Question
The average weight of 32 employees in an office is 38
kg, while the average weight of 6 managers overseeing these employees is 62 kg. If 12 employees and 2 managers go for a picnic, the average weight of the remaining employees and managers becomes 35 kg and 61 kg, respectively. Calculate the average weight of the people who went for the picnic.Solution
ATQ, 12 employees and 2 managers went for the picnic which means that 20 employees and 4 managers did not go to the picnic. Total weight of 12 employees who went for picnic = 38 × 32 – 35 × 20 = 1216 – 700 = 516 kg Total weight of 2 managers who went for picnic = 62 × 6 – 61 × 4 = 128 kg Total weight of all the people who went for the picnic = 516 + 128 = 644 kg Required average = 644/14 = 46 kg
