    Question

    There are four fractions M, N, O, and P such that when M

    is divided by N, the result is 3/5 and when N is divided by O, the result is 3/2, and when O is divided by P, the result is 8. If M exceeds P by 31/45, then what is value of fraction N?
    A 5/6 Correct Answer Incorrect Answer
    B 3/2 Correct Answer Incorrect Answer
    C 4/3 Correct Answer Incorrect Answer
    D 4/5 Correct Answer Incorrect Answer

    Solution

    M/N = 3/5 = 9/15 = 36/60
    N/O = 3/2 = 15/10 = 60/40
    O/P = 8 = 40/5
    So, M: N: O: P = 36: 60: 40: 5
    Let M = 36k, N = 60k, O = 40k, and P = 5k
    => M - P = 31/45
    => 36k - 5k = 31/45
    => 31k = 31/45
    => k = 1/45
    Hence, N = 60k = 60/45 = 4/3
