Data Sufficiency Questions in CAT – Tips and Tricks to Solve

June 27th, 2020 by

Nowadays, everything revolves around data, all major decisions are made by first collecting the mass information and then analyzing the raw data. Whether it may be a small firm, a giant MNC or governments all rely on the inferences made on this massive data. Thus, we cannot undermine the resourcefulness and significance of data. But mere collecting data is not sufficient. You have to consider that while collecting the data all the relevant information required to make inferences is covered otherwise the whole exercise of collecting and interpretation of the data proves to be a futile activit

June 2nd, 2020 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

CAT Concepts – Introduction to Data Sufficiency

Data Sufficiency questions often involve very simple calculations. This does not mean that the questions are simple. It just means that the chances to make conceptual mistakes and / or silly mistakes are a little higher than usual. You will need to pay attention to detail in such questions. In Data Sufficiency, you need to figure out whether or not the data given in the question / statements is good enough to find out a unique answer. Once again – is the data enough to find out a unique answer?  Please note that in Data Sufficiency: You do not need to find out the answer Yo

Application of Quantitative Ability Concepts in Logical Reasoning Puzzles and Data Interpretation Sets

May 6th, 2020 by

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

Basics of Data Interpretation – Approximation

May 5th, 2020 by

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

April 30th, 2020 by

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
