Title: 2018 Slot 2 DILR: Game-Based Data Interpretation and Logical Reasoning Solutions
Category: Competitive Exams (CAT, XAT, GMAT) | Focus: Logical Reasoning & Data Interpretation
Introduction
The 2018 CAT (Common Admission Test) exam featured a DILR (Data Interpretation and Logical Reasoning) section in Slot 2 (afternoon session). This section often includes game-based scenarios, such as team formations, rule-based puzzles, or data-driven decision-making tasks. Below is a structured analysis of potential game-related questions and their solutions, aligned with typical DILR patterns from that year.
1. Game-Based Data Interpretation Example
Scenario:
“A board game involves 8 players divided into two teams of 4. Each team earns points based on moves. The following table shows the points scored by each player in a match. Determine the team with the highest average score and the player with the maximum contribution to their team’s total.”
Data Table:
| Player | Team | Points |
|--------|------|--------|
| A | Team 1 | 30 |
| B | Team 1 | 25 |
| C | Team 1 | 20 |
| D | Team 1 | 15 |
| E | Team 2 | 28 |
| F | Team 2 | 22 |
| G | Team 2 | 18 |
| H | Team 2 | 12 |
Steps to Solve:
Calculate Total and Average Scores:
Team 1 Total = 30 + 25 + 20 + 15 = 90
Team 2 Total = 28 + 22 + 18 + 12 = 80
Team 1 Average = 90 / 4 = 22.5
Team 2 Average = 80 / 4 = 20
Conclusion: Team 1 has a higher average.
Identify Top Player Contribution:
Team 1: Player A (30 points) contributes 30/90 = 33.3%
Team 2: Player E (28 points) contributes 28/80 = 35%
Answer: Player E contributes the most to Team 2’s total.
Key Takeaway:
Use arithmetic operations (sum, average, percentages) to interpret tabular data.
Highlight critical metrics like averages, totals, and individual contributions.
2. Logical Reasoning Example
Scenario:
“In a game, 8 friends (A, B, C, D, E, F, G, H) play a round-robin tournament. Each pair plays exactly once, and no two pairs play on the same day. On which day does pair (G, H) play if the following conditions are met?”
Given Conditions:
A plays B on Day 1.
C plays D on Day 3.
E and F play on consecutive days.
G and H play on the last day.
Solution:
Total Matches: For 8 players, total matches = ( \binom{8}{2} = 28 ).
Each day has 4 matches (since ( 28 / 7 = 4 )).
Assign Days Based on Conditions:
Day 1: A vs B, and 3 other matches.
Day 3: C vs D, and 3 other matches.
Consecutive Days for E vs F: Assume Day 2 and 3, but conflict with C vs D on Day 3. Hence, E vs F must be on Days 4-5 or 5-6.
Last Day (Day 7): G vs H.
Logical Deduction:
E vs F cannot be on Days 2-3 due to overlap.
Assign E vs F to Days 5-6.
Remaining days fill in other matches.
Answer: Pair (G, H) plays on Day 7.
Key Takeaway:
Use combinatorial logic and constraint-based elimination.
Track overlaps and prioritize fixed conditions (e.g., G vs H on the last day).
3. Tips for Game-Based DILR Questions
Data Interpretation:
Identify key metrics (total, average, ratio) quickly.
Use图表 (graphs/tables) to visualize trends.
Logical Reasoning:
List all constraints explicitly.
Create timelines or matrices for scheduling problems.
Time Management:
Allocate 35-40 minutes for DILR (50 questions).
Tackle data-heavy questions first, then logic puzzles.
Conclusion
The 2018 Slot 2 DILR likely tested game-based scenarios requiring data analysis and logical deduction. Mastery of arithmetic, combinatorial logic, and constraint-solving is critical. Practice similar questions to improve speed and accuracy.
Final Answer Format (for mock questions):
Question 1: Team 1 (Average: 22.5)
Question 2: Day 7
