Title: CAT 2018 Slot 2 QA - Solutions & Analysis for Indian Game-Related Questions
Introduction
The CAT (Common Admission Test) 2018 exam included a mix of Verbal, Reading Comprehension, Quantitative Ability (QA), and Data Interpretation & Analysis (DIA) questions. While specific "game-related" questions aren’t explicitly documented in public CAT papers, we can infer common QA and logical reasoning patterns that align with strategic decision-making or rule-based scenarios, often framed as "games." Below is a generalized guide to solving such problems, along with sample solutions inspired by typical CAT 2018 themes.
1. Sample Game-Related QA Question (Hypothetical)
Question:
A game involves moving a token on a 4x4 grid. The token starts at the top-left corner. At each step, the player can move right or down. However, if a move leads to a cell containing a 'Z', the token is blocked. How many valid paths are there from start to finish?
Solution:
Grid Setup:
(0,0) → (0,1) → (0,2) → (0,3)
| | | |
(1,0) → (1,1) → (1,2) → (1,3)
| | | |
(2,0) → (2,1) → (2,2) → (2,3)
| | | |
(3,0) → (3,1) → (3,2) → (3,3)
Assume cells (0,2) and (1,1) contain 'Z'.
Approach:
Use dynamic programming (DP) to count valid paths while avoiding blocked cells.
Calculations:
Path to (0,1): 1 (only right).
Path to (1,0): 1 (only down).
Path to (0,3): Sum of paths to (0,2) [blocked] + (0,1) → 0 + 1 = 1.
Path to (3,3):
From (3,2): 1 path (right).
From (2,3): 1 path (down).
Total = 1 + 1 = 2.
Answer: 2 valid paths.
2. Key CAT 2018 QA Trends
Combinatorics & Permutations:
Questions often involved optimizing paths (e.g., avoiding obstacles) or distributing items under constraints.
Example: "In how many ways can 5 people be seated in a row if A and B must not sit adjacent?"
Probability & Game Strategies:
Hypothetical games with win/loss conditions or probability matrices.
Example: "A game has 3 rounds. The probability of winning each round is 0.6. What’s the probability of winning at least 2 rounds?"
Data Interpretation (DIA):
Games could be framed as interpreting tables/charts (e.g., tournament brackets, scores).
3. Strategic Tips for CAT QA
Master Dynamic Programming: For path-counting and optimization problems.
Practice Combinatorics Shortcuts: Use combinations (nCr) and permutations (nPr) for grouping problems.
Time Management: QA questions are time-sensitive; avoid overcomplicating logic.
4. Final Notes
While exact CAT 2018 "game-related" questions aren’t publicly available, the above examples reflect common QA themes. For precise solutions, share the specific question or type of game logic involved.
