CAT DILR 5-Year Trend Analysis (2021-2025): Topic-Wise Weightage, Sets and Difficulty

CAT DILR Five-Year Trend Analysis: 2021 to 2025

The DILR section has seen a noticeable change in its structure over the last five CAT editions. From 20 questions across four sets in 2021-2023, CAT moved to 22 questions across five sets in 2024 and 2025. The number of questions per set has also varied, making set selection an important part of the section.

CAT DILR Topic-Wise Trends

The CAT DILR section does not follow a fixed topic-wise distribution every year. Instead, the exam combines different types of Data Interpretation and Logical Reasoning sets, often presenting familiar concepts in unfamiliar formats. The five-year trend from 2021 to 2025 shows recurring appearances of CAT DILR questions based on arrangements, games and tournaments, tables, charts, networks, routes and distribution-based sets.

Data Interpretation Trends

Data Interpretation sets in CAT have continued to test candidates on their ability to extract relationships from tables, graphs, charts and caselet-based information. Recent papers have also combined numerical data with logical conditions, making some sets require both calculation and deduction.

Across 2021 to 2025, candidates encountered DI based on:

• Tables and caselets

• Bar and line graphs

• Data comparison

• Ratios and percentages

• Revenue, cost and profit-based information

• Rankings and ratings

• Multi-variable datasets

The trend shows that DI is not limited to direct calculation. Candidates often need to identify the relevant information first and then perform calculations or comparisons.

Logical Reasoning Trends

Logical Reasoning has covered a wide range of set formats rather than relying on one fixed question type. Arrangements, rankings, grouping, games, tournaments, networks and scheduling-based sets have appeared across different CAT editions.

Many LR sets provide several conditions that must be combined to arrive at the answer. As a result, understanding the relationship between the given conditions is as important as applying a particular LR technique.

Arrangement-Based Sets

Arrangement-based questions have remained a recurring part of CAT DILR. These sets can involve people, objects, teams, positions, schedules or other entities that need to be arranged according to multiple conditions.

Common variations include:

• Linear arrangements

• Circular arrangements

• Ordering and sequencing

• Ranking

• Position-based conditions

• Scheduling and placement

The format may change from one year to another, but the underlying requirement remains the same: convert the information into a workable arrangement and eliminate possibilities systematically.

Games and Tournaments

Games and tournament-based sets have appeared in several CAT papers and can combine matches, points, wins, losses, rankings and performance conditions. Questions may require candidates to determine possible outcomes, rankings or missing information from the data provided.

These sets generally require careful tracking of multiple conditions rather than straightforward calculation. Candidates may also need to construct a table or maintain possible cases while solving the set.

Tables and Charts

Tables and charts form an important part of the DI component. CAT has used bar graphs, line graphs, tables and other graphical representations to present information that candidates must compare or interpret.

Questions can involve:

• Percentage change

• Ratios

• Maximum and minimum values

• Comparisons between categories

• Missing data

• Trends across different periods

• Combined information from more than one variable

The five-year trend also shows that a chart-based set may include a logical element, so candidates should practise interpreting the information before beginning calculations.

Networks and Routes

Networks and routes involve connections, paths, movement and relationships between different points. These sets may be presented through diagrams or schematic representations and can require candidates to trace possible routes or determine relationships between connected elements.

The difficulty often comes from translating the given information into a clear visual representation before answering the questions.

Distribution-Based Sets

Distribution-based sets require candidates to allocate people, objects, resources, tasks or other entities according to specified conditions. They may involve grouping, selection, allocation or multiple restrictions.

Typical conditions can include:

• Minimum or maximum allocation

• Fixed group sizes

• Conditional selection

• Inclusion or exclusion rules

• One-to-one distribution

• Multiple possible arrangements

These sets are useful for analysing the broader LR trend because they test whether candidates can manage several constraints simultaneously rather than relying on direct formula-based solving.

CAT DILR Question Type Trends

Across CAT 2021 to 2025, CAT DILR 5 years sets has largely remained set-based, but the nature of questions within those sets has varied. The five-year papers show a mix of calculation-heavy DI, condition-based LR, caselets, arrangements, routes and hybrid DI-LR sets. The table below captures the actual question formats reported across the papers rather than treating every DILR question as a separate standalone type.

CAT DILR Topic-Wise Weightage: 2021 to 2025

The exam has not followed a fixed CAT DILR chapter-wise weightage. The paper is organised around sets, and the same broad topic can appear in different forms across slots and years. A five-year comparison shows repeated appearances of arrangements, games and tournaments, tables, graphs, networks, distribution and hybrid DI-LR sets. The table below consolidates the reported slot-wise papers from CAT 2021 to CAT 2025.

Five-Year Topic-Wise Distribution

What Changed and Remained Same in CAT DILR in Five Years?

The CAT DILR section changed in its question count, set structure and the way DI and LR concepts were combined between 2021 and 2025. At the same time, the section continued to rely on set-based problem solving, with arrangements, tables, charts, games, networks, distribution and caselet-style questions recurring across the period.

What Changed in CAT DILR?

CAT DILR Preparation Strategy Based on Five-Year Trends

The 2021-2025 CAT papers show that DILR preparation needs to cover both recurring set formats and unfamiliar combinations of DI and LR. The section moved from 20 questions in four sets to 22 questions in five sets in 2024, while arrangements, games, tables, graphs, distribution, networks and caselets continued to appear across different papers.

Building Set Selection Skills

Set selection can be practised and measured using previous CAT papers.

Maintain a record of sets selected, sets rejected, reason for rejection, time spent and questions eventually solved. This helps identify whether time is being lost on lengthy or unsuitable sets.

Practising Different Set Types

The five-year CAT dataset contains recurring formats such as arrangements, games and tournaments, tables, graphs, distribution, routes, networks and caselets. A useful practice mix is:

The percentages are practice targets, not CAT weightage.

Improving Calculation Speed

Track calculation time separately from total set-solving time.

For every DI set, record reading time + calculation time + reasoning time. This makes it easier to identify whether calculation or interpretation is causing delays.

Handling Difficult Sets

Use a three-level classification after every practice session:

Do not count an incomplete difficult set as a successful attempt. Record why it remained unsolved, complex conditions, excessive calculations, incorrect setup, wrong interpretation or time pressure.

Analysing DILR Mocks

A mock analysis should record more than the final score.

CAT 2026 DILR: What the Five-Year Trend Suggests

The CAT 2021-2025 DILR papers show a clear shift in section size and set presentation, but not a fixed topic-wise pattern. DILR increased from 20 questions in 2021-2023 to 22 questions in 2024 and 2025. The five-year PYQ analysis covers 66 sets and 312 questions, with arrangements, games and tournaments, distribution, tables/charts, routes/networks, scheduling, caselets and mixed DI-LR sets recurring across the papers.
