Title: 2017 CAT DILR Slot 1 Solutions: Logical Reasoning & Data Interpretation
1. Sample Question 1 (Seating Arrangement):
Five friends (A, B, C, D, E) are sitting in a row. Conditions:
A is next to B.
C is not adjacent to D.
E is at one end.
Question: Who is sitting in the middle?
Solution:
Identify constraints:
E must be at position 1 or 5.
A and B are adjacent.
C and D cannot be next to each other.
Test possible positions:
If E is at position 1:
Remaining seats: 2, 3, 4, 5.
A and B must occupy consecutive seats. Possible pairs: (2-3), (3-4), (4-5).
Place C and D in the remaining seats, ensuring they are not adjacent.
Valid arrangement: E, A, B, D, C → Middle seat = B.
If E is at position 5:
Remaining seats: 1, 2, 3, 4.
A and B could be in (1-2), (2-3), (3-4).
Avoid C and D adjacency. Valid arrangement: E, C, A, B, D → Middle seat = A.
Conclusion:
Middle seat is B (if E is at position 1) or A (if E is at position 5).
Final Answer: B or A (context-dependent).
2. Sample Question 2 (Data Interpretation):
Sales data for 4 products (X, Y, Z, W) over 4 quarters (Q1-Q4):
Total Sales (in $M): Q1: 20, Q2: 25, Q3: 30, Q4: 35.
Growth Rate: Y grew by 15% QoQ in Q2 and Q4.
Y’s Share: Q1 = 20%, Q2 = 25%, Q3 = 30%, Q4 = 35%.
Question: What was Y’s sales in Q4?
Solution:
Calculate Total Sales for Q4: $35M.
Y’s Share in Q4: 35% → ( 35% \times 35M = $12.25M ).
Answer: $12.25 million.
Key Strategies for CAT DILR Slot 1:
Logical Reasoning:
Prioritize direct constraints (e.g., "E is at an end").
Use elimination to narrow down possibilities.
Data Interpretation:
Focus on units and percentages.
Cross-check calculations with total values.
