Question
207 litres mixture of milk and water is mixed in an
empty container in the ratio 5:4, respectively. If 18 litres of mixture is replaced with 18 litres of water then what will the ratio of milk to water in the resultant mixture? MTSolution
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
