Here’s a structured analysis and solution guide for CAT 2017 LRDi Slot 2 (Logical Reasoning & Data Interpretation), tailored for Indian entrance exam preparation. This format aligns with common CAT question patterns and emphasizes clarity for aspirants.
CAT 2017 LRDi Slot 2: Key Topics & Approach
1. Data Interpretation (DI) Section
Theme: Mixed Quantitative Data (Table + Graph)
Sample Question Type:
Interpret a table showing annual sales of 5 brands (A-E) across 4 years (2013-2016), with % growth rates and market share changes. Calculate:
Q1: Year and brand with the highest absolute growth in sales.
Q2: % change in market share of Brand C from 2013 to 2016.
Solution Strategy:
Step 1: Tabulate data and highlight growth rates vs. absolute values.
Example: Brand E showed 18% growth in 2016 (highest %), but Brand A had higher absolute growth due to larger base sales.
Step 2: Use market share formula: (Sales of Brand / Total Market Sales) × 100.
Calculation: For Brand C, if sales grew from ₹10M to ₹14M, and total market grew from ₹100M to ₹140M, market share % = (14/140) × 100 = 10% (vs. 10% in 2013).
Common Pitfall: Confusing % growth with % change in market share. Always cross-verify with total market trends.
2. Logical Reasoning (LR) Section
Theme: Circular Arrangement + Blood Relation
Sample Question:
A, B, C, D, E, F are seated around a circle. B is between A and C. D is opposite E. F is next to A. Who is opposite C?
Solution Framework:
Draw a circular diagram with 6 positions.
Place fixed points:
A-B-C (clockwise or counter-clockwise).
D opposite E → E opposite D.
F adjacent to A → F can be at position 6 (if A is at 1).
Assign remaining positions:
Positions: 1 (A), 2 (B), 3 (C), 4 (D), 5 (E), 6 (F).
Opposite C (position 3) is position 6 → F.
Key Tip: Use process of elimination and symmetry in circular arrangements.
3. Time Management Tips
DI: Allocate 20 mins/2 questions. Focus on tables-charts first (higher marks per minute).
LR: Solve family tree/sequence questions early ( Often fewer steps but higher difficulty).

5. Post-Exam Analysis
DI Strengths: Master reading tables quickly and calculating % changes.
LR Weaknesses: Practice family tree diagrams and positional keywords (e.g., "opposite," "adjacent").
