The DILR section sets are often hybrid, combining data from charts/tables with complex logical conditions. The following are the most important topics to prepare.
Logical Reasoning tests your ability to structure information and deduce conclusions based on a set of restrictive conditions.
Logical Reasoning Key Topics | ||
LR Topic Category | Question Type | Focus Area |
Arrangements & Puzzles | Linear, Circular, and Complex Seating Arrangements | Placing people/objects according to conditions like "X sits next to Y but not opposite Z." |
Distribution/Grouping Puzzles | Distributing items (e.g., subjects, cities) among people/groups based on multiple constraints. | |
Floor & Building Puzzles | Assigning people to different floors or buildings with conditional rules. | |
Games & Tournaments | Round-Robin and Knockout Formats | Calculating ranks, scores, or outcomes of matches based on given results and rules. Often involves maximizing/minimizing scores. |
Logic Puzzles | Truth/Lie (Binary Logic) | Determining who is speaking the truth (Knights) and who is lying (Knaves) based on contradictory statements. |
Routes & Networks (Graph Theory) | Finding the minimum/maximum cost, time, or number of routes between nodes/cities. | |
Scheduling | Allocating events, shifts, or projects across a timeline with fixed constraints. |
Data Interpretation sets ask you to take out, determine, and compare data given in different forms. Have a look at the key topics for this section.
Data Interpretation (DI) Key Topics | ||
DI Topic Category | Question Type | Details |
Venn Diagrams | 2-Set, 3-Set, and 4-Set Overlapping Data | Calculating the number of elements in intersections, unions, and complements (e.g., people who read exactly one, exactly two, or none of three magazines). |
Caselets/Tables | Missing Data Tables | Finding unknown values in a table using interdependent percentages, ratios, or averages. |
Caselets with Hybrid Data: | Data presented in a paragraph format, often involving Arithmetic topics like Percentages, ratios, and Average-based calculations. | |
Chart-Based DI | Complex Chart | Interpreting and combining data from non-traditional charts (e.g., Radar/Spider Charts, Bubble Charts, Stacked Bar Charts). |
Quantitative DI | Sets heavily integrated with concepts from Quantitative Aptitude (Time, Speed, Distance; Time and Work; Mixtures; Profit & Loss). |
Given below are some CAT DILR questions. Candidates can practice such questions to hone their logical and analytical skills.
Direction (1 - 5) Read the following passage and answer the given questions.
Five friends Aman, Pankaj, Manav, Kiran, and Ranjeet each arrived at a crowded
parking lot in their individual cars. When they reached, they found exactly twenty cars already parked in a single row of slots. Since they were in a hurry, they managed to adjust and park their cars in different positions within the existing row by shifting a few of the already parked cars. No other vehicle entered or exited the lot after they parked, so the total number of cars in the row now are twenty-five. The following clues describe the relative positions of their cars after all five had parked:
Q1 How many cars are parked to the right of Kiran's car?
Q2 How many cars are parked between Ranjeet’s car and Manav’s car?
(A) 14
(B) 10
(C) 5
(D) Cannot be Determined
Q3 How many cars are parked to the right of Manav’s car?
Q4 Between which of the following pairs of friends' cars are the maximum number of
cars parked?
