      Question

      The efficiency of P, Q, R, S are in the ratio of

      6:5:4:3. If P and R can do a work together in 6 days. Then How many days Q and S will take to complete the same work?
      A 15/2 days Correct Answer Incorrect Answer
      B 17/2 days Correct Answer Incorrect Answer
      C 19/2 days Correct Answer Incorrect Answer
      D none of these Correct Answer Incorrect Answer

      Solution

      Efficiency of (P+R) = (6+4) = 10 Days taken by (P + R) together to complete the work = 6 days Efficiency of (Q + S) = (5+3) = 8 So, Q and S will take time = (Total days of (P + R) × Total Efficiency of (P + R)) / (Total Efficiency of (Q + S)) = (6 ×10)/8 = 60/8 = 7(1/2) days
