Explanation :
To determine the average weight of the boys, let’s break down the given information:
1. Equality of Weights:
– Weight of 6 boys = Weight of 7 girls = Weight of 3 men = Weight of 4 women = W
2. Average Weight of Women:
– Average weight of one woman = 63 kg
– Total weight of 4 women = 4 × 63 = 252 kg
– Therefore, W = 252 kg
3. Calculating Average Weight of Boys:
– Total weight of 6 boys = W = 252 kg
– Average weight of one boy = 252/6 = 42 kg
Answer: b) 42 kg
