    B 35:34 Correct Answer Incorrect Answer
    C 25:21 Correct Answer Incorrect Answer
    D 11:13 Correct Answer Incorrect Answer
    E 14:19 Correct Answer Incorrect Answer

    Solution

    Initially, amount of milk = (5/9) × 207 = 115 litres Amount of water = (4/9) × 207 = 92 litres 18 litres of mixture is replaced. Amount of milk replaced = 18 x (5/9) = 10 Amount of water replaced = 18 x (4/9) = 8 So, required ratio = (115 – 10):(92 – 8 + 18) = 105:102 = 35:34
