CAT DILR Topic-Wise Weightage 2026: High-Scoring Topics, CAT 2025 Slot Analysis & Preparation Strategy

CAT 2026 DILR Expected Topic-Wise Weightage (Based on Previous Year Paper Analysis)

The CAT DILR section tests candidates on Data Interpretation and Logical Reasoning through sets like tables, charts, puzzles, and caselets. Based on previous year trends, certain topics such as arrangement puzzles, graphs, and seating arrangements appear more frequently. With CAT 2026 being held soon, aspirants must prioritise their preparation by focusing on high-weightage topics to maximise accuracy. Go through the table below to know about the CAT DILR topic wise weightage that one can expect in the upcoming examination.

Different Types of Questions Expected in CAT DILR 2026

CAT 2026 will feature a range of questions in the DILR section, designed to evaluate analytical reasoning, data interpretation, and logical thinking skills. Knowing the types of questions helps aspirants focus on high-frequency topics, manage time effectively, and improve accuracy. Below is a detailed overview of the main DILR question types along with examples.

Arrangement & Scheduling Problems

These questions require ordering people, objects, or events according to specific conditions. They test logical sequencing, prioritisation, and attention to detail.

Example:
Seven employees—A, B, C, D, E, F, and G—are to be seated in a row. A cannot sit next to B, C must be to the left of D, and F must be between E and G. Candidates must determine the possible seating arrangements satisfying all conditions.

Tabular Data Sets

Questions in this category provide information in tables and ask candidates to analyse or compute values. They test accuracy, interpretation, and basic arithmetic skills.

Example:
A table lists sales figures of five products across three months. Questions may ask:

• Which product had the highest total sales?

• By how much did Product B’s sales increase from January to March?

Candidates must extract and compare data efficiently.

Graph & Chart Interpretation

These questions present information in bar graphs, line charts, pie charts, or mixed formats, requiring candidates to interpret trends, percentages, or differences.

Example:
A line graph shows monthly production of five factories. Questions may include:

• Identify the month with the maximum production difference between Factory X and Factory Y.
  
  

• Calculate the average monthly production of Factory Z.
  
  

Graphical analysis and quick calculations are key.

Puzzles

Puzzles involve complex reasoning, often in the form of floor puzzles, grouping problems, or matrix-based arrangements. Candidates must logically eliminate impossible options to reach the correct solution.

Example:
Four friends—P, Q, R, and S—like different sports: Tennis, Football, Badminton, and Cricket. Q doesn’t like Tennis or Cricket. R likes a sport with a ball. Who plays which sport?

Such questions test stepwise reasoning and elimination skills.

Caselets

Caselets are short passages containing multiple data points and often interrelated information. They require candidates to combine logic, arithmetic, and data interpretation to answer several sub-questions.

Example:
A company produces three types of gadgets: X, Y, and Z. Each gadget requires different hours of labour and materials. The caselet provides constraints on production capacity and demand. Questions may ask:

• Maximum number of Z gadgets producible in a week.

• Total labour hours needed if certain production targets are met.

Candidates must carefully extract relevant information to solve multiple queries.

Logical Reasoning Sets

These questions test deductive, inductive, and critical reasoning. Candidates analyse statements, assumptions, or conclusions to arrive at correct answers.

Example:
Statements:

• All managers are decision-makers.

• Some decision-makers are not analysts.

Questions may ask:

• Can we conclude that some managers are not analysts?

• Which of the following statements must be true?

CAT 2026 Important Topics for DILR

The key topics in DILR for the CAT 2026 examination can be shortlisted by properly analysing the CAT previous year question papers. The candidates can make the best use of the remaining time for their CAT 2026 preparation by understanding the most important DILR sets for CAT and learning them first. Careers360 have conducted a proper analysis of the previous year CAT question papers and has shortlisted a set of the most important DILR sets for CAT. They are listed below:

In the CAT 2025 examination, 9 CAT DILR questions were asked in slots 1 and 3 under the logical reasoning section of the CAT DILR 2025 examination. 10 questions were asked under slot 2 of the CAT DILR section’s logical reasoning topic. This collectively constitutes 45% of the total CAT DILR section. Some of the important topics that the candidates should take care of under the CAT Logical Reasoning section are:

Games and Tournaments

While analysing the CAT DILR previous year topics, it was observed that 2 sets of the CAT DILR section were solely focused on the games and tournaments topic. The first five questions of the CAT 2025 slot 1 examination were based on the games and tournament set. The difficulty level of this question was moderate. In the same manner, the last five questions of the CAT 2025 slot 2 examination were also asked from the games and tournaments topic. Due to the frequency with which the questions are repeating from the games and tournaments topics in the recent CAT examinations, the games and tournaments topic becomes one among the most important DILR sets for CAT.

