C Correct answer
Explanation

Total weight = (16 * 50.25) + (8 * 45.15) = 804 + 361.2 = 1165.2. Total boys = 24. Average = 1165.2 / 24 = 48.55.

AI explanation

The total weight of the first 16 boys is 16 multiplied by 50.25, which equals 804 kilograms. The total weight of the remaining 8 boys is 8 multiplied by 45.15, which equals 361.2 kilograms. The average weight of all 24 boys in the class is the total weight of 1165.2 kilograms divided by 24 boys, resulting in 48.55 kilograms.
