    • 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
