Consider the following: 6 boys' weight = 7 girls' weight = 3 men's weight = 4 women's weight. If the average weight of women is 63 kg, what is the average weight of boys?
A.40 kg
B.42 kg✓ Correct
C.45 kg
D.63 kg
Explanation
Total weight of 4 women = 4 × 63 = 252 kg. This equals total weight of 3 men, 7 girls, and 6 boys. So total weight of 6 boys = 252 kg, and average weight per boy = 252/6 = 42 kg.
