deceptively simple as Paragraph Completion questions. Superficially, they do not require us to know or remember any rules. They, in fact, require us to do something far more difficult – to think like the writer. Since the last week’s post on Parajumbles, I have been thinking hard over an appropriate parallel to explain the process of solving Paragraph Completion question. And all my thoughts end once again at the same point – Sherlock Holmes. Indeed, picking up the scattered clues, and building them into a clear chain of reasoning for anticipati

Ratio and Proportions is one of the easiest concepts in CAT. It is just an extension of high school mathematics. Questions from this concept are mostly asked in conjunction with other concepts like similar triangles, mixtures and allegations. Hence fundamentals of this concept are important not just from a stand-alone perspective, but also to answer questions from other concepts 1.  Ratio (Concepts and Properties) Many a times we compare two data values of the same type. One way to do this is to find out the difference (a-b). Other method of comparison could be by division or finding out

Sentence exclusion questions test one important skill: to detect an anomaly in data. The fly in the ointment. The scratch on the lens. The bug in the software. The Van Buren supernova – that did not exist in the original Vermeer painting – which Sherlock must discover in order to beat Moriarty’s deadline of 10 seconds. Indeed, if approached logically, it should be a 10 or may be 20 or 30-second affair to spot the odd sentence among the given four. How to approach a Sentence exclusion question: Sentence exclusion is a new twist on the old Parajumbles question. A â
