40 kg

42 kg

45 kg

63 kg

- Each group has the same total weight: 6 boys = 7 girls = 3 men = 4 women.

- Therefore, their total weight can be equated:

- Total weight of 4 women = 4 × 63 = 252 kg.

- This means the total weight for each group (6 boys, 7 girls, 3 men) is also 252 kg.

- To find the average weight of the boys:

- Total weight of 6 boys = 252 kg.

- Average weight of boys = Total weight of boys / Number of boys = 252 / 6 = 42 kg.

- 42 kg is the correct average weight of the boys (Option:2).
