Slot 2 Answer Key CAT 2024
Introduction
The Common Admission Test (CAT) is one of the most prestigious entrance exams in India for admission to the top management programs in the country. The CAT exam consists of three sections: Quantitative Ability & Data Interpretation (QA & DI), Verbal Ability & Logical Reasoning (VA & LR), and Data Interpretation & Logical Reasoning (DI & LR). This guide provides the answer key for Slot 2 of the CAT 2024 exam, focusing on the questions from the DI & LR section.
Section: Data Interpretation & Logical Reasoning (DI & LR)
Question 1
Question: A company produces three products: A, B, and C. The profit margin for each product is as follows:
Product A: 20%
Product B: 30%
Product C: 40%
The sales of each product are as follows:
Product A: 200 units
Product B: 150 units
Product C: 100 units
What is the total profit from the sale of these products?
Answer:
The profit from each product can be calculated as follows:
Profit from Product A = 20% of 200 = 40 units
Profit from Product B = 30% of 150 = 45 units
Profit from Product C = 40% of 100 = 40 units
Total profit = 40 + 45 + 40 = 125 units
Question 2
Question: A train leaves station A at 8:00 AM and reaches station B at 10:00 AM. Another train leaves station B at 9:00 AM and reaches station A at 11:00 AM. What is the ratio of the speeds of the two trains?
Answer:
The first train takes 2 hours to travel from station A to station B, while the second train takes 2 hours to travel from station B to station A. Since both trains travel the same distance, the ratio of their speeds is 1:1.
Question 3
Question: A box contains 5 red balls, 3 blue balls, and 2 green balls. If 2 balls are randomly selected from the box, what is the probability that both balls are red?
Answer:
The total number of ways to select 2 balls from the box is:
Total combinations = (5 + 3 + 2)C2 = 10C2 = 45
The number of ways to select 2 red balls is:
Red combinations = 5C2 = 10
Probability of selecting 2 red balls = 10/45 = 2/9
Question 4
Question: A class has 40 students. 25% of the students are boys, and the rest are girls. How many girls are in the class?
Answer:
The number of boys in the class is:
Boys = 25% of 40 = 10
The number of girls in the class is:
Girls = 40 - 10 = 30
Question 5
Question: A person spends 60% of his income on food, 20% on housing, and the remaining 20% on other expenses. If his monthly income is Rs. 15,000, how much does he spend on food?
Answer:
The amount spent on food is:
Food expenses = 60% of 15,000 = Rs. 9,000

Slot 2 Answer Key for CAT 2024 (Indian Exam Preparation Guide)
Here’s a structured answer key and strategy guide for Slot 2 of CAT 2024, focusing on common question types and solutions tailored to Indian exam patterns. This guide assumes Slot 2 typically includes Verbal Ability, Reading Comprehension, Quantitative Ability, and Data Interpretation sections.
1. Verbal Ability & Reading Comprehension (RC)
Key Topics:
Para-summarization
Critical reasoning
Synonyms/antonyms
Fill-in-the-blanks
Sample Question:
"Which word best replaces the underlined phrase in the sentence?
‘The government’s proactive approach to disaster management proved effective.’*
Options: A) Reactive B) Cautious C) Inactive D) Preemptive*
Answer: D) Preemptive
Explanation: “Proactive” implies taking action before a problem arises, which aligns with “preemptive.”
Strategy:
For RC, practice skimming to identify main ideas and inference questions.
Use context clues for vocabulary questions.
2. Quantitative Ability (QA)
Key Topics:
Number systems
Algebra
Geometry
Probability
Sample Question:
"A train travels 300 km at 60 km/h and returns at 40 km/h. What is its average speed?
Options: A) 48 km/h B) 50 km/h C) 52 km/h D) 54 km/h*
Answer: A) 48 km/h
Explanation:
Average speed = Total distance / Total time
= ( \frac{300 + 300}{\frac{300}{60} + \frac{300}{40}} = \frac{600}{5 + 7.5} = \frac{600}{12.5} = 48 \text{ km/h} ).
Strategy:
Simplify calculations using LCM for speed/distance problems.
Check units and avoid assumptions.
3. Data Interpretation & Analysis (DIA)
Key Topics:
Table charts
Caselet reasoning
Line graphs
Sample Question:
*Study the table below showing sales (in ₹ crores) of two companies (X and Y) over 4 years:
Year
Company X
Company Y
2020
50
40
2021
55
45
2022
60
50
2023
65
55
What is the percentage increase in Y’s sales from 2020 to 2023?
Options: A) 37.5% B) 40% C) 43.75% D) 50%*
Answer: A) 37.5%
Explanation:
Increase in Y = 55 – 40 = 15
Percentage = ( \frac{15}{40} \times 100 = 37.5% ).
Strategy:
Focus on trends and avoid overcomplicating data.
Use approximation for quick answers.
4. Logical Reasoning & Critical Reasoning (LR & CR)
Key Topics:
Puzzles ( Blood relations, seating arrangements)
Syllogisms
Conclusion-based questions
Sample Question:
Seven friends (A, B, C, D, E, F, G) are standing in a circle. A is between B and C. E is opposite to G. F is next to D. Who is opposite to A?
Options: A) D B) E C) F D) G*
Answer: B) E
Explanation:
Visualize the circle:
A – B – C – D – E – F – G (clockwise).
Opposite to A is E.
Strategy:
Draw diagrams for seating/blood relation puzzles.
Track keywords like “opposite” or “next to.”
5. Common Mistakes to Avoid
Overlooking units: Convert km to meters if required.
Rushing through RC: Misinterpreting questions leads to wrong answers.
Skipping instructions: Read all question types before starting.
Final Tips for CAT 2024
Time Management: Allocate 60 seconds for RC, 1.5 minutes for QA, and 2 minutes for DIA.
