    Question

    The mean weight of 20 athletes is 70.2 kg. If weights of

    two athletes are excluded, the mean of the remaining becomes 69.5 kg. Calculate the average weight of the two excluded athletes.
    A 76.5 kg Correct Answer Incorrect Answer
    B 53.5 kg Correct Answer Incorrect Answer
    C 72.3 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 20 athletes = 20 × 70.2 = 1404 kg

    Total weight after excluding 2 athletes = 18 × 69.5 = 1251 kg

    Sum of weights of the 2 athletes = 1404 - 1251 = 153 kg

    Average weight of the 2 athletes = 153 ÷ 2 = 76.5 kg
