CAT DILR Important Topics 2026
The CAT DILR section rewards candidates who can interpret information, identify relationships and choose the right sets under time pressure. Unlike Quant, DILR does not have a rigid chapter-wise CAT DILR syllabus. A single set may combine arrangements, rankings, distribution and numerical calculations, which makes topic labels useful for preparation but not absolute.
An analysis of CAT DILR questions from 2021 to 2025 across all three slots shows some clear recurring areas. Graphs and charts, arrangements, distribution/ allocation, quantitative reasoning, games and tournaments, and rankings have collectively contributed a substantial share of DILR questions during this period.
Therefore, CAT 2026 aspirants should prioritise high-frequency set structures while still practising a sufficiently diverse mix of DILR problems.
CAT DILR Section Overview 2026
DILR is primarily a set-selection and reasoning section. CAT 2021–2023 had 20 DILR questions per slot, while CAT 2024 and CAT 2025 had 22 questions per slot. Across the three slots, this translates to 60 questions annually from 2021–2023 and 66 questions annually in 2024–2025.
A useful distinction is that CAT does not always separate Data Interpretation and Logical Reasoning cleanly. A graph-based set may require considerable deduction, while an arrangement problem may contain numerical data and percentage calculations.
This explains why preparation based only on conventional topic labels can be limiting. Aspirants should instead learn how to represent information, identify constraints, make deductions and compare data quickly.
Important Logical Reasoning Topics for CAT 2026
The five-year trend indicates that arrangements, distribution/allocation, games and tournaments, networks, rankings and scheduling deserve particular attention for CAT 2026.
Arrangements
Arrangements, ordering and grouping contributed 44 questions across CAT 2021–2025. Aspirants should practise linear and circular arrangements, grouping, ordering and multi-variable arrangements.
Games & Tournaments
Games, tournaments and competition-based sets accounted for 29 questions over the five years. These can involve wins and losses, points tables, rankings, round-robin competitions and incomplete results.
Rankings
Ranking and rating sets contributed 25 questions between 2021 and 2025. Their importance has also been visible recently, with 9 such questions classified in CAT 2025.
Scheduling and Sequencing
Scheduling and sequencing accounted for 19 questions in the five-year data. These sets typically involve assigning events, people or activities to different days, periods or positions.
Distribution and Allocation
Distribution, allocation and matching are particularly important, contributing 31 questions across the five years. These problems frequently overlap with arrangements and grouping.
Networks and Routes
Network, route and diagram-based LR contributed 28 questions between 2021 and 2025. CAT can use routes, connections or relationships between entities to test deduction in an unfamiliar format.
Puzzles and Sequencing
Puzzle-based reasoning does not always appear as an independent category because puzzles frequently combine arrangements, rankings, distribution and sequencing. Aspirants should therefore practise unfamiliar mixed-condition sets instead of relying only on standard puzzle formats.
Important Data Interpretation Topics for CAT 2026
The five-year data makes graphs, charts and quantitative DI particularly important areas for CAT 2026 preparation.
Bar Graphs, Line Graphs and Other Charts
Graph and chart-based sets form the largest category in the supplied five-year classification, accounting for 56 questions from 2021 to 2025. CAT 2024 and CAT 2025 alone contributed 17 and 16 questions respectively.
Students should practise bar graphs, line graphs, mixed graphs and unconventional chart formats.
Tables and Missing Data
Tables, missing-data sets and tabular DI accounted for 23 questions during the five-year period. These sets can involve multiple variables, incomplete values and relationships that must be established before calculation.
Caselets
Caselet DI presents information through text rather than a ready-made chart. The first task is often converting the information into a table, grid or other structured representation.
Ratios and Percentages
Ratios and percentages should be treated as supporting calculation skills rather than isolated DILR chapters. They regularly appear inside graphs, tables and quantitative DI sets.
Data Comparison
CAT DI often rewards comparison and approximation instead of lengthy exact calculations. Candidates should become comfortable comparing ratios, percentage changes, averages and relative values quickly.
Quant and Number-Based DI-LR
Quantitative and number-based LR/DI contributed 42 questions across CAT 2021–2025, making it another major recurring category. Strong arithmetic fundamentals can therefore directly improve DILR performance.
CAT DILR Topic-wise PYQs
DILR improves through repeated exposure to unfamiliar sets. Recent CAT 2025 analysis found Logical Reasoning at about 59% of DILR questions, with mixed DI-LR caselets and pure DI forming the remaining share.
CAT DILR Topic-Wise Questions: 2025–2021
The following table combines CAT DILR questions across all three slots for each year and classifies them into broad set types.
Broad Topic / Set Type | 2025 | 2024 | 2023 | 2022 | 2021 | 5-Year Total |
Arrangements / Ordering / Grouping | 9 | 9 | 10 | 10 | 6 | 44 |
Games & Tournaments / Competitions | 4 | 5 | 5 | 5 | 10 | 29 |
Scheduling / Sequencing | 5 | 0 | 5 | 5 | 4 | 19 |
Distribution / Allocation / Matching | 8 | 4 | 10 | 5 | 4 | 31 |
Networks / Routes / Diagram-Based LR | 4 | 9 | 5 | 10 | 0 | 28 |
Tables / Missing Data / Tabular DI | 4 | 4 | 0 | 5 | 10 | 23 |
Bar/Line/Other Graphs & Charts | 16 | 17 | 5 | 10 | 8 | 56 |
Rankings / Ratings | 9 | 5 | 5 | 0 | 6 | 25 |
Quant/Number-Based LR & DI | 7 | 9 | 15 | 5 | 6 | 42 |
Other Caselets / Hybrid DI-LR | 0 | 4 | 5 | 5 | 6 | 20 |
Total DILR Questions | 66 | 66 | 60 | 60 | 60 | 312 |
Important: The individual topic totals overlap because some DILR sets can reasonably be classified under more than one broad skill or set type. Therefore, the topic rows should not be added together to derive the total number of DILR questions. The annual totals represent the actual number of questions across the three CAT slots.

