Correct Answer

Explanation

The average weight of all the students in the class is 48.55 kg.
To find this, we can use the following steps:
The average weight of 16 students in the class is 50.25 kg.
The average weight of the remaining 8 students is 45.15 kg.
The total weight of all the students in the class is 16 * 50.25 + 8 * 45.15 = 1165.20 kg.
The total number of students in the class is 24.
Therefore, the average weight of all the students in the class is 1165.20 / 24 = 48.55 kg.
