Here’s a structured answer to CAT 2023 Slot 2 DILR (Data Interpretation and Logical Reasoning) questions, focusing on common question patterns and strategies. Since I don’t have access to the exact exam paper, I’ll outline a general approach with examples relevant to Indian competitive exams like CAT.
1. Data Interpretation (DI)
Common DI Formats in CAT 2023:
Caselet + Graph/Table: A narrative followed by multiple charts (e.g., sales data, population trends).
P & L Accounts or Balance Sheets: Interpreting financial statements (common in prior years).
Caselet with Multiple Diagrams: Combining flowcharts, maps, and bar graphs.
Example DI Question (Hypothetical):
A company’s sales (in Lakh ₹) for 4 quarters are given in a bar graph. The sales in Q3 were 20% higher than Q2, and Q4 sales dropped by 15% from Q3. If the total sales for the year were ₹300 Lakh, find the sales in Q1.
Solution:
Let Q2 sales = ( x ).
Q3 = ( 1.2x ), Q4 = ( 0.85 \times 1.2x = 1.02x ).
Total sales = Q1 + ( x + 1.2x + 1.02x ) = 300.
Solve for ( x ), then backtrack to find Q1.
Key Tips:
Label axes and units carefully.
Use approximation for quick calculations (e.g., 20% of 150 = 30).
2. Logical Reasoning
Common LR Topics in CAT 2023:
Seating Arrangements: Circular tables, floors, or rows with constraints (e.g., "A sits opposite to B," "C is not adjacent to D").
Picking & Placing: Assigning objects (people, items) to positions based on rules.
Blood Relations: Family tree puzzles.
Categorization: Grouping items by properties (e.g., colors, sizes).
Example LR Question (Hypothetical):
8 people (A, B, C, D, E, F, G, H) are sitting around a round table. B is seated two seats to the left of E. G is opposite to D. If A sits next to C and H, who is seated between F and H?
Solution:
Draw a circle and place D and G opposite each other.
Place B two seats left of E (e.g., B at 12 o’clock, E at 4 o’clock).
Insert A, C, H such that A is adjacent to both C and H. Remaining seat = F.
Final arrangement: F is between H and G.
Key Tips:
Draw diagrams for spatial reasoning.
Use process of elimination for constraints.
3. Game Theory (Strategy Problems)
Common Game Problems:
Resource Allocation: Distributing tasks among teams with efficiency metrics.
Path Planning: Finding the shortest route in a grid.
Scheduling: Assigning time slots without conflicts.
Example Game Theory Question (Hypothetical):
Four teams (T1, T2, T3, T4) play a tournament. Each team plays two matches. T1 must play T2 and T3. T4 cannot play T1. How many ways can the schedule be arranged?
Solution:
T1 has fixed matches: T1 vs T2 and T1 vs T3.
T4 cannot play T1, so T4’s opponents are T2 and T3.
Total matches: 4 (each team plays 2 matches).
Number of ways = 2 (T4 vs T2/T3) × 1 (remaining match) = 2 ways.
Key Tips:
Break down constraints step-by-step.
Use permutations for independent choices.
4. Key CAT 2023 DILR Trends
Real-World Data: DI questions often used recent economic data (e.g., GDP, inflation).
Simplified Language: Clarity over complexity in LR puzzles.
Time Management: 60 minutes for 40 questions (DI: 20 mins, LR: 40 mins).
Final Answer Format
For exact questions, provide the problem statement, and I’ll help solve it step-by-step. General strategies include:
DI: Focus on calculations and unit checks.
LR: Visualize and map constraints.
Games: Break problems into smaller sub-problems.
