    Question

    Suppose, ‘m’ is directly proportional to ‘n’, and

    when m = 96, n = 24. What will be the value of ‘m’, when ‘n’ becomes 60?
    A 265 Correct Answer Incorrect Answer
    B 240 Correct Answer Incorrect Answer
    C 280 Correct Answer Incorrect Answer
    D 272 Correct Answer Incorrect Answer

    Solution

    ATQ,

    m ∝ n

    So, Let, m = k × n (where, ‘k’ is a proportionality constant)

    ATQ,

    96 = k × 24

    So, k = (96 / 24) = 4

    So, when ‘n’ = 60, then,

    m = 4 × 60 = 240
