Question
264 litres mixture of milk and water is mixed in an
empty container in the ratio 6:5, respectively. If 33 litres of mixture is replaced with 33 litres of water then what will the ratio of milk to water in the resultant mixture? STSolution
Initially, amount of milk = (6/11) × 264 = 144 litres Amount of water = (5/11) × 264 = 120 litres 33 litres of mixture is replaced. Amount of milk replaced = 33 x (6/11) = 18 Amount of water replaced = 33 x (5/11) = 15 So, required ratio = (144 – 18):(144 – 15 + 33) = 126:138 = 21:23
