      work in 12 days. (x + 2) men working 3 hours a day can complete the remaining work in 32 days. Find the value of x.
      A 16 Correct Answer Incorrect Answer
      B 5 Correct Answer Incorrect Answer
      C 3 Correct Answer Incorrect Answer
      D 18 Correct Answer Incorrect Answer

      Solution

      According to the question,
      {(x + 8) × 9 × 12}/0.60 = {(x + 2) × 3 × 32}/0.40
      Or, 3x + 24 = 4x + 8
      Or, x = 16
      Hence, value of x is 16.
