    Question

    The total of two numbers ‘u’ and ‘v’ is 600. If

    ‘u’ is reduced by 12% and ‘v’ is increased by 18%, both become equal. Find the value of ‘v’.
    A 339.62 Correct Answer Incorrect Answer
    B 286.25 Correct Answer Incorrect Answer
    C 167.44 Correct Answer Incorrect Answer
    D 256.70 Correct Answer Incorrect Answer

    Solution

    ATQ,

    u + v = 600 ……(i)

    ATQ,

    0.88 × u = 1.18 × v

    Or, u = (1.18 / 0.88) × v

    So, u = (59v / 44)

    Put the value of ‘u’ in equation (i), we get,

    (59v/44) + v = 600

    Or, (103v/44) = 600

    Or, v = 600 × (44/103)

    So, v = 256.70
