CAT 2024 Slot 2 DILR Solutions
Here’s a structured analysis and solutions for the Data Interpretation & Logical Reasoning (DILR) section of CAT 2024 – Slot 2. This guide includes key strategies, common patterns, and step-by-step explanations for typical DILR questions.
1. Data Interpretation (DI)
Caselet Analysis / Table Reading
Key Steps:
Skim the caselet to identify variables (e.g., cities, products, years).
Create a mental framework using relationships and constraints.
Translate data into equations for quick calculations.
Example Question (Hypothetical):
“A company sells products A, B, and C in four cities (X, Y, Z, W). In 2023, sales in City X were 20% higher than in City Y. Product C contributed 35% of total sales in City Z. If total sales in City W were ₹50 lakh, what is the ratio of Product B sales in City Y to Product A sales in City X?”
Solution:
Note variables: Cities (X, Y, Z, W), Products (A, B, C), Year (2023).
Key ratios:
X = 1.2Y (20% higher than Y).
C in Z = 35% of Z’s total.
W’s total = ₹50 lakh.
Answer: Use substitution or ratio manipulation based on given data.
Data Visualization (Charts/Graphs)
Common Types: Bar graphs, pie charts, line graphs, heatmaps.
Strategy:
Compare trends: Focus on relative changes (e.g., % increase/decrease).
Identify outliers: Look for anomalies in data points.
Use benchmark values: Cross-check with hypotheticals (e.g., “If 2024 sales were 10% higher, what would be the total?”).
Example (Hypothetical):
“A line graph shows monthly revenue (in ₹ lakh) for 6 months. Which month had the highest % drop in revenue compared to the previous month?”
Solution:
Calculate month-over-month % change:
Formula: [(Current Month – Previous Month)/Previous Month] × 100.
Compare all values to identify the maximum negative % change.
2. Logical Reasoning (LR)
Seating Arrangement / Floor Plan
Steps:
List constraints: Positions (left/right), directions (north/south), relationships (e.g., "A sits opposite to B").
Assign tentative positions using process of elimination.
Verify consistency with all given conditions.
Example Question (Hypothetical):
“Six people (P, Q, R, S, T, U) are seated around a circular table. S sits opposite to U. T is to the immediate right of R. Q is not adjacent to S. Who sits between P and T?”
Solution:
Draw a circle. Place S and U opposite each other.
Place R and T (T is right of R).
Place P and Q such that Q is not adjacent to S.
Final arrangement: P, R, T, U, Q, S (clockwise).
Answer: P and T are separated by R.
Puzzle / Blood Relations
Key Tips:
Tree diagrams: Visualize family hierarchies.
Matrix method: Tabulate relationships (e.g., parent-child, marital status).
Example (Hypothetical):
“A family has four generations. Each person has two children. If the youngest generation has 3 members, how many members are there in total?”
Solution:
Generations: Grandparents (2) → Parents (4) → Children (6) → Grandchildren (3).
Total: 2 + 4 + 6 + 3 = 15.
Matching / Odd One Out
Strategies:
Group elements by common properties (e.g., odd/even, prime/composite).
Eliminate options systematically.
Example (Hypothetical):
“Which of the following is the odd one out? A) 17, B) 21, C) 25, D) 27, E) 29”
Solution:
Prime numbers: 17, 29 (others are composite).
Answer: B) 21, C) 25, D) 27.
3. Visual Reasoning (VR)
Common Types:
Pattern recognition: Grids, sequences, rotations.
Mirror images: Reflective symmetry.
Paper folding: Determine resultant figure.
Example (Hypothetical):
“A 3×3 grid has shapes (circle, square, triangle). The pattern alternates between shapes and shading. What is the missing shape in the bottom-right corner?”
Solution:
Observe rows/columns: Alternate shapes (circle → square → triangle).
Shading: Alternate between filled and unfilled.
Answer: Unfilled triangle.
4. Key Takeaways
Time management: Allocate 45–60 minutes for DILR.
Practice mental math: Speed up calculations with shortcuts (e.g., percentages, ratios).
Check for consistency: Ensure all constraints are satisfied in LR solutions.
