A vessel contains a mixture of milk and water and the quantity of milk is three times more than that of water. If 25 liters of the mixture is taken out and 15 liters of water is added to the mixture, then the ratio of milk to water becomes 2:1. Find the quantity of the mixture in the vessel initially?<\/p>\n\n\n\n
