DILR Preparation Tips for MBA Exams 2025 - How to Prepare for DILR in MBA Exams

Edited By Team Careers360 | Updated on Sep 18, 2024 10:46 AM IST | #CAT

Data Interpretation (DI) and Logical Reasoning (LR) combined called DILR, is a very important section for MBA entrance exams. As per the trend of the previous year’s results, this is the weakest section for most of the aspirants. This is very time-consuming as well as difficult. So making a CAT Preparation strategy, practising, persevering, and getting familiar with this section before appearing in the exam is an essential thing every student should do.

What is Data Interpretation & Logical Reasoning (DILR)?

Data interpretation (DI) means interpreting the given data and solving the questions based on the data provided in a set. These sets can be of various types like tables, pie charts, bar graphs, caselets, etc.

In the Logical Reasoning (LR) part, students must solve problems based on logic like puzzles, seating arrangements, blood relations, and pattern identification. Understanding the CAT 2024 Data Interpretation syllbaus is also very beneficial for the candidate.

DI portion mostly focuses on numerical data and has to do mathematical operations like average, percentage, or ratio to find the answer. On the other hand, in the LR part, analytical thinking is the most important thing. Most of the questions in LR sections are puzzle-based, where students have to use methodical reasoning and strategy to reach a conclusion and solve the questions.

The DILR section is important in exams like CAT, XAT, and other MBA entrance tests. In the CAT exam, for the previous five years, almost 20 questions with a weightage of 60 marks from the DILR section came. 70-75% of the DILR questions are multiple choice questions and 25-30% of questions are non-multiple choice questions. The level of difficulty in this section is moderate to hard.

Answering these questions can be very time-consuming as the questions are generally very tricky and difficult.

What are the Skills Required to Crack DILR?

To achieve good marks in the DILR section, students should follow the following skills and try to improve them in time.

Analytical Thinking

Analytical thinking is an important skill for solving any type of complex problem. First, you must break down the problem into smaller parts to analyze it easily. It will also help you to follow patterns or trends, establish relationships between the given data, and calculate the numerical values using various mathematical operations.

In the DI part, students have to deal with lots of bigger puzzles. So analytical thinking is a very important skill to solve these puzzles.

Practice mental maths to solve basic maths quickly and efficiently without using a pen or paper. This will save lots of time during the exam.

Data Analysis and Interpretation

In the DI section, there will be lots of charts, graphs, tables, caselets, etc. So, analyzing the data to check the pattern or trend, handling numerical values, and drawing conclusions are very important to solve these types of problems.

The correct results in the DI section are obtained through accurate data analysis.

Often students need to use mathematical operations like percentages, averages and ratios to get the result. So knowledge about these operations is also very helpful.

Logical Thinking

Logical reasoning(LR) section is mostly about logical thinking. In this part, problems like seating arrangements, blood relations family tree problems, or pattern recognition types of problems appear.

Logical thinking will help you to deduce these problems and draw conclusions based on the given data.

Like in blood relations family tree problems, you have to establish relationships between the persons given the constraints in the data.

Time Management

The DILR section is one of the most time-consuming parts of the exam. Understanding these questions and deducting them from the data often consumes lots of time in the exam. Students have to strategically approach this section.

Balancing speed and accuracy is essential to score good marks. Students have to decide whether to skip a set or attempt a set after reading it once or twice. If the set is very complicated, then skipping it for the time being is the best solution. Return to it if you have time left at the end.

Problem-Solving Skills

The DILR section is all about solving complex and multi-layered problems. So, students must strategize problem-solving skills like identifying the correct pattern, making notes of important data and arranging them logically, and eliminating the odd options in the multiple-choice questions to ace this section in the exam. It will also help to minimize the errors and increase the accuracy.

How to Prepare for Data Interpretation and Logical Reasoning for MBA Exams?

To prepare for Data interpretation and Logical reasoning for MBA entrance exams, students need to follow some basic rules. Following these rules will give them a strong base on which to score good marks in the DILR section of the exam.

