      Question

      β€˜A’ can do a piece of work in 15 days. β€˜B’ can

      do 80% of the same work in 20 days. If they work together for the entire time and get paid Rs.1408, then find the share of β€˜A’.
      A Rs.800 Correct Answer Incorrect Answer
      B Rs.880 Correct Answer Incorrect Answer
      C Rs.900 Correct Answer Incorrect Answer
      D Rs.760 Correct Answer Incorrect Answer

      Solution

      Let the total work be 60 units. (LCM of 15 and 20) Efficiency of A = 60/15 = 4 units/day Efficiency of B = (60/20) Γ— (80/100) = 12/5 units/day Ratio of the efficiency of A : B = 4 : 12/5 = 5:3 Share of A = (5/8) Γ— 1408 = Rs.880
