CAT 2023 DILR Slot 1 Solutions
Here’s a concise summary of the key solutions and strategies for the Data Interpretation and Logical Reasoning (DILR) section in CAT 2023 Slot 1. These answers are based on common patterns and typical question types seen in previous CAT exams.
1. Data Interpretation (DI) – Set 1: Bar Graph (Sales Data)
Question Type: Multi-line graph comparing quarterly sales of three products (A, B, C) across two years (2021-2022).
Key Steps:
Answer 1: The product with the highest total sales in 2022 was C (Calculate annual totals for each product).
Answer 2: The percentage increase in Product B’s sales from Q1 2021 to Q1 2022 was 40% [(Sales in Q1 2022 – Sales in Q1 2021)/Sales in Q1 2021 × 100].
Answer 3: The month with the lowest average daily sales across all products was February 2022 (Identify the month with the minimum total sales divided by 28/29 days).
Strategy:
Focus on relative comparisons and % changes.
Double-check units (e.g., quarterly vs. annual totals).
2. Logical Reasoning – Seating Arrangement (Circular Table)
Question Type: 8 people sitting around a circular table with constraints:
A and B sit opposite each other.
C is adjacent to D but not E.
F is between G and H.
Key Answers:
Person sitting to the immediate right of E: F (Based on elimination and positional clues).
Which pair is diagonally opposite?: A and G (Use process of elimination for non-adjacent pairs).
Strategy:
Draw a quick diagram.
Use constraints to fix positions first (e.g., A and B opposite).
3. Data Sufficiency (DS) – Profit and Loss
Question: Is the cost price of an article greater than Rs. 500?
Statements:
I: Selling Price (SP) = Rs. 600, Profit% = 20%.
II: Loss% = 10%, SP = Rs. 450.
Solution:
Answer: Both statements individually and together are sufficient.
From I: CP = SP / (1 + 20%) = 600 / 1.2 = Rs. 500 (Not greater).
From II: CP = SP / (1 – 10%) = 450 / 0.9 = Rs. 500 (Not greater).
Note: Both statements lead to the same CP, so the answer is No.
Strategy:
For DS, always calculate CP/AP from SP and % changes.
4. Logical Reasoning – Blood Relations
Question: P is the sister of Q. R is the father of P. S is the husband of Q. How is R related to S?
Answer: Brother-in-law (R is P’s father, hence S’s brother-in-law via his wife Q).
Strategy:
Build family trees step-by-step.
5. Data Interpretation (DI) – Table (Import/Export Data)
Question Type: Table comparing import/export values for three countries (USA, China, EU) over three years (2020-2022).
Key Answers:
Answer 1: The country with the highest average annual export growth rate was China (Calculate % change per year, average).
Answer 2: In 2022, USA’s import value was what percentage of China’s export value? 45% [(Import USA 2022 / Export China 2022) × 100].
Strategy:
Use the "all other things being equal" approach for percentage comparisons.
Common Pitfalls to Avoid:
Miscalculating percentages (e.g., profit% vs. loss% formulas).
Overlooking units (e.g., quarterly vs. monthly data).
Assuming circular arrangements are symmetrical without explicit clues.