Building a Strong Foundation

Before appearing in the exam, students should build a strong foundation in Data interpretation and Logical reasoning questions.

Data interpretation questions are mostly about interpreting data from types of sets like charts, tables and graphs. However, in the logical reasoning questions, students are required to apply reasoning when seeking logical answers.

Begin from the beginner books and materials, then progress to the more advanced sets. Accompany yourself with those types of problems and be ready for the problem in the exam.

Practising Mock Tests and Sample Papers

Students need to practice the previous year's questions first to get a good idea about what types of questions generally come in the exam and know the difficulty level of the questions.

Practicing different kinds of sets helps you do all of this better, and is, therefore, an absolute necessity.

Giving 3 to 4 mock tests every week will help students get an overview of the exam conditions and improve their time, speed, and accuracy. Students need to evaluate those tests to check where the mistakes are generally happening or in which portions of the set are taking more time. Then work on those weaker areas and refine strategies accordingly.

Developing Sectional Time Management

Mental endurance is very important in time-based exams. Set a timer during giving offline mock tests so that you don’t get distracted. Try to finish the exam at least 5 minutes before the allotted time to check all the questions once.

As discussed before, the DILR section is very time-consuming. So it is very crucial to decide where to invest more time. During the mock tests, evaluate your strengths and weaknesses in the DI and LR sections and strategize accordingly. Then during the exam, approach your strong section first to secure the numbers. Then do the comparatively weaker section. But don’t neglect it fully as it is also important to achieve success.

Answer:

Putting all the given information in the table given below, we get:

1726634677925

From statement [4], we can say that Q and U are females because we know P and T are males and there are three males and three females.

T does not play Tennis and Racing.

Four games Cricket, Tennis, Carrom, and Swimming are played by R, S, Q, and U respectively.

Therefore, T participated in shooting and P in Racing.

Therefore we have,

1726634678232

Now all the questions can be answered.

If Q is in standard IV, then U is in standard V.

Therefore, U takes part in Swimming.

Hence, the correct answer is “V”.

Important Topics to Focus on for DILR in MBA Exams

Now, we will discuss the important topics of DI and LR separately and how to deal with them.

Data Interpretation

  • Tables and Charts Interpretation: These types of questions consist of numeral data and students have to extract, interpret, and calculate those data. Knowing mathematical operations like percentages, averages, and ratios is very important in these questions.

  • Bar graphs, Line graphs, and Pie charts: A pie chart is divided into sectors, each representing a proportion of the whole and is effective for showing the relative sizes of parts of a whole.
    Line graphs display continuous data or a sequence of values.
    In the Bar graph, data is represented with rectangular bars where one parameter is given on the x-axis and the other parameter is given on the y-axis.

  • Caselets and Venn diagrams: A Caselet is a collection of facts presented in the form of paragraphs.
    Venn diagrams are typically used in set theory-based questions where students need to interpret overlapping sets and draw logical conclusions about the relationships between different categories.

Logical Reasoning

  • Arrangements (Linear and Circular): In this type of question, students need to place a certain number of people in a linear straight line or circular line. In circular line questions, having an idea about clockwise and anti-clockwise directions always helps students.

  • Puzzles and Seating arrangements: Puzzles are often straightforward to more complex logical deduction-type problems. In seating arrangement problems, students have to place some people in order.
    Problems on puzzles need to be handled systemically and solving sudoku in the newspaper with help you, on the other hand for seating arrangement problems, approach with a starting position or ending position.

  • Syllogisms, Blood Relations, and Statements & Conclusions: In syllogism questions, students have to draw conclusions from two or more statements. In blood relation problems, students have to draw a family tree to analyze and it will test their knowledge about family relationships as well. In the statements & conclusions type of problems, students have to logically deduce whether the given conclusion is apt or not from the given statements.

