Understanding CAT LRDI

The LRDI section usually consists of 20–24 questions, divided into 5–8 sets. Each set contains 4–6 interlinked questions based on questions like case studies, graphs, charts, or logical puzzles. To solve such questions, you will have to draw logical conclusions. Apart from practicing topics like these, you will have to practice time management as well, so that you can solve these complicated questions in time.

Unlike traditional sections, LRDI has no defined syllabus, but the types of questions generally revolve around seating arrangements and puzzles, Venn diagrams and set theory, data tables, bar graphs, line charts, pie charts, games and tournaments, and network or route-based problems. To get a better understanding, try solving the CAT exam's previous year's question paper.

The real challenge is not to solve every question but to be able to solve every question on time. Practicing previous years’ question papers will give you a rough idea of what to expect in the exam and which topics you need to focus on more so that you can enhance your rank and score.

Now. Let’s go through the various challenges faced by the students and what the possible solutions are for them.

Challenges Faced by Students

While preparing for a highly competitive exam like CAT, it is inevitable that you will not face any challenges. Before finding the solution, let’s take a look at possible problems faced by the students while solving CAT mock test papers.

1.      Unpredictability: LRDI questions vary in structure and syllabus, which confuses students a lot.

2.      Time Consumption: Some sets are lengthy and require deep analysis before solving. So, a time limit per question won’t work.

3.      Pressure: Choosing the wrong set can waste valuable exam minutes.

4.      Lack of Shortcuts: No universal formula works for all sets.

CAT mock test papers help you to identify where your efforts are lacking. If you take these mock tests consistently, you will see a positive growth in your preparation, which ultimately means a better score, a better rank, and a seat in the college of your choice.

Now, let’s move to the tricks and strategies to prepare smartly for the CAT.

1.  Set Selection

You might think that you can solve every set since you’ve prepared for the exam so well. In fact, to score better than most of the aspirants, you will need to pick and choose your sets.

This table might help you to choose better.

2. Structured Approach to Solve the Exam

To solve the questions correctly, confidently, and accurately, you will have to follow a structured approach. We are laying down the recommended expert strategy to solve questions in an organized way so that you don’t end up losing precious time in exams.

• Read the questions carefully and understand what is being asked.

• Extract the data: meaning write it down in table or diagram form.

• Identify constraints and mark relationships, inequalities, or conditions.

• Data can be overwhelming, but try to solve it calmly.

• The final step is to ensure no contradiction arises or your answer makes sense. 

3.  Practice visualizations for tables and diagrams

The majority of LRDI problems require a table, Venn diagram, graph, or some kind of data representation for you to solve the question. If you practice enough to visualize these tables, you will save yourself from a lot of effort and complications in the actual exam.
To learn this efficiently, we recommend you learn from the experts' recommended CAT preparation books. For instance,

1.      Use tables for arrangement and distribution problems.

2.      Use Venn diagrams for set theory-based questions.

3.      Use charts or grids for scheduling, tournaments, and allocation problems.

To simplify more, let’s understand how you can solve a seating arrangement problem quickly and without much effort.

If you learn to represent or visualize data in a tabular form, questions can become less intimidating.

4. Approximations in DI

You need to learn and identify questions where accuracy is not required. For instance, questions involving pie charts can be estimated, or an approximate percentile may suffice. If your options differ by large margins, you can use the approximation method, or you can also use the elimination method to identify the right choice. It will save you much-needed time. 

5. Time Management Strategy

On average, each set requires 8–10 minutes. You should aim to solve 4 sets with high accuracy to secure a good percentile.
Let’s go through how experts recommend time allocation for the LRDI section.

6. Accuracy vs. Speed

You might get tempted to solve every question before the exam time ends. But remember it is the accuracy that counts. Every wrong answer mark will reduce your percentile and push you away from your goal.

• Mark answer only if you are 70-80% sure.

• Skip if you are confused, to not waste time. 

7. Practice mental calculations

The CAT exam is not all about solving every complex problem. It is about being able to solve one of them on time. Data interpretation often revolves around calculations, graphs, ratios, and averages. Learn to multiply, divide, add, and subtract big numbers in your mind. It will make you sharp and fast.
