      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
