Title: 2022 CAT DILR Slot 1: Data Interpretation and Logical Reasoning Solutions & Strategies
Introduction
The 2022 CAT DILR Slot 1 (Data Interpretation and Logical Reasoning) featured a mix of passage-based data interpretation and logical reasoning questions. Here’s a breakdown of key strategies, solved examples, and common pitfalls to avoid.
1. Data Interpretation (DI) Focus
Key Topics: Caselet Analysis, Table Reading, and Graph Interpretation.
Strategy:
Skim the passage: Identify variables (e.g., sales, profit, time) and relationships (e.g., % change, ratios).
Create mental frameworks: Use tables or quick sketches to map data (e.g., monthly sales vs. expenses).
Answer direct questions first: Avoid overcomplicating with irrelevant details.
Example Question:
A company’s monthly sales (in ₹ crores) and expenses (in ₹ lakhs) for Q1 2022 are given in a table. Calculate the profit % for March if the company’s fixed costs are ₹50 lakh.
Solution:
March Sales: ₹120 crore = ₹12,000 lakh
March Expenses: ₹75 lakh (given) + ₹50 lakh (fixed) = ₹125 lakh
Profit: ₹12,000L - ₹125L = ₹11,875L
Profit %: (11,875 / 12,000) × 100 ≈ 98.96%
2. Logical Reasoning (LR) Tips
Key Topics: Sequence & Series, Blood Relations, Puzzles (Seating Arrangements, Floor Plans).
Strategy:
Visualize problems: Draw Venn diagrams, flowcharts, or floor plans.
Test constraints: Use "must be true" vs. "could be true" logic.
Time management: Skip ambiguous questions; revisit them later.
Example Puzzle:
8 people (A–H) are seated in a circle. A sits between B and C. D is opposite E. F is next to G. Who is opposite H?
Solution:
Arrange known pairs: A-B-C-A (clockwise).
Place D-E opposite: D opposite E → positions 5 & 1 (if A is 1).
F-G adjacency: Remaining spots (positions 3,4,6,7). Assign F-G to 3-4 or 6-7.
Opposite H: If H is at 8, opposite is 2 (C).
3. Common Mistakes to Avoid
Overcounting/undercounting: Verify totals (e.g., 12 people in a group → 11 pairs).
Ignoring "at least" vs. "exactly": Read keywords carefully.
Mishandling percentages: Convert all values to the same unit (e.g., ₹ to lakh).
4. Time Allocation Plan
DI: 40 mins (20 mins per passage)
LR: 35 mins (15 mins for puzzles, 10 mins for sequences)
Review: 10 mins to check arithmetic errors.
Final Tips:
Practice past CAT papers (2018–2021) to熟悉题型.
Use official mock tests for slot timing.
Focus on accuracy over speed in DI; prioritize LR puzzles.
Good luck with your CAT preparation! 🚀
