Detailed Solution
Download Solution PDFGiven:
Average weight of 25 students of section A = 60 kg
Average weight of 35 students of section B = 62.5 kg
Concept used:
Average weight = Total Weight/Total number of students.
Solution:
Total students = 25 + 35 = 60
Total weight of students in Section A = 60 x 25 = 1500 kg
Total weight of students in Section B = 62.5 x 35 = 2187.5 kg
Total weight of 60 students = 1500 + 2187.5 = 3687.5 kg
Average weight = 3687.5/60 = 61.46 kg
Hence, the correct option is 4.
