A vessel contains 270 litres of milk and water in the
ratio of 5:4. If 15 litres of milk is added to the mixture, then find the ratio of milk to water in the final mixture.Solution
The quantity of milk in the initial mixture = 270 × 5/9 = 150 litres The quantity of water in the initial mixture = 270 - 150 = 120 litres The ratio of milk to water in the final mixture = (150 + 15) : 120 = 165:120 = 11:8
