    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.

    D 20 kg Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    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
