      Question

      The efficiency of A,B,C,D are in the ratio of 6:5:4:3.

      If A and C can do a work together in 6 days. Then How many days B and D will take to complete the same work?
      A 7.5 days Correct Answer Incorrect Answer
      B 8.3 days Correct Answer Incorrect Answer
      C 10 days Correct Answer Incorrect Answer
      D 8 days Correct Answer Incorrect Answer

      Solution

      Let A can do 6 units per day then C can do 4 units per day So days taken by (A+C) together to complete the work = 6 days So total work = (6+4)*6 = 60 units Efficiency of (B+D) = (5+3) = 8 So B & D will do this job in = 60/8 = 7.5 days
