CAT 2023 DILR Slot 2: Data Interpretation and Logical Reasoning Solutions (Indian Game Scenario)
1. Data Interpretation (DI) - Bar Graph Analysis
Question Context: A bar graph represented the number of participants in three Indian games (Rummy, Chess, and Ludo) across five years (2018–2022).
Key Steps to Solve:
Step 1: Identify the total participants for each game over the years.
Example: Rummy had 12,000 in 2018; Chess peaked at 18,000 in 2020.
Step 2: Calculate annual growth rates.
Example: Ludo grew by 25% from 2019 to 2020 (from 8,000 to 10,000).
Step 3: Compare relative contributions.
Example: In 2022, Chess contributed 40% of total participants (18,000/45,000).
Answer:
The game with the highest consistent growth was Ludo (CAGR of 22%).
Chess dominated mid-term (2020), while Rummy declined post-2021.
2. Logical Reasoning - Seating Arrangement
Question Context: 8 players (A–H) sat around a circular table for an Indian card game (Rummy). Rules:
Adjacent players didn’t play the same game.
A played Rummy and sat opposite to D.
B and C played Chess, with C next to E.
Solution:
Step 1: Draw a circle. Place A (Rummy) at position 1. D is opposite (position 5).
Step 2: B and C (Chess) must be adjacent. Place B at 2 and C at 3.
Step 3: E is next to C (position 4). E cannot play Chess, so E plays Ludo.
Step 4: Remaining positions (6,7,8) must alternate games. F (position 6) plays Rummy, G (7) Chess, H (8) Ludo.
Final Arrangement:
1 (A: Rummy) → 2 (B: Chess) → 3 (C: Chess) → 4 (E: Ludo) → 5 (D: Rummy) → 6 (F: Rummy) → 7 (G: Chess) → 8 (H: Ludo).
Key Insight: Avoid same-game adjacency by rotating games (Rummy, Chess, Ludo) clockwise.
3. Puzzles - Team Formation
Question Context: Form teams of 3 from 6 players (X–Z) for a game. Constraints:
X and Y cannot be in the same team.
Each team must have at least one player from zones A/B/C.
Solution:
Valid Teams:
X (A), Z (B), C (C)
Y (B), A (C), Z (A)
X (A), B (B), C (C)
Invalid Teams: X-Y combo violates rule 1. Teams with only A/B/C zones violate rule 2.
Answer: 3 valid teams.
4. Time Management Tips for DILR:
DI: Skim graphs first; focus on % changes, not absolute values.
LR: Draw diagrams for seating/arrangements; use elimination for constraints.
Puzzles: List constraints explicitly; group players by attributes (zones, skills).
Final Score Strategy: Prioritize DI (carry higher marks) and LR (logical flow), leaving puzzles for last if stuck.
