      Question

      'B' is 37.5% more productive than 'A'. Together, they

      can finish a task in 40 days. How many days would it take for 'A' alone to complete the entire task?
      A 95 days Correct Answer Incorrect Answer
      B 80 days Correct Answer Incorrect Answer
      C 120 days Correct Answer Incorrect Answer
      D 69(10/11) days Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Let efficiency of β€˜A’ be β€˜8x’ units per day Efficiency of β€˜B’ = 1.375 Γ— 8x = 11x units per day Total work = (11x + 8x) Γ— 40 = (19x Γ— 40) units Desired time = (19x Γ— 40)/8x = 95 days
