    Question

    In a team, there are 15 men and 25 women. The average

    weight of each man is 70 kg while that of each woman is 60 kg. What is the average weight of a person in the team?
    A 45.50 kg Correct Answer Incorrect Answer
    B 63.75 kg Correct Answer Incorrect Answer
    C 50.50 kg Correct Answer Incorrect Answer
    D 42.75 kg Correct Answer Incorrect Answer

    Solution

    ATQ,

    Total weight of all the men in the team = 15 × 70 = 1050 kg

    Total weight of all the women in the team = 25 × 60 = 1500 kg

    So, total weight of all the persons in the team = 1050 + 1500 = 2550 kg

    Total number of persons in the team = 15 + 25 = 40

    So, average weight of each person in the team = (2550 / 40) = 63.75 kg
