    A 40.2 Correct Answer Incorrect Answer
    B 52.5 Correct Answer Incorrect Answer
    C 62.2 Correct Answer Incorrect Answer
    D 78.5 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let us assume one of the numbers is 'x'

    Then, another number is = 4 ├Ч x = '4x'

    So, x ├Ч 4x = 720

    Or, 4x┬▓ = 720

    Or, x┬▓ = 180

    Or, x = 13.4 {Since the numbers are positive}

    Required difference = {4 ├Ч (13.4) - 13.4} = (53.6 - 13.4) = 40.2
