In 60 litres mixture of milk and water, the ratio of volumes of milk and water is 3 : 2. If we want the ratio of the volumes of milk and water to be 1 : 1, then how much water should be added to the mixture?

In 60 litres mixture of milk and water the ratio of volumes of milk and water is 3x : 2x

5x = 60

x = $$\frac{60}{5} $$

x = 12

therefore milk = $$ 3 \times 12 = 36 $$

               water = $$ 2 \times 12 = 24 $$

If we want the ratio of the volumes of milk and water to be 1 : 1, then we have to add 12 litres of water.

that is, 12 +24 = 36

volumes of milk and water = 36 : 36

                                        = 1 : 1
