In a mixture of 60 litres, the ratio of milk and water is 5:3. In order to make this ratio 1:2, the quantity of water to be added to the mixture is

17.5 litres
22.5 litres
58.5 litres
52.5 litres

Correct answer: 52.5 litres

Solution

In 60 litres with ratio 5:3, milk = 37.5 litres and water = 22.5 litres. To make the ratio 1:2, water must become 75 litres, so water to be added = 75 - 22.5 = 52.5 litres.
