There are two sections E and F of a class, consisting of 68 and 98 students respectively. If the average weight of section E is 60 kg and that of section F is 55 kg. What is the average weight of the whole class?

Number of total students = 68+98 = 166
Total weight of students = (68x60+98x55)kg = 9470kg
Average weight of the whole class = 9470/166= 57.04kg
