36. Consider the following : Weight of 6 boys = Weight of 7 girls = Weight of 3 men = Weight of 4 women If the average weight of the women is 63 kg, then what is the average weight of the boys?
- A. 40 kg
- B. 42 kg
- C. 45 kg
- D. 63 kg
Answer: B
Explanation
Given that the average weight of the women is 63 kg. Since there are 4 women, their total weight = 4 × 63 kg = 252 kg. The problem states that ‘Weight of 6 boys = Weight of 4 women’. Therefore, the total weight of 6 boys is also 252 kg. To find the average weight of the boys, we divide their total weight by the number of boys: Average weight of boys = 252 kg / 6 = 42 kg. The information about the weights of girls and men is extraneous for solving this specific part of the problem. This question tests basic understanding of averages and direct proportionality.
