    Question

    The ratio of M to N is 4:9, and that of N to O is 3:2. If

    the difference between O and M is 60, what is the total of M, N, and O?
    A 845 Correct Answer Incorrect Answer
    B 570 Correct Answer Incorrect Answer
    C 915 Correct Answer Incorrect Answer
    D 665 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let M = 4x and N = 9x

    Then, O = 9x × (2/3) = 6x

    Now according to the question,

    O – M = 6x – 4x = 2x = 60

    So, x = 60 / 2 = 30

    Then, M + N + O = 4x + 9x + 6x = 19x = 570
