LRDI Introduction

This section of CAT is divided into Logical Reasoning and Data Interpretation. LR on this test focuses on the ability to analyze and understand logical patterns. These patterns can come in forms of puzzles, cubes, networking, clocks, and direction based questions etc. The LR section has a more practical approach to the questions asked, which implies that it has moved away from bookish knowledge.

On the contrary, DI tests an individual’s ability to comprehend tables, charts, and an assortment of graphs. Moreover, it also aims to polish and improves the interpretation of these bar charts, pie graphs, maxima/ minima, games & tournaments, reasoning based and tabular graphs etc. This, however, applies a previously utilized approach to evaluating the student’s capabilities and its roots are embedded in theory. For LRDI it is essential to gauge the techniques that can be applied to answer the questions rather than concentrating on what has already been studied.

The course overall intends to prepare candidates to attempt these questions with utmost confidence. Rodha incorporates more than 100 traditional and conventional caselets sets that cover concepts from almost all subareas. Furthermore, the difficulty level of these questions is deliberately chosen to be 20% higher than actual CAT questions.

If you understand the dynamics of the LRDI section and what can be expected, then you can employ the following tricks to ace the test;


Notice the words used in the question:

"ONLY" and the phrase "IF AND ONLY IF" are certain phrases that must be paid attention to. These words or phrases provide the basis of a ‘condition’ in the question that you should be mindful about because these words can play a significant role in precisely indicating the facts to be used in your reasoning. Other qualifying words such as "other than," "all" or "none" are important as well.

Do not assume:

NEVER utilize or assume any information/date that this not specifically mentioned in the question. Always remember that it is NOT an assessment of how much knowledge you acquire regarding the subject. Rather you must only consider the facts and figures provided within each reading passage when deciding among the alternative responses.

Selecting a response:

For questions that ask you to pick a compelling conclusion, always opt for the one conclusion that unquestionably follows from the data that you are provided. Whereas in problems that ask you to uncover the invalid option, select the one conclusion that does not trail from the information.

Assessing Difficulty Level:

Do not panic if you encounter a challenging question while taking the test. Simply, write down facts, or draw a diagram on your “scratch paper “so that you can substantiate your thought procedure. You can also leave the difficult questions and return to them later.
