In a mixture of 60 litres, the ratio of milk to water is 2:1. If this ratio is to be 1:2, then the quantity of water to be further added is?
60
Let x be the quantity of water in the mixture.
So 3x=60 x=20 and milk quantity =40
To make the milk : water ratio 1:2, we need to add 60 litres of water so that the water becomes 80 litres as the milk is already 20 litres.
