Here’s a structured English guide to CAT 2023 Slot 1 DILR (Data Interpretation & Logical Reasoning) with key strategies, question types, and solutions:
CAT 2023 Slot 1 DILR: Key Focus Areas
Data Interpretation (DI)
Graphs/Charts: Time-based (GDP, Sales), Comparative (Market Share), and Composition (Pie Charts).
Tables: Missing value calculations, trend analysis, and ratio comparisons.
Caselet DI: Mixed data (e.g., production, costs, profits) with multiple questions.
Logical Reasoning (LR)
Sequences & Puzzles: Alphabets, numbers, symbols, and real-life scenarios (e.g., seating arrangements).
Blood Relations & Cubes: Complex family trees and 3D cube rotations.
Assumption/Causation: Drawing logical conclusions from statements.
Grouping & Matching: Pairing items based on given criteria.
Sample DI Question & Solution
Question:
A table shows monthly sales (in ₹ Lakhs) of three products (A, B, C) over 6 months. Answer:
What was the average sales of Product C in months 3-5?
If Product B’s sales in June were 20% higher than May, what was the total sales in June?
Solution:
Calculation:
Sum = 85 + 90 + 95 = 270
Average = 270 / 3 = ₹ 90 Lakhs
Given: May B = ₹ 80L, June B = 80 * 1.2 = ₹ 96L
Total June Sales = A (₹ 75L) + B (₹ 96L) + C (₹ 100L) = ₹ 271L
Logical Reasoning Tips
Sequences: Look for patterns (e.g., +2, ×3, alternating).
Puzzles: Create grids for seating/cube rotations; mark constraints first.
Blood Relations: Draw family trees step-by-step; avoid assumptions.
Time-Saving: Skip 3-4 lengthy LR questions; prioritize DI.
Common CAT DILR Errors
Overlooking Units: Convert % to decimals or vice versa.
Miscalculating Averages: Use total/number instead of adding averages.
Misinterpreting Puzzles: Failing to update constraints after each step.
Neglecting Time Limits: DI questions often take 2-3 mins; practice speed.
Preparation Strategy
Mock Tests: Focus on Slot 1 patterns (e.g., 2022 Slot 1 had 2 DI sets of 4 questions each).
Previous Year Analysis: 2022 DILR had 24 questions (12 DI, 12 LR).
Tools: Use online simulators (e.g., Testbook, VMock) for timed practice.
Key Resources:
Books: MAT Data Interpretation by R.S. Aggarwal

Final Checklist
✅ Practice 3-4 DI sets daily.
✅ Solve 2 LR puzzles daily (focus on sequences and puzzles).
✅ Review mistakes in mock tests.
✅ Manage time: DI (35 mins) + LR (25 mins).
