The price of two litres of milk is equal to the price of 12 litres of water. Find the ratio of price of water to milk in a mixture of 3 litres of water and 11 litres of milk.

Correct Answer: 22 : 1
Let the price of 1 litre of milk be x. The price of 2 litres of milk = 2 * x = 2x The price of 1 litre of water = 2x / 12 = x / 6 The price of milk in the mixture = x * 11 = 11x The price of water in the mixture = x * 3 / 6 = x / 2 = 0.5x The ratio of price of water to milk in the mixture = 0.5x : 11x = 1 : 22
