25+ Most Important DILR Sets for CAT 2026
DILR is one of the most unpredictable sections of the CAT exam. Practising the right DILR sets for CAT 2026 can help you improve your speed, accuracy and set-selection skills.
The CAT DILR section tests data interpretation, logical reasoning, pattern recognition and decision-making under time pressure. Regular practice with different types of CAT DILR sets will help you identify familiar patterns and choose the right sets during the exam.
In this article, you will find important DILR sets for CAT 2026, a practice PDF with solutions, key DILR topics, preparation tips and set-selection strategies.

Practising DILR from a structured collection can make your preparation more effective. Instead of randomly solving difficult sets, use a combination of easy, moderate and difficult sets to gradually improve your skills.
The CAT DILR Practice Sets PDF can be used for daily practice as well as timed revision. Try to solve each set independently before checking the solution.
For better results, do not restrict your preparation to only one type of DILR set. CAT can present familiar concepts in unfamiliar formats, so practising a variety of sets is important.
Best DILR Sets for CAT 2026
The best DILR sets for CAT 2026 are not always the most difficult. Focus on sets that improve your ability to interpret data, organise information, make logical deductions and solve questions within time.
Practise a mix of Data Interpretation (DI) and Logical Reasoning (LR) sets to build flexibility and improve set-selection skills.
| DILR Set Type | Key Skills | Difficulty |
|---|---|---|
| Tables & Charts | Data interpretation, comparison | Easy |
| Graphs | Ratios, percentages, trends | Easy-Moderate |
| Venn Diagrams | Sets, counting | Moderate |
| Arrangements | Ordering, conditions | Moderate |
| Games & Tournaments | Ranking, deductions | Moderate-Hard |
| Routes & Networks | Connections, case analysis | Hard |
| Scheduling | Sequence, conditions | Moderate-Hard |
While practising, focus on approach and set selection, not just getting the answer. Learn to quickly identify the right representation, avoid unnecessary calculations and choose the most manageable sets first.
How Many DILR Sets Should You Solve for CAT 2026?
There is no fixed number of sets that guarantees a good DILR score. Quality of practice and analysis matter more than the number of sets solved.
A good target is to solve 250–350 quality DILR sets during CAT 2026 preparation.
| Preparation Stage | Sets/Week | Focus |
|---|---|---|
| Foundation | 8–12 | Understand set types |
| Skill Building | 12–18 | Improve accuracy |
| CAT-Level Practice | 15–20 | Build speed and selection |
| Mock Phase | 12–16 | Timed practice and analysis |
| Revision | 8–12 | Review mistakes |
After every set, analyse your approach, time taken, mistakes and set-selection decision. If you get stuck, revisit the set after a few days before checking the solution.
How to Improve DILR Speed and Set Selection?
DILR speed is not just about faster calculations. Choosing the right sets can make a major difference to your CAT score.
Before solving, quickly scan the sets and look for:
- Familiar structures and easy entry points
- Fewer complicated conditions
- Manageable calculations
- Clear deductions
- Multiple questions that can be solved together
A Simple Set-Selection Strategy
Scan → Understand → Estimate → Select → Solve
Do not continue with a set just because you have already spent time on it. If you are making little progress, switch to another set and return later if time permits.
Use Efficient Representation
Organise information in the simplest possible form:
- Tables for numerical data
- Grids for distributions
- Diagrams for routes and networks
- Rankings for ordering problems
- Symbols for repeated conditions
Avoid rewriting the entire question. Use short notes, symbols and diagrams to save time and keep your rough work organised.
List of DILR Sets and Questions
Practise the following CAT-level DILR sets to improve your accuracy, speed and set-selection skills. Try solving each set yourself before checking the solution.

correct answer:- 2
A visa processing office (VPO) accepts visa applications in four categories - US, UK, Schengen, and Others. The applications are scheduled for processing in twenty 15- minute slots starting at 9:00 am and ending at 2:00 pm. Ten applications are scheduled in each slot.
There are ten counters in the office, four dedicated to US applications, and two each for UK applications, Schengen applications and Others applications. Applicants are called in for processing sequentially on a first-come-first-served basis whenever a counter gets freed for their category. The processing time for an application is the same within each category. But it may vary across the categories. Each US and UK application requires 10 minutes of processing time. Depending on the number of applications in a category and time required to process an application for that category, it is possible that an applicant for a slot may be processed later.
On a particular day, Ira, Vijay and Nandini were scheduled for Schengen visa processing in that order. They had a 9:15 am slot but entered the VPO at 9:20 am. When they entered the office, exactly six out of the ten counters were either processing applications, or had finished processing one and ready to start processing the next.
Mahira and Osman were scheduled in the 9:30 am slot on that day for visa processing in the Others category.
The following additional information is known about that day.
1. All slots were full.
2. The number of US applications was the same in all the slots. The same was true for the other three categories.

How to Practise DILR Sets
Follow this simple approach:
- Read the complete set and identify the key conditions.
- Convert the information into a table, diagram or grid wherever possible.
- Find the easiest entry point and start solving.
- Track your time and note where you get stuck.
- Note any shortcuts, mistakes or better approaches.
Avoid checking the solution immediately. Spend some time analysing the set yourself this will help you become more comfortable with unfamiliar DILR sets in CAT 2026
