      Question

      (x + 6) workers complete 40% of a job in 8 days by

      working 5 hours/day. The remaining work is done by (x + 2) workers in 16 days working 5 hours/day. Find x.
      A 16 Correct Answer Incorrect Answer
      B 5 Correct Answer Incorrect Answer
      C 3 Correct Answer Incorrect Answer
      D 10 Correct Answer Incorrect Answer

      Solution

      According to the question,
      {(x + 6) Γ— 8 Γ— 5}/0.40 = {(x + 2) Γ— 16 Γ— 5}/0.60
      Or, 3x + 18 = 4x + 8
      Or, x = 10
      Hence, value of x is 10.
