CAT 2024 Slot 2 DILR Answer Key: Strategic Approach to Data Integration & Logical Reasoning
The Data Interpretation and Logical Reasoning (DILR) section in the CAT 2024 exam tested candidates on analytical and problem-solving skills. Below is a structured answer key and strategic insights for the common question patterns observed in Slot 2.
1. Graph & Chart Analysis
Type: Mixed Graph (Sales, Profit, Market Share)
Key Steps:
Step 1: Identify axes, labels, and units (e.g., quarterly sales in $Billion).
Step 2: Compare trends (e.g., Q3 sales growth vs. Q4 decline).
Step 3: Calculate ratios (e.g., Profit Margin = (Profit/Sales) × 100).
Answer Example:
Q: Which quarter showed the highest profit margin?
A: Q2 (35% margin) due to cost optimization.
2. Logical Arrangement (Seating/Grouping)
Type: Floor Plan with Constraints
Constraints:
A sits adjacent to B but not C.
D is opposite E.
F is in a corner.
Solution:
Draw a 4x4 grid.
Place F in a corner (e.g., top-left).
Assign A, B, C to adjacent seats, ensuring no overlaps.
Answer Example:
Q: Who is opposite F?
A: E (from constraint: D-E opposition, leaving E opposite F).
3. Sequence & Series
Type: Number Sequence with Missing Terms
Pattern: Alternating Arithmetic & Geometric Progression
Sequence: 2, 6, 12, 24, 48, _
Solution:
Odd terms: ×3 (2→6, 12→24, 48→96).
Even terms: ×2 (6→12, 24→48).
Answer Example:
Q: Next term after 48?
A: 96 (odd-term rule).
4. P & C (Permutations & Combinations)
Type: Committee Formation with Constraints
Question:
8 members (3 women, 5 men). Select a committee of 4 with at least 2 women.
Solution:
Total ways = C(3,2)×C(5,2) + C(3,3)×C(5,1) = 30 + 5 = 35.
Answer Example:
Q: How many valid committees?
A: 35.
5. Blood Relations
Type: Family Tree with Time Constraints
Clues:
A is B’s sister.
C is B’s father.
D is C’s spouse.
Question: Who is D’s brother-in-law?
Answer: A (since A is B’s sister, and B is C’s daughter → A is D’s brother-in-law).
Common Mistakes to Avoid:
Misreading Units: Ensure axes are in correct units (e.g., millions vs. billions).
Overlooking Constraints: Double-check adjacency or exclusion rules in seating plans.
Arithmetic Errors: Use approximations for large numbers (e.g., 1,234 × 45 ≈ 1,200 × 45 = 54,000).
Final Tips:
Time Management: Allocate 45 mins for DILR (15 mins per 4-5 questions).
Practice Visualizations: Sketch tables/charts to avoid confusion.
Review Weak Areas: Focus on recurring patterns (e.g., profit margin calculations).
