      Question

      A vessel contains 280 litres of milk and water in the

      ratio of 9:5. If 20 litres of milk is added to the mixture, then find the ratio of milk to water in the final mixture.
      A 2:1 Correct Answer Incorrect Answer
      B 11:8 Correct Answer Incorrect Answer
      C 3:2 Correct Answer Incorrect Answer
      D 7:4 Correct Answer Incorrect Answer
      E 8:3 Correct Answer Incorrect Answer

      Solution

      The quantity of milk in the initial mixture = 280 Γ— 9/14 = 180 litres The quantity of water in the initial mixture = 280 - 180 = 100 litres The ratio of milk to water in the final mixture = (180 + 20) : 100 = 200:100 = 2:1
