Title: CAT 2023 Slot 3 Difficulty Level: Game-Based Questions and Solutions
Content: English-Indian Exam Preparation Guide
Introduction
The CAT (Common Admission Test) 2023 exam featured a challenging slot 3 with a focus on game-based logical reasoning and data interpretation questions. This guide provides detailed solutions and strategies for tackling high-difficulty game-related problems, tailored for Indian aspirants.
Key Game-Based Question Types in CAT 2023 Slot 3
Seating Arrangement with Constraints
Example Question:
*"Six friends—A, B, C, D, E, F—sit in a row. Each person belongs to one of three clubs: X, Y, or Z. Conditions:
A and B are in different clubs.
C and D are adjacent but not in the same club.
E and F are in club X.
How many valid arrangements are possible?"*
Solution:
Clubs Assignment: E and F are fixed in Club X. Assign A, B, C, D to Clubs Y/Z with constraints.
Constraints Breakdown:
A ≠ B (different clubs).
C and D are adjacent but different clubs.
Valid Arrangements:
Fix E and F in positions 1 and 6 (or vice versa).
For A, B, C, D: 2 choices (Y/Z) for A, 1 choice for B (opposite of A), 2 choices for C and D (adjacent with opposite clubs).
Total arrangements = 2 (E/F positions) × 2 (A/B) × 2 (C/D) = 8.
Grouping and Allocation
Example Question:
"12 employees are divided into three teams (T1, T2, T3) of 4 each. T1 must have 2 engineers and 2 managers. T2 must have at least 3 engineers. How many ways can this be done?"
Solution:
Step 1: Select 2 engineers and 2 managers for T1.
Engineers: C(6,2) = 15.
Managers: C(6,2) = 15.
Total for T1: 15 × 15 = 225.
Step 2: Assign remaining 4 engineers and 4 managers to T2 and T3.
T2 must have ≥3 engineers. Possible splits:
T2: 3 engineers + 1 manager; T3: 1 engineer + 3 managers.
T2: 4 engineers; T3: 0 engineers + 4 managers.
Calculate combinations for each split and sum.
Total Ways: 225 × [C(4,3)×C(4,1) + C(4,4)×C(4,0)] = 225 × (16 + 1) = 3,600.
Data Interpretation with Game Logic
Example Question:
"A survey ranks 10 candidates (P1–P10) in three categories: Innovation, Efficiency, and Teamwork. Each category has no ties. A candidate is a ‘top Performer’ if they rank 1st in ≥2 categories. How many top performers are possible?"
Solution:
Possible Cases:
A candidate ranks 1st in 2 categories and any rank in the third.
A candidate ranks 1st in all 3 categories.
Calculations:
For each candidate: C(3,2) ways to choose 2 categories to lead.
Total = 10 × 3 = 30.
Subtract overlaps (candidates leading all 3 categories): 10.
Final Answer: 30 – 10 = 20.
Strategies for CAT 2023 Game-Based Questions
Break Down Constraints: List all conditions (e.g., adjacency, exclusion) and visualize them.
Use Combinatorics: Apply combinations (C(n,k)) and permutations (P(n,k)) systematically.
Leverage Pigeonhole Principle: For allocation problems (e.g., ensuring minimum engineers in a team).
Practice with Real slot 3 papers: Time-bound drills to improve speed.
Conclusion
CAT 2023 slot 3 emphasized logical rigor and analytical precision in game-based questions. Mastering combinatorics, constraint analysis, and data interpretation is critical for high difficulty levels. Aspirants should practice past papers and focus on optimizing step-by-step reasoning.
Preparation Tip: Use mock tests to simulate exam conditions and refine time management.