  • Logical sequences, Series, and Coding-decoding: In logical sequence and series problems, students have to find patterns between numbers, letters or objects and fill in the blanks with relevant information. Coding problems generally appear in the form of a code and students have to decode the problem to answer the question. Strengthening pattern recognition is very essential to solve these types of problems.

Common Mistakes to Avoid in the DILR Section of CAT 2024

Based on the trends of the previous year, some common mistakes students make during exams are as follows:

Try to understand the mistake and make a strategy accordingly so that you can’t make the same mistakes.

Rushing Through Complex Problems

After practising too many DILR questions, students sometimes get overconfident in the exam in this section and often adjudge complex sets as like other sets. But complex sets are a bit tricky and those need to be handled very carefully.

Give adequate time to complex sets and don’t rush over quickly to jump to conclusions. Double check is always necessary for accuracy. If the sets seem too complicated, then it is best to skip them for the time being and visit them at the end.

Misinterpreting Data

Misinterpreting data in the DILR section is the most common mistake among students. Students often rush through the data and miss a constraint in the data or misread axes. This leads to the downfall of the whole set and students get wrong answers to the questions of that set.

To avoid that mistake, double-check all the data and mathematical calculations. It is always better to be accurate to perform well in this section.

Spending Too Much Time on a Single Question

The DILR section is always time-consuming. So allocate a time limit for each set like if it looks like a moderate set then do it for 7-8 minutes and if it looks hard then do it within 10-12 minutes.

Do not overspend much time in a question and try to attempt the easier ones first. Otherwise, you will waste too much time on difficult questions and potentially easier questions will be left unattempted.

Not Practicing Enough with Mock Tests

Practice makes a student perfect. Many students often do not practice enough mock tests and think they will manage their time directly in the exam. This thinking is not right. For time-based exams, students need to practice at least 3-4 time-based mock tests every week to get familiar with the time constraints and strategize what time to invest in each part. A perfect time division strategy will often lead to success.

Also, rectify the mistakes which happen in the mock test and prepare those topics well so that the same mistakes do not happen again in the actual exam.

Preparation Tips for DILR CAT 2024

Understanding the various preparation tips for DILR section of the CAT examination is essential for securing a good CAT DILR score. Some of the essential CAT DILR preparation tips are given.

Start Early and Build Consistency

Starting early and constant practice often lead to success. Don’t wait until two months before the exam to prepare for this important exam. At least start 6 to 8 months before the exam and practice thoroughly. Building a foundation is very important to succeed in any kind of exam. Start with the basics and step by step move from moderate to hard. Don’t jump a step as gradually increasing difficulty will help you to improve your mindset and accuracy.

Focus on High-Weightage Topics

Analyze at least the previous five-year questions to get an idea about the trend and most important topics in this section. The most frequently asked topics in this section are tables and Charts Interpretation, Puzzles and Arrangements, and Logical Sequences.

Give more importance to these topics and practice several questions on these topics.

Develop an Effective Exam Strategy

To succeed in any kind of exam, strategy is equally important as studying. Set time limits for each type of set beforehand and try to analyze quickly which sets are harder. During the exam, attempt the easier sets and questions first. This will boost your confidence. Don’t hesitate to leave complicated or time-consuming questions for later. Focus on accuracy rather than attempting most of the questions with guesses.

Avoiding these mistakes will eventually lead to success.

The student cannot join the postgraduate MA program directly in the second year of the MA after completing the MBA.


Universities generally expect students to begin the first year of a masters' program even though they had qualifications at the level of a bachelor's degree. The university's curriculum along with the courses are planned to give an in-depth knowledge of the subjects.


But you could opt for:


Postgraduate Studies:


Research Career: In case research interests you, then you can pursue a Ph.D. in your specific interest.

Specialized Master's Programs: Find any specific master's course that supports the career goal.

Professional Certifications:


Make a professional certification in CFA, CA, or FRM to enhance the professional skills and better opportunities in the career field.

Job Entry via MBA

After gaining an MBA from a renowned institution, it's possible to get entry into the corporate world where the diversity in the career field is assured.

