    Question

    If 50% of ‘r’ is equal to 4 times 30% of ‘s’,

    and ‘r’ is 60% of 300, what is the value of ‘s’?
    A 75 Correct Answer Incorrect Answer
    B 50 Correct Answer Incorrect Answer
    C 48 Correct Answer Incorrect Answer
    D 35 Correct Answer Incorrect Answer

    Solution

    ATQ,

    r = 300 × 0.6 = 180

    According to the question,

    180 × 0.5 = 4s × (30/100)

    Or, 90 = 4s × 0.3

    Or, 90 = 1.2s

    Or, s = 90 / 1.2 = 75