CAT DILR Topic-Wise Weightage and Previous Year Trends
The 2021–2025 data provides useful preparation signals, but it should not be interpreted as a fixed CAT DILR weightage.
The following trends are particularly useful:
Graphs and charts have been highly prominent recently. The category increased from 5 questions in 2023 to 17 in 2024 and 16 in 2025. This makes graph interpretation an important preparation area, but it does not guarantee similar representation in CAT 2026.
Arrangements have shown greater consistency. Arrangement, ordering and grouping sets contributed between 6 and 10 classified questions every year in the five-year data. This consistency makes arrangements one of the foundational LR areas worth mastering.
Distribution and quantitative reasoning frequently overlap with other set types. Distribution/allocation recorded 31 questions, while quantitative/number-based LR and DI recorded 42. Rather than treating these as isolated chapters, aspirants should develop the ability to use numerical reasoning inside different set structures.
Games, rankings and networks are also significant. Their representation varies considerably from year to year, illustrating exactly why CAT DILR preparation should not be based on predicting a narrow set of topics.

High-Weightage CAT DILR Topics for 2026
Based on the 2021–2025 trend, aspirants can use the following priority framework for preparation:
Preparation Priority | Topics to Focus On | Why? |
Core Focus | Graphs & Charts | 56 classified questions across five years; particularly prominent in 2024–25 |
Core Focus | Arrangements / Ordering / Grouping | 44 questions and consistent presence across all five years |
Core Focus | Quant/Number-Based LR & DI | 42 questions and applicable across multiple types of sets |
High Priority | Distribution / Allocation / Matching | 31 questions and frequently overlaps with arrangements |
High Priority | Games & Tournaments | 29 questions across five years |
High Priority | Networks / Routes | 28 questions, although year-to-year frequency varies |
Important | Rankings / Ratings | 25 questions, including 9 in 2025 |
Important | Tables / Missing Data | 23 questions and an important basic DI format |
Important | Caselets / Hybrid Sets | 20 questions and useful for unfamiliar DILR structures |
Important | Scheduling / Sequencing | 19 questions with recurring appearances |
This table should be used to decide practice priority, not what to skip. CAT can change its set mix significantly from one year to another. For example, networks had no classified questions in 2021 but 10 in 2022, while scheduling went from 5 questions in 2023 to none in 2024 and back to 5 in 2025.
CAT DILR Preparation Tips to Maximize Your Score in 2026
A strong CAT DILR preparation strategy should combine high-frequency topics with diverse set exposure.
Start with arrangements, graphs/charts and quantitative DI-LR because the five-year data indicates both high frequency and broad applicability. Then build strength in distribution, games and tournaments, networks, rankings, tables and scheduling.
Do not, however, divide your preparation strictly according to historical question counts. A better approach is to practise mixed DILR sets every day so that you learn to recognise structures without knowing the topic beforehand.
CAT DILR PYQs should form an important part of this process. After solving every set, ask three questions: Was this the right set to select? What was the key breakthrough? Could I have represented the information more efficiently?
Finally, follow a structured CAT DILR preparation strategy by gradually moving from untimed practice to CAT sectional tests and CAT mock test. In the actual exam, knowing how to solve a difficult set is only one part of DILR performance. The more valuable skill is identifying which available sets can be solved accurately within the available time.
The 2021–2025 data ultimately points towards one preparation principle: prioritise recurring structures, but prepare for unpredictability. CAT may change the context, presentation and combination of concepts, but candidates who are comfortable with arrangements, graphs, numerical reasoning, distribution and other recurring structures will have a stronger foundation for handling unfamiliar CAT 2026 DILR sets.

CAT DILR Important Topics 2026: Conclusion
The CAT DILR Important Topics 2026 analysis shows that graphs and charts, arrangements, quantitative DI-LR, distribution, games and tournaments, networks and rankings deserve consistent attention during preparation. However, previous-year weightage should not be treated as a prediction of the CAT 2026 paper because the type and combination of DILR sets can change considerably from year to year.
Aspirants should use these trends to prioritise practice while continuing to solve diverse DILR sets, PYQs, sectional tests and mocks. Along with mastering individual topics, focus on set selection, efficient data representation and identifying the key deduction quickly. The strongest CAT DILR strategy is to prepare for recurring structures without becoming dependent on a predictable paper pattern.
