      Question

      A can complete a work in 10 days. B takes 4 days less

      than A to complete the same work. In how many days can both of them together complete 80% of the work together?
      A 8 days Correct Answer Incorrect Answer
      B 3 days Correct Answer Incorrect Answer
      C 10 days Correct Answer Incorrect Answer
      D 4.5 days Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Time taken by B to complete the work = 10 โ€“ 4 = 6 days Let the total work = 30 units Efficiency of A = 30/10 = 3 units/day Efficiency of B = 30/6 = 5 units/day Required time taken = 0.80 x 30/(3+5) = 3 days
