Title: DILR Slot 3 CAT 2024: Strategic Guide for Data Interpretation & Logical Reasoning
The DILR (Data Interpretation and Logical Reasoning) section in the CAT 2024 exam will include Slot 3, which typically focuses on logical reasoning, critical reasoning, and data analysis. Here’s a detailed guide to tackle this slot effectively:
1. Key Topics to Prioritize
Data Interpretation (DI):
Graphs/Charts: Time-series, bar graphs, pie charts.
Tables: Missing value calculations, percentage comparisons.
Caselets: Multi-step analysis, inference-based questions.
Logical Reasoning:
Puzzles: Seating arrangements, blood relations, box-packing.
Coded语言: Direction sense, blood relations, logical syllogisms.
Critical Reasoning: Assumption-based questions, conclusion traps.
2. Time Management Tips
DI (20-25 mins):
Skim charts for key metrics (e.g., highest/lowest values).
Use approximations to save time (e.g., 23.6% ≈ 24%).
LR (25-30 mins):
Solve puzzles in order of complexity (e.g., start with seating, then blood relations).
Create visual maps for relationships or sequences.
3. Sample DI Question (CAT 2023 Pattern)
Question:
A survey of 500 students’ preferences for extracurricular activities is shown in a pie chart. What is the ratio of students preferring sports to those preferring music?
Solution:
Calculate sports percentage: 35% of 500 = 175 students.
Music percentage: 20% of 500 = 100 students.
Ratio = 175:100 = 7:4.
4. LR Puzzles: Step-by-Step Approach
Example:
8 people (A-P) are seated around a circular table. Some constraints:
A sits opposite D.
B and C are adjacent.
E is not between F and G.
Solution:
Draw a circle and place A and D opposite each other.
Place B and C next to each other (positions 2 and 3).
Place E such that it’s not between F and G (e.g., position 5).
Fill remaining seats (H, I, J) with remaining letters.
5. Common Pitfalls to Avoid
Overcomplicating LR: Simplify constraints into bullet points.
Ignoring Units in DI: Convert percentages to actual numbers.
Rushing into Assumption Questions: Always validate conclusions with the stem.
6. Practice Resources
Books: Crack the CAT by Arun Sh向东, Logical Reasoning for CAT by Meenakshi Upadhyay.
Mock Tests: CAT 2023 slot papers, mocks from TCS, Hindu.
Tools:
Excel: For quick table calculations.
Logic Grids: Use online templates for LR.
7. Final Strategy for CAT 2024
Mock Analysis: Identify recurring weak areas in Slot 3.
Previous Year Trends: 60% DI + 40% LR in recent CATs.
Stay Updated: Check official CAT 2024 notification for any rule changes.
Good luck with your preparation! 🚀
