CAT Preparation Guide: Know How to Solve LR and DI

CAT Preparation

Many CAT aspirants find Logical Reasoning and Data Interpretation a herculean task although they might be proficient in Quantitative Aptitude. The struggle is real since there are a number of challenges posed by this section of CAT Syllabus.  As evident by its name the Data Interpretation (DI) and Logical Reasoning (LR) deals with data and it helps to test the ability to analyse and establish the best recourse in a given situation. In this section of the exam, candidates explore calculations as part of Data Interpretation and speedy decision-making ability is brought to test for Logical Reasoning.

Being one of the most important section of the CAT exam, it has seen a rising trend in the level of toughness over the decades. As the section is not optional candidates must at least get the minimum cut-off score to qualify in the exam overall. As a matter of fact, many students mess up their entire percentile because of the LR-DI section.

To help the CAT aspirants address their woes, here are some tips which can give a clear method and direction during the course of preparation:

Make a point to read Business Newspaper and Magazines: It is one of the best and easiest method to analyse and get the hang of pictorial and graphical representations of various statistics and figures in the form of charts, bar graphs, tables etc. It can be easily found on the business corner of newspapers. Business magazines can be of great importance too as it can make you familiar with business aptitude and interpreting data.

Practice Calculation: It is crucial for CAT aspirants to acquire a sound control over mental calculation as it would not only help you in the DI section but also come handy in quantitative aptitude. Although students would be provided with “Basic Calculator” of CAT, it cannot compensate the advantage that the candidates would get if they are well versed with basic mental calculations such as tables till 20, knowledge of fractions from 1/1, 1/2, 1/3 till 1/20, basic addition and subtraction etc.

Practice More Questions: Data Interpretation and Logical Reasoning is kept to 1/6th of the CAT test paper and in order to perform well one needs to gets involved in loads of practice and analyse and keep repeating the loop. It is advisable to the students that they keep solving the DI questions and build their stamina till the time it is set in stone. Consider this as a challenge and avoid using the on-screen calculator and train your mental muscle memory to do all the calculations quickly.

Keep your Concept Clear: Focus more on concept building and less on solving a number of questions as it is essential in the CAT paper especially the DI and LR section, one need to understand the process behind solving a question. Questions on minor topics like Number Series and Direction sense may not appear in the CAT exam but these things can help build your concepts which in turn would support your preparation in a big way.

In terms of real-world equivalents, one needs to not only practice but get familiar with Caselets which is considered by many as one of the most important topics and type of questions asked in the DI and LR section. For instance, you’ll be given a situation wherein the text would be followed by three to four questions. But in Data Interpretation, the cases or questions will be given in the form of line and bar graphs, pie charts etc. Usually, the Logical Reasoning questions on CAT paper would deal mainly on arrangements, blood relations, family tree, Venn diagrams etc. Sectional CAT mock tests can be of great help as it will help you familiarize with the concept and boost your understanding of data representations.