In the end, it would depend on what you would like and what you are particularly interested in. It will be better if you take a suggestion from your academic advisor or career counselor.

Hello Pratik,

If your family income exceeds 8 LPA, it will affect your eligibility for the NC-OBC category under the CAT reservation rules. The NC-OBC category requires that the family income should be below 8 LPA to qualify. If you anticipate that your income will exceed this threshold, you should update your status and notify the CAT authorities .

Here's what you can do:

  1. Email the CAT authorities : Inform them about the potential change in your income status and request to be considered under the General category, if applicable. You should do this before the examination or any further processing, as your eligibility for the OBC category depends on the income criteria.

  2. Documents and Proof : Make sure you have a valid OBC certificate and any relevant documentation regarding your family income, in case they require verification. Also, be aware that if your income exceeds 8 LPA, you might need to apply under the General category, as the OBC-NC reservation is no longer applicable.

  3. General Category Consideration : If your application is accepted as General, you will be evaluated based on the General category criteria, including cutoffs and ranking.

To summarize, notifying the CAT authorities is the correct approach to avoid discrepancies later, and if your income is above the threshold, you will be treated as a General candidate for the admissions process.

Hi Shreya ,

Having a tattoo on your wrist should not  create a problem during the CAT exam as long as it does not contain any content that violates exam rules , such as communication-related symbols , unauthorised messages or any text resembling formulas or answers .

For a safe side , it is recommended :

1. Inform the Invigilators : Let them know about your tattoo during the identification check , so there are no misunderstandings .

2. Follow the Guidelines : Ensure you follow all instructions regarding permissible items and dress code on the exam day .

Hope this helps you .

ALL THE BEST .

Hello,

Yes, you can also join IIMs two years after graduation, depending upon the justification in interviews and your performance in entrance exams. If you are not sure about CAT, try those other management exams less hard:

Common Management Admission Test: Easier than CAT; 4-5 months of continuous preparation will suffice.

MAT : Much easier and takes place thrice a year.

SNAP (Symbiosis National Aptitude Test): A bit easier than CAT, apt for Symbiosis Institutes.

Xavier Aptitude Test or XAT : Hence, easier than CAT but the unique decision-making section.

Use exams like CMAT and MAT as a challenge to be competitively prepared. This can be given about 4-5 months, along with a few rounds of mock tests and smart studying.

Two friends Moloy and Niloy passed out from the Purulia Institute of Science and Technology with B.Tech degrees in Mechanical Engineering, but even after a year placement was hard to find. So they decided to take the challenge head-on, came down to Kolkata, rented a garage space on Park Street, and having an affinity towards making people enjoy good food, started their firm named 'B.Tech Bread-Omlette Wala'. 

They started with three items on the menu. One was the French Toast which could be prepared in 3 minutes. The second was the Egg Tortillas which took 15 minutes to prepare. Any one of Moloy and Niloy could prepare any one of them at a time. The third was the Egg Bhurji with French Fries. This however was prepared on an automated fryer which could prepare 3 servings at a time and took 5 minutes irrespective of the number of servings equal to or below 3. The fryer did not need anyone to attend to it, and the time to put in the raw ingredients could be neglected. So one could tend to the preparation of other items while the Egg Bhurji with French Fries were being prepared. 

They wanted to serve the orders as early as possible after the order was given. The individual items in any order were served as and when all the items were ready, and the order was then considered closed. None of the items on the menu were prepared in advance in anticipation of future orders. 

On the first day, 3 groups of customers came in and ordered at 6.00 pm, 6.10 pm, and 6.13 pm. The first order was for a plate of Egg Tortillas, two plates of French Toast, and three plates of Egg Bhurji with French Fries. The second order was for a plate of French Toast and two plates of Egg Bhurji with French Fries. The third order was for a plate of Egg Tortilla and a plate of Egg Bhurji with French Fries. 

On the backdrop of the above information answer the questions given :

Question:
