CAT 2023 LRDI Slot 2: Comprehensive Guide and Solutions
Prepared for Indian aspirants preparing for the Common Admission Test (CAT)
CAT 2023 LRDI (Logical Reasoning, Data Interpretation, and Diagrammatic Reasoning) Slot 2 typically includes 20 questions across three sections:
Logical Reasoning (8 questions)
Data Interpretation (8 questions)
Diagrammatic Reasoning (4 questions)
Below is a structured analysis of potential question patterns, solved examples, and key strategies for LRDI Slot 2.
1. Logical Reasoning (LR)
Key Topics:
Blood Relations
Seating Arrangements
Puzzles (Alphabets, Numbers, Cities)
Statements & Conclusions
Categorization
Sample Question 1:
“A, B, C, D, E, F are six people standing in a row. A is next to B, but not next to C. D is between E and F. If A is at one end, how many possible arrangements are there?”
Solution:
Positioning A: A can be at the left end (1st) or right end (6th).
B’s Position: Since A is next to B, B is either 2nd or 5th.
D, E, F: D must be between E and F. Possible sequences: EDF or FED.
Combine Constraints:
If A is 1st, B is 2nd. Remaining positions (3-6) must accommodate C, D, E, F.
D must be between E/F. For positions 3-6:
EDF (positions 3-5) or FED (positions 3-5).
C occupies position 6.
Total arrangements: 2 (EDF/FED) × 2 (A at ends) = 4.
Key Takeaway: Visualize arrangements using grids or flowcharts.
2. Data Interpretation (DI)
Key Topics:
Caselet DI (Story-based Data)
Table/Graph Analysis
Missing Data Calculation
Sample Question 2:
“The table below shows the sales (in ₹ lakh) of four products (X, Y, Z, W) in two years (2022 and 2023). Calculate the percentage increase in sales of product Z in 2023 compared to 2022.”
Product
2022
2023
X
120
150
Y
90
108
Z
150
180
W
200
220
Solution:
Sales of Z in 2022: ₹1,50,00,000
Sales of Z in 2023: ₹1,80,00,000
Increase: ₹30,00,000
Percentage Increase:
[
\frac{30,00,000}{1,50,00,000} \times 100 = 20%
]
Key Takeaway: Always label units (₹ lakh) and double-check calculations.
3. Diagrammatic Reasoning (DR)
Key Topics:
Sequence Completion
Pattern Recognition
Rotational/Reflective Symmetry
Sample Question 3:
Determine the next diagram in the sequence below, where shapes rotate 90° clockwise each step.
Solution:
Each diagram rotates the central shape clockwise.
Next Diagram: A triangle pointing downward (from D).
Key Takeaway: Observe symmetry and incremental changes.
Final Tips for CAT LRDI Slot 2
Time Management: Allocate 35 mins to DI, 25 mins to LR, and 10 mins to DR.
Practice Prioritization: Solve easy DI questions first (e.g., percentage/average calculations).
Check for Traps:
DI: Look for distractors like "total sales" vs. "sales per region."
LR: Verify constraints (e.g., "not adjacent," "exactly two people").