Routes and Networks

Similar to the games and tournaments topic, 10 questions were collectively asked from both the CAT DILR slots 1 and 2, marking one of the key topics in DILR for CAT 2026. Going by the previous year's CAT question paper analysis, it can be observed that the candidates can expect a question from the routes and networks topic in the CAT 2026 examination. The questions asked under the routes and networks concepts are generally slightly more lengthy and hence, the candidates must prepare well for this section.

Logical Arrangement and Ordering

Among all the logical reasoning CAT 2026 topics, the logical arrangement and ordering topic is one of the most probable CAT DILR topics 2026 that is sureshot for the CAT 2026 examination. This is mainly because, under this topic, questions can be asked from topics such as:

• Linear Arrangements.

• Circular Arrangements

• Distribution questions

• Selection questions

• Ordering questions

Since there are a lot of possibilities of questions that may be asked in the logical arrangement and ordering section, this is a very important CAT DILR topic and must be prioritised during the candidate’s CAT DILR preparation.

Quantitative Aptitude-based Logical Reasoning

Quant-Based Logical Reasoning in CAT involves reasoning problems that are grounded in numerical and mathematical logic. These sets often include topics like number series, age problems, time and work, time-speed and distance, clocks, calendars, and puzzles involving mathematical operations. Unlike pure logic-based sets, these require candidates to apply arithmetic concepts along with logical thinking to arrive at the correct answers. They test both quantitative aptitude and the ability to deduce patterns or sequences logically under time pressure.

Most Important Data Interpretation CAT 2026 Topics

The CAT previous year analysis indicates that the greatest weightage of the CAT DILR section is given to the Data Interpretation section. One of the key data interpretation CAT 2026 topics that the candidates can expect in the CAT 2026 examination is a question on graphs. Similarly, there are a few most important DILR sets for CAT that the candidates should be aware of. The most important CAT DI topics are listed below after a thorough analysis of the CAT's previous year question papers.

Graphs

Questions on graphs cannot be overlooked during the candidate’s DILR preparation. Graph questions are a must in the CAT examinations. While various types of graph questions may be asked in the CAT examination, a set of questions from the topic is confirmed. Some of the topics from which the candidates can expect questions under the graph concepts include:

• Bar Charts

• Line Graphs

• Pie Charts

• Mixed Graphs (Bar + Table, Pie + Line)

• Spider/Radar Charts

• Scatter Plots.

In the CAT 2025 examination, the graphical questions were asked from topics such as line charts, bar graphs and candlestick charts. 4 questions were asked from each slot of the CAT 2025 examination under the graph topic. The candidates can secure 12 marks in the CAT examination with efficient graph preparation. Hence, topic graphs are one among the most important DILR sets for CAT and should be prioritised during the data interpretation section preparation of the candidates.

Table-Based Data Interpretation

Table-based DI questions appeared in slot 3 of the CAT 2025 examination. The candidates were asked a total of 4 questions under this topic. While it may not be as frequently asked topic as the graphs, there is a good chance that the table-based DI questions may appear in the CAT 2026 examination. Hence, the candidates are advised to solve the various questions of the table-based DI topic to enhance their CAT DI preparation.

Quant-Based Data Interpretation

The Quant-based DI questions are very frequently asked under the Data Interpretation section of various management entrance examinations. Quant-Based Data Interpretation in CAT involves numerical data given to candidates where they must apply mathematical concepts like ratios, percentages, and averages to analyse and answer the questions accurately. The data presented to the candidates can be in a graph, table or even passages. This type of question assesses the quantitative reasoning skills of the candidates along with their attention to detail. Making it one of the favourite CAT DILR topics 2026 for the examiners.

Common Mistakes to Avoid in CAT DILR Sections

The CAT DILR section (Data Interpretation and Logical Reasoning) looks tough for many students. Most of the time, it is not about how much you know, but about avoiding small mistakes. If you know these mistakes in advance, you can save time, stay calm, and get a better score.

1. Spending Too Much Time on One Set

Many students keep trying one hard puzzle for 20 minutes. This wastes time and reduces attempts. Remember: all sets have the same marks. If one set feels too tough, leave it and try an easier one.

2. Not Choosing the Right Sets

Some students start solving the first set they see. This is risky. Always spend 2–3 minutes at the beginning to check all sets. Pick the ones that look clear and simple first.

3. Slow or Weak Calculations

In DI, you need to calculate fast. If you depend only on long methods, you will lose time. Learn quick tricks for percentages, ratios, averages, and approximations. This saves minutes in the exam.

4. Misreading Data or Rules

One small mistake in reading a table, chart, or puzzle rule can make the whole answer wrong. Read the question slowly. Underline or write down key conditions before you start solving.

