In a mixture of 35 litres, the ratio of milk and water is 4:1. If 7 litres of water is added to the mixture, the ratio of milk and water of the new mixture will be

Correct Answer: 2:1

Ratio of milk andwater = 4:1

Quantity of water = 35/5 = 7 litres

Quantity of milk = 35 X 4/5 = 28 litres

If 7 litre of water is added, new quantity of water = 14 litre

New ratio of milk and water = 28:14 = 2:1
