Logical Reasoning Preparation Tips for MBA Exams - Check Syllabus, Weightage, Practice Questions

Data Interpretation and Logical Reasoning or DILR is one of the main sections of the MBA entrance exams and competitive exams. This section carries questions on a particular situation or graphs/charts/diagrams, etc. which test-takers have to study and examine properly to answer the multiple-choice questions that are related to the caselets or figures and diagrams. DILR section tests candidates’ analytical bent of mind and critical thinking ability.

In DILR, the questions are based on Tables, Graphs (Line and Bar), Charts (Pie, Area, Line), Data Analytic Caselets, Data Structure, Calendar, Clocks, Data Sufficiency, Venn Diagram, Blood Relations, Arrangement (Seating, Linear and Matrix), Coding-Decoding, Logical Sequence, Assumption, Binary Logic and Critical Reasoning

Yes, DILR section is a major section of all the MBA entrance exams. It covers almost 1/3rd of a test paper. In some exams, Data Interpretation is clubbed with Quantitative Aptitude and Logical Reasoning is an individual section. Irrespective of what the composition is, the both DI and LR are a part of MBA entrance exams. The section includes graphs, charts, diagrams, caselets, clocks & calendars, blood relation, family tree, number system, coding-decoding, arrangements and other such topics. There are a few state-level exams like TANCET, which does not have a separate section on DILR area, but the topics from this area are included in Data Sufficiency.

The best way to prepare for DILR section is through practice. Before starting the preparation, aspirants should be accustomed to the question types by going through previous years’ question papers and solving those. Since there is not much conceptual understanding required in this section, practice is the key to excel in this area.

Some of the most popular books on DILR section that you can refer are How to Prepare for Data Interpretation and Logical Reasoning for CAT by Arun Sharma, Logical Reasoning and Data Interpretation for the CAT by Nishit Sinha, Data Interpretation and Logical Reasoning for CAT by Pearson, to name a few.

No, DILR is not a combined section in all the MBA entrance exams. In some exams, the LR section is combined with DI, whereas in some exams DI is clubbed with Quantitative Analysis. For example, in CAT, DILR is a combined section, in XAT, the DI area is combined with Quantitative Ability and LR is combined with Verbal Ability.

The DILR section is also known as Decision Making, Data Analysis, Critical Reasoning, Logical Ability, Analytical Ability, etc. This section is named differently but comprises common topics such as Bar Graph, Line Chart, Tabular Form, Caselet Form, Pie Chart, Missing Data, etc.

CAT DILR is all about practice. So, you need to practice a lot of questions from DILR to be able to master it. This section of CAT is equally divided into 10 questions each on DI and LR. The Data Interpretation questions are based on Mathematical tables, bars, pie charts, etc. so you need to work on it alongside Quantitative Aptitude. Learn some basic rules of tables, bars, pie charts as well as some basic rules of mathematical calculations. If you can read the data correctly, you can solve the CAT questions. However, to be able to solve questions quickly and accurately, you need to practice a good number of sample questions and mock tests.

For Logical Reasoning, you will have to depend totally on practice tests and exercises. The CAT LR questions are mostly based on series, number system, coding-decoding, family tree, circular patterns, blood relations, etc. So, you need to practice a lot of questions on these to be able to solve them in the exam. Go through CAT previous year question papers to know the type of questions are asked and practice them.

In CAT exam, there are 20 questions in the Data Interpretation & Logical Reasoning section and the total sectional marks is 60 out of 198. In CAT 2020, there were 24 question on DILR and the sectional marks were 72. In CAT 2021 and CAT 2022, there were 20 questions and the sectional marks were 60.  The 20 questions are equally divided into both Data Interpretation and Logical Reasoning. That means, Both Data Interpretation and Logical Reasoning have 10 questions each. The questions are mostly in sets. There’s rarely any standalone question in DILR.

Some of the top MBA entrance exams carrying a high weightage of Data Interpretation and Logical Reasoning questions are MAH CET, ATMA, CAT, CMAT, XAT IIFT, to name a few.

The DILR section is mostly practice-based. There is not much theory-based or conceptual parts involved in the question unlike Quantitative Ability or Verbal Ability sections. Here, rather than focusing on the definitions of the topics, students get more accustomed to the question types and excel in the areas through practice. As it takes practice to improve the analytical and critical thinking ability rather than rote learning the concepts.

The Data Interpretation is all about reading and comprehending tables and charts. The questions are calculation based, so you need to a strong base in Maths and practice. Logical Reasoning too is all about deciphering puzzles and patterns so even for that no theoretical knowledge is required. Practice questions are the key.
