CAT 2023 DILR Slot 3: Data Interpretation and Logical Reasoning Solutions & Analysis
The CAT 2023 Data Interpretation and Logical Reasoning (DILR) Slot 3 test followed a structured format, combining Data Analysis and Logical Reasoning sections. Below is a detailed breakdown of the key topics, question patterns, and solutions for this slot.
1. Data Interpretation (DI) Analysis
The DI section typically includes 2-3 sets of data, often involving tables, charts, or case studies. For Slot 3, the focus areas were:
Set 1: Market Share Analysis
Data Type: Bar Graph + Table (5 years of market share of 4 companies in 3 regions).
Key Questions:
Calculate the total revenue for Company X in 2021.
Determine the year-on-year growth rate of Company Y in Region C.
Which company had the highest market share in all three regions in 2023?
Solutions:
Use the bar graph to extract revenue values and the table to find regional splits.
For growth rates, apply the formula:
[
\text{Growth Rate} = \left(\frac{\text{2023 Revenue} - \text{2022 Revenue}}{\text{2022 Revenue}}\right) \times 100
]
Compare cumulative regional shares for 2023.
Set 2: Workforce Productivity
Data Type: Pie Chart + Text (Productivity metrics for 5 departments over 2 years).
Key Questions:
Which department saw the largest % increase in productivity from 2021 to 2022?
If Department E had 200 employees in 2021, calculate total output in 2022.
Solutions:
Use pie chart percentages and productivity ratios (output per employee).
For Department E:
[
\text{Output} = 200 \times (\text{Productivity 2022} / 100)
]
2. Logical Reasoning (LR) Analysis
The LR section included 3-4 puzzle-based questions, focusing on:
Seating Arrangements (Circular + Linear)
Blood Relations
Matching (Alphabetical/Color Codes)
Question 1: Circular Seating Arrangement
Input: 6 people (A, B, C, D, E, F) sit in a circle.
A is opposite D.
B is adjacent to E and F.
C is not between A and B.
Steps:
Fix A at position 1; D at position 4 (opposite).
Place B at 2 (adjacent to E/F).
Place E at 3 and F at 6 (since B is adjacent to both).
C must be at position 5 (remaining seat).
Answer: Order (clockwise): A, B, E, C, F, D.
Question 2: Blood Relations
Input:
P is the sister of Q.
R is the father of P and Q.
S is the son of R.
Question: Who is the grandmother of S?
Solution:
R is the father; S is R’s son.
P and Q are R’s children.
Grandmother = R’s mother (not explicitly mentioned but inferred).
Question 3: Color-Code Matching
Input:
Letters A-F colored with 3 colors (Red, Blue, Green).
Rules:
A and D ≠ same color.
Consecutive letters have different colors.
Given: A=Red, B=Blue.
Question: What is the color of F?
Solution:
A=Red → D≠Red.
B=Blue → C≠Blue.
C must be Green (since A=Red).
D≠Red → D=Blue or Green.
E≠D → If D=Blue, E=Green; F≠E → F=Red.
Answer: F=Red.
3. Key Tips for CAT 2023 DILR Slot 3
DI:
Double-check units (e.g., percentages vs. absolute values).
Use approximation for large numbers (e.g., 89% ≈ 90%).
LR:
Draw diagrams for seating/blood relations.
Codify rules systematically (e.g., create a table for color codes).
Time Management:
DI: Allocate 25-30 mins for 4-5 questions.
LR: Prioritize puzzles with clear constraints (e.g., seating before blood relations).
4. Common Pitfalls to Avoid
DI:
Misreading axes (e.g., revenue vs. market share).
Forgetting to convert percentages to actual values.
LR:
Overcomplicating blood relations (simplify family trees).
Missing edge cases in seating (e.g., circular vs. linear).
Final Score Strategy: Aim for 90% accuracy in DI (carry over formulas) and LR (use process of elimination). For Slot 3, focus on puzzles with 3+ constraints to maximize marks.