5. Running After Speed, Forgetting Accuracy

Some students try to solve too many sets in less time. But wrong answers give negative marks. It is better to solve fewer sets correctly than many sets with mistakes.

6. Not Checking Mistakes in Mock Tests

Many candidates just take mock tests and move to the next one without checking errors. This is a big mistake. Always check where you went wrong and write it in an “error notebook.” This helps you avoid the same mistakes again.

CAT DILR Questions Difficulty Level Over the Years

The CAT DILR section has changed a lot over the years in terms of question style and difficulty. From long calculation-based DI sets to logical puzzles and unconventional caselets, the focus has shifted to testing smart thinking, data handling, and time management rather than pure mathematics.

Before 2015

DILR was mixed with Quant. Most questions were calculation-heavy DI sets like tables, bar graphs, and pie charts. Logical reasoning had basic seating arrangements and puzzles.

2015–2019

DILR became a separate section with 32 questions. Difficulty went up sharply. DI had more reasoning-based caselets instead of direct calculations. LR included games, tournaments, and complex arrangements. Many students found it the toughest section.

2020–2022 (Pandemic Pattern)

The number of questions reduced to 24. Still, the section was tricky because most sets needed deep logical thinking. Direct DI questions almost disappeared.

2023–2026

CAT DILR had 20 questions in 40 minutes. Sets were fewer but tougher. Choosing the right 2–3 sets was key. Most were reasoning-based puzzles like Venn diagrams, distribution, and hybrid sets.

Trend in 2026

CAT DILR continues to test smart selection. You don’t need to solve all sets—just pick the doable ones and solve them with accuracy. The focus is on logical clarity, not speed alone.

CAT Data Interpretation Preparation Tips

Now that the candidates have almost 6 months for CAT preparation, they should begin by practising the important topics of each section by following the effective CAT 2026 preparation strategies. Some of the necessary CAT DILR preparation tips that can be followed by the candidates to enhance their preparation are listed below.

• Focus on understanding different types of DI sets like tables, bar graphs, pie charts, and caselets. The candidates should solve as many CAT 2026 DILR sample questions as possible.

• Practice calculations involving percentages, ratios, and averages to improve speed and accuracy.

• Develop the ability to quickly interpret data and spot trends or inconsistencies.

• The candidates should work on their approximation skills to save time during lengthy calculations.

• Solve previous year CAT DI questions to get familiar with the exam pattern and difficulty level.

• Attempt sectional tests and mock exams regularly to improve time management.

Best Approach to Solve CAT DILR 2026 Questions

To perform well in CAT 2026 DILR, candidates must focus on clarity and logic rather than speed alone. DILR questions in CAT 2026 are data-heavy and time-bound, so a structured solving approach is critical. Smart set selection, clean data arrangement, and logical elimination help reduce mistakes and improve efficiency. Using the right CAT DILR strategy allows aspirants to maximize attempts while maintaining high accuracy.

Smart Set Selection

In CAT 2026 DILR, the first and most important step is selecting the right set. Spend the initial 2–3 minutes scanning all DILR sets and assessing the number of variables, conditions, and questions. Sets with limited entities, direct data, and fewer layered conditions are generally easier. Avoid sets requiring excessive calculations or multiple assumptions, as they consume time and increase error probability.

Clear Data Representation

Proper data representation is essential for solving CAT DILR questions accurately. Convert long textual information into tables, grids, Venn diagrams, or flowcharts based on the set type. Well-organised data reduces repeated reading and helps identify patterns, gaps, and forced placements quickly. A clean layout also ensures smoother logical deductions during CAT 2026 DILR practice.

Use Constraints First

All CAT 2026 DILR sets are driven by constraints. Start by applying fixed constraints such as exact values, absolute positions, or strict comparisons. These high-impact conditions instantly eliminate invalid possibilities. Once strong constraints are applied, move to relative or conditional constraints to refine the arrangement further. This approach keeps logic controlled and efficient.

Reduce Unnecessary Cases

Many CAT DILR aspirants lose time by creating too many cases. Only introduce case analysis when constraints clearly demand it. Even then, limit cases to mutually exclusive possibilities. Always test a case quickly against all key conditions—if it fails early, discard it. Case reduction keeps CAT 2026 DILR sets manageable.

Solve Question-Driven

Instead of completing the entire set, read the questions early and identify which data points are actually required. Several CAT DILR questions can be answered using partial information. Targeted solving helps save time and mental effort, which is crucial in the high-pressure CAT 2026 exam environment.

Quick Logical Checks

After every key deduction, perform quick logical checks to ensure consistency with given data. Cross-verify values with original constraints to avoid cascading errors. These small checkpoints help maintain accuracy, especially in lengthy CAT 2026 DILR sets where one mistake can affect multiple answers.
