A vessel contains 320 litres of milk and water in the ratio of 5:3. 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 = 320 × 5/8 = 200 litres The quantity of water in the initial mixture = 320 - 200 = 120 litres The ratio of milk to water in the final mixture = (200 + 10) : 120 = 210:120 = 7:4
