A vessel contains 210 litres of milk and water in the ratio of 5:2. If 10 litres of milk is added to the mixture, then find the ratio of milk to water in the final mixture.
The quantity of milk in the initial mixture = 210 × 5/7 = 150 litres The quantity of water in the initial mixture = 210 - 150 = 60 litres The ratio of milk to water in the final mixture = (150 + 10) : 60 = 160:60 = 8:3
