Question

    The average age of (x + 2) members in a committee is 22

    years. When a 44-year-old chairman joins, the average age rises to 23 years. Find x% of 500.
    A 95 Correct Answer Incorrect Answer
    B 90 Correct Answer Incorrect Answer
    C 85 Correct Answer Incorrect Answer
    D 80 Correct Answer Incorrect Answer

    Solution

    Total age = 22(x + 2)
    According to question,
    [22(x + 2) + 44] = 23(x + 2 + 1)
    22x + 44 + 44 = 23x + 69
    23x - 22x = 88 - 69
    x = 19
    So, 19% of 500 = 95
