    The average weight of 25 employees in an office

    increases by 0.8 kg when the weight of the manager is included. If earlier the average weight of the employees was 68 kg, then find the weight of the manager.
    A 75.9 kg Correct Answer Incorrect Answer
    B 79.7 kg Correct Answer Incorrect Answer
    C 84.5 kg Correct Answer Incorrect Answer
    D 88.8 kg Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Total weight of the employees (Excluding the weight of the manager) = 25 × 68 = 1700 kg New total weight of the employees = 26 × (68 + 0.8) = 26 × 68.8 = 1788.8 kg So, weight of the manager = 1788.8 - 1700 = 88.8 kg
