In a mixture of 60 litres, the ratio of milk to water is 2:1. If this ratio is to be 1:2,then find the quantity of water to be further added.

60 litres 2:1 means 1 out of (2+1) , or 1/3 is water = 20 liters and 40 litres is milk

40 litres of milk will be 1/3 of the new mixture 2/3 will be water = 80 litres

so you will have to add 60 litrers of water to the original 20 liters

The ratio of 2: 1 for a mixture of 60 liters means:

2/3 x 60 = 40 liters of milk

1/3 x 60 = 20 liters of water

So, to get the ratio down to 1 : 2, you have to add L liters of water:

M /[W + L] = 1 / 2

40 / [20 + L] = 1 / 2

80 =20 + L

L = 60 Liters of water have to be added to 60 Liters of mixture so that you have:

20 Liters of water + 60 Liters =80 Liters of water to 40 Liters of milk, or a ratio of 1 : 2.
