    Question

    The average of x numbers is 24. If 60% of these

    numbers are reduced by 5 and the remaining 40% are increased by 10, what will be the new average of the x numbers?
    A 25 Correct Answer Incorrect Answer
    B 28 Correct Answer Incorrect Answer
    C 22 Correct Answer Incorrect Answer
    D 21 Correct Answer Incorrect Answer

    Solution

    Sum of ‘x’ numbers = 24x
    New sum of the ‘x’ numbers = 24x – 0.6x × 5 + 0.4x × 10 = 25x
    Therefore, new average = 25x/x = 25
