Data Interpretation & Logical Reasoning is the most unpredictable section in CAT, and it often decides who clears the sectional cutoff.
DILR is entirely set-based, with 4 to 5 sets of 4 to 5 questions each; most of the sets consist of a mix of data interpretation with logical conditions.
- Solving just 2 to 2.5 sets correctly (around 6-8 questions) is enough to secure a 95+ percentile.
- The strategy to crack DILR is to solve more DILR problems. Spend the first 3-5 minutes reading through all the available sets.
- Rank the sets from easiest to hardest. Start with sets that have fewer variables or concrete data points to build quick momentum.
- During practice, focus on whether you chose the right set and exited at the right time. If you can’t progress in any particular set within 3-4 mins, leave that particular set and move on to next set.

CAT 2026 DILR Topic-Wise Weightage (Expected)
The DILR section usually consists of 22 questions, which is around 32% weightage of total exam. DILR usually has 4-5 sets with 4-5 questions from each set.
- Based on previous years' CAT paper trends, we can expect at least 4-6 questions from tables and charts alone.
- In recent years, there has been a slight increase of hybrid and complex arrangement sets.
- Focus heavily on graphs/charts, tables/caselets with conditional logics; seat arrangement usually carries significant weightage in CAT DILR.
| DILR Topics | No. of Questions (Expected) | Approximate Weightage | Important sub-topics / question types |
|---|---|---|---|
| Tables and Charts | 4-6 | 20-30% | Data tables, bar graphs, mixed sets, line graphs, pie charts |
| Games and Tournaments | 4-5 | 20-25% | Rating-based, scheduling, round-robin, Knockout |
| Scheduling and Blood Relations | 3-4 | 15-20% | Direct reasoning, task allocation, family trees |
| Venn Diagrams & Hybrid Sets | 2-3 | 10-15% | Logical deductionsSet theory |
| Puzzle and Seating Arrangements | 3-4 | 15-20% | Linear, circular, grid-based and complex arrangements |

What are the Most Repeated Topics in DILR?
Tables + conditions, Seating + distribution, games & tournaments + ranking and Graphs + logics are the most frequently asked combinations in DILR CAT sets.
- Roughly around 55-60% of DILR is based on DI, which consists of tables and graphs with conditions; these types of questions repeat almost every year.
- Around 40% of questions are based on logical reasoning, with questions mostly from arrangements and puzzles.
- Hybrid sets with DI + LR mixed have become extremely common in recent years.
- Master the tables, seating arrangements, and graphs first; they can easily cover 12-16 questions.
| Topic | Frequency (Past Years) | Frequently asked question types |
|---|---|---|
| Tables & Caselets | Very High | Most asked format in DILR CAT. Complex multi-variable tables with conditions appear almost every year. |
| Seating Arrangements (Linear, Circular, Matrix/Grid) | Very High | Repeated 7-8+ times in the last 10 years. Especially matrix & hybrid arrangements. |
| Graphs & Charts (Bar, Line, Pie, Mixed, Radar) | Very High | Core DI sets. Often combined with calculations or logic. |
| Puzzles (Grouping, Selection, Distribution) | High | Layered puzzles with multiple conditions are a CAT favourite. |
| Games & Tournaments | High | Ranking, scoring, and elimination-based sets appear consistently. |
| Scheduling & Sequencing | High | Timetables, task allocation, order & ranking with constraints. |
| Venn Diagrams & Set Theory | Medium-High | Especially 3-4 variable overlapping sets (often hybrid). |
| Routes & Networks | Medium | Path-based logical DI sets are gaining popularity. |
| Blood Relations / Family Tree | Medium | Usually appears in a hybrid puzzle format. |
| Mathematical Reasoning + DI | Medium | Ratio, percentage, calculation-heavy DI sets. |

Ques. Are Games and Tournaments sets really tough in CAT?
Ans. They can be tricky due to multiple conditions, but they are highly scoring if you understand the scoring logic. Many toppers pick them first.
CAT 2026 DILR Preparation Plan: 5-Month Strategy
If you are just starting your CAT 2026 preparation journey, 5 months is enough time to crack the DILR, which is considered to be the toughest section in CAT.
- The DILR section is the most volatile section of all in CAT; you can’t simply predict if it's going to be DI or LR-dominated paper.
- It is important to prepare equally for both DI & LR based questions; keep this in mind before you plan your DILR strategy.
- DILR requires more practice; the more you practice, the easier it becomes to recognize the patterns. The more you recognize the pattern, the easier it becomes to solve the paper.

Check Out the CAT 2026 DILR Attempt Strategy by Maruti Sir from Cracku
A CAT aspirant writes on his Medium account about his discovery about the types of DILR questions in CAT. According to him, DILR in CAT is not about solving every set, it's about choosing the right set to solve.
- He also explains DILR in CAT demands detailed structuring, high accuracy, pattern recognition and logical consistency.
- He suggests starting DILR preparation by solving a few random MCQs and puzzles; he also suggests looking at solved examples to learn the structure.

Ques. How many DILR sets should I solve daily for CAT?
Ans. Try to solve at least 3-4 quality sets daily. Focus on accuracy first, then gradually increase speed. Try to improve both accuracy and speed while solving.
How to Score 99 Percentile in DILR?
The main and important strategy to crack DILR in CAT is to choose the right set to attempt. Choose the easy to moderate sets to attempt first.
- Scan all the sets first within the first 2-3 mins and pick the set you are most confident in solving.
- If you are stuck in any set even after 3-4 mins, it's time to leave that set and move on to the next; don’t waste time.
- Solve as many DILR problems you can; the more problems you solve, the easier it becomes to recognize the patterns
- Instead of just solving mocks, spend at least 2 hours analysing your performance; note down your mistakes, errors, accuracy and attempts.
| Key Strategy | Action Steps to score 99 Percentile in DILR |
|---|---|
| Choosing the right set to attempt | Spend the first 2-3 mins scanning all sets. Pick the easiest 2-3 sets first (based on familiarity) |
| Focus more on High Accuracy | Aim for 85-95% accuracy. Avoid guesswork in tough sets |
| Conceptual understanding of topics | Prioritize: Tables/Caselets, Graphs, Seating Arrangements, Games & Tournaments |
| Solve more DILR problems | Solve 10-15 sets daily + 2-3 full sectionals/week |
| Time Management | 12-15 minutes per set. Leave 1 tough set |
| Analysing your performance after every Mock | Analyze every mock: Why was a set tough? Note patterns & mistakes |
| Revision & PYQs | Solve the last 8-10 years of CAT actual sets repeatedly |

Ques. Should I solve TITA questions first in every set?
Ans. Absolutely. No negative marking + usually easier. Many candidates lose easy marks by not attempting them.
Ques. How do I stop getting stuck on one difficult set during the exam?
Ans. Set a timer of 5-6 mins per set. If you are still stuck and not making any progress, leave that set and move on to the next one. If you still have enough time left, you can come back later.

CAT 2026 DILR Strategy: Reddit Discussions
A user on the r/CATPrep subreddit categorized every DILR question from 2021 to 2025. It shows there were 183 questions based on DI (out of 312 questions from 15 slots), which is 59% of the total questions.
- User observed that the questions based on scatter plots are now permanent; 13 questions since CAT 2021 based on scatter plots alone.
- 66 questions were purely based on logical reasoning, whereas 43 questions were from arrangements.
- The DILR section is typically not predictable; in one year, the entire paper might be of DI, and the next year might be full of LR questions.
- You can not just depend on either DI or LR. You have to focus and master both of them.
