    Question

    If 20% of ‘m’ equals 3 times 50% of ‘n’, and

    ‘m’ is 85% of 600, what is the value of ‘n’?
    A 68 Correct Answer Incorrect Answer
    B 50 Correct Answer Incorrect Answer
    C 48 Correct Answer Incorrect Answer
    D 35 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    m = 600 × 0.85 = 510

    According to the question,

    510 × 1/5 = 3n × (50/100)

    Or, 102 = 3n × 0.5

    Or, 102 = 1.5n

    Or, n = 102 / 1.5 = 68
