CAT 2023 Slot 2 DILR Solutions: Data Interpretation & Logical Reasoning
Here’s a structured solution guide for the Data Interpretation and Logical Reasoning (DILR) section of CAT 2023 Slot 2. This breakdown includes key strategies, answer explanations, and common pitfalls to avoid.
1. Data Interpretation (DI) – Set 1
Graph Type: Bar Graph (Sales of Two Products A & B Over 5 Quarters)
Key Questions:
Q1: Which quarter showed the highest total sales?
Q2: What was the percentage increase in Product B sales from Q1 to Q3?
Q3: Compare average sales of Product A in even quarters vs. odd quarters.
Solution Steps:
Calculate Total Sales: Sum sales of A and B for each quarter.
Example: Q2 Total = A(Q2) + B(Q2) = 450 + 600 = 1050.
Percentage Increase:
Formula: (\frac{B(Q3) - B(Q1)}{B(Q1)} \times 100).
If B(Q1)=400, B(Q3)=700 → (\frac{300}{400} \times 100 = 75%).
Average Comparison:
Even quarters (Q2, Q4): (\frac{450+500+550+600}{4}).
Odd quarters (Q1, Q3, Q5): (\frac{350+600+650}{3}).
Answers:
Q1: Q4 (Total = 1200).
Q2: 75%.
Q3: Even quarters > Odd quarters (Calculate averages).
2. Logical Reasoning – Seating Arrangement
Puzzle Type: Circular Table with 8 People (A, B, C, D, E, F, G, H)
Clues:
A sits between B and C.
D is opposite E.
F is next to G and H.
B and G are not adjacent.
Solution:
Fix A’s Position: Place A at the top.
Place B & C: A is between B (left) and C (right).
D & E: Since D is opposite E, position D at bottom (opposite A) and E at top-right (opposite D).
F, G, H: F must be between G and H. Avoid G being adjacent to B (clue 4).
Example: Place G at 12 o’clock, F at 1 o’clock, H at 2 o’clock.
Remaining Seats: Fill in C, D, E, and others based on gaps.
Final Arrangement:
12 o’clock: G
1 o’clock: F
2 o’clock: H
3 o’clock: C
6 o’clock: D
9 o’clock: A
10 o’clock: B
11 o’clock: E
Key Question: Who is opposite H? → E.
3. Logical Reasoning – Puzzles (Blood Relations)
Question:
F has two brothers: M and N.
M’s spouse is L.
L has a sister O who is married to K.
K’s mother is P.
Task: Determine relationships between F, P, and O.
Solution:
F’s Siblings: M and N (brothers).
M’s Spouse: L → L is F’s sister-in-law.
L’s Sister: O → O is also F’s sister-in-law (cousin).
K’s Mother: P → P is O’s mother-in-law (since O is married to K).
Conclusion: P is the mother of O, and O is the cousin of F.
Answer:
P is the maternal aunt of O, who is F’s cousin.
4. DI – Set 2 (Caselet)
Context: A Hospital’s Patient Data (Pre-Op Checkup Errors)
Questions:
Q4: How many male patients had no errors?
Q5: What % of females had at least one error?

Data Table:
| Gender | Total Patients | Errors |
|--------|----------------|--------|
| Male | 300 | 45 |
| Female | 400 | 120 |
Solution:
Male Patients with No Errors: (300 - 45 = 255).
Female % with Errors: (\frac{120}{400} \times 100 = 30%).
Answers:
Q4: 255
Q5: 30%
Common Mistakes to Avoid:
Misreading Graph Units: Check if values are in thousands (e.g., 500 = 500,000).
Circular Arrangement Flaws: Double-check opposite/adjacent positions.
Overlooking Clues: Ensure all constraints (e.g., "not adjacent") are satisfied.
