Calculation of Average Weight of all Students
- First, calculate the total weight of 6 students:
6 students * 50 kg/student = 300 kg
- Then, calculate the total weight of 2 students with an average weight of 57 kg:
2 students * 57 kg/student = 114 kg
- Next, calculate the total weight of 2 students with an average weight of 55 kg:
2 students * 55 kg/student = 110 kg
- Now, add the total weight of all students together:
300 kg + 114 kg + 110 kg = 524 kg
- Finally, to find the average weight of all students, divide the total weight by the total number of students:
524 kg / 10 students = 52.4 kg
Therefore, the average weight of all students is 52.4 kg, which corresponds to option 'C'.
