##### Question from UPSC Prelims 2024 CSAT Paper

**Explanation:**

## Average weight of the boys?

Let’s approach this step-by-step:

1) First, let’s establish the relationships:

6 boys = 7 girls = 3 men = 4 women

2) We’re given that the average weight of women is 63 kg. Let’s find the total weight of 4 women:

4 women = 4 × 63 kg = 252 kg

3) Now we know that 252 kg is equal to the weight of 6 boys. Let’s set up an equation:

6x = 252, where x is the average weight of one boy

4) Solving for x:

x = 252 ÷ 6 = 42 kg

5) Therefore, the average weight of the boys is 42 kg.

The correct answer is b) 42 kg.
