    A 185/500 Correct Answer Incorrect Answer
    B 181/500 Correct Answer Incorrect Answer
    C 121/140 Correct Answer Incorrect Answer
    D 121/137 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the required number be 'x'

    (13/20) - x = (7/25)

    Or, x = (13/20) - (7/25)

    Or, x = {(325 - 140)/500}

    So, x = (185/500)
