A vessel contains 400 ltmilk. 20 ltof milk was replaced by water and then 40 ltof the resu lt ant mixture was replaced by water. Find the ratio of milk and water in result ant mixture.

A pot contains 81 litres of pure milk.(1)/(3) of the milk is replaced by the same amount of water again (1)/(3), of the mixture is replaced by that amount of water.Find the ratio of milk and water in the new mixture.

20 litres of a mixture contains milk and water in the ratio 5:3 . If 4 litres of this mixture be replaced by 4 litres of milk , the ratio of milk to water in the new mixture would be :

There is pure milk in a vessel . 20% of milk is replaced with water If this process is repeated 3 times , what is the percentage of milk at the end?

20 litres of a mixture contains milk and water in the ratio of 5:3. If four litres of this mixture is replaced by four litres of milk,then the ratio of the milk to that of the water in the new mixture will be 2:3 b.4:3 c.5:3 d.7:3

A vessel contains 20 liters of a mixture of milk and water in the ratio 3:2. 10 liters of the mixture are removed and replaced with an equal quantity of pure milk. If the process is repeated once more, find the ratio of milk and water in the final mixture obtained ?
