Q36. 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?
Detailed Solution
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.
