      Question

      Alok and Vinay can complete some work alone in 12 days

      and 20 days respectively. Both of them started the work together but Vinay left the work 4 days before the completion. For how many days both of them have worked together?
      A 5 Correct Answer Incorrect Answer
      B 4 Correct Answer Incorrect Answer
      C 8 Correct Answer Incorrect Answer
      D 6 Correct Answer Incorrect Answer

      Solution

      Let the total work be 60 units (LCM of 12 and 20) . Efficiency of Alok = (60/12) = 5 units/day Efficiency of Vinay = (60/20) = 3 units/day If Alok and Vishal worked together for 'N' days, then; (5 + 3) X N + (5 X 4) = 60 Or, 8N = 60 - 20 So, 'N' = (40/8) = 5
