A jar contains a mixture of milk and water in the respective ratio of 3:1. When 4 litre of the mixture is taken out and thereafter 3 litre of milk is added to the remaining mixture. The respective ratio of milk and water in the resultant mixture thus formed is 4:1. What was the initial quantity of water in the mixture
Let the quantity of water in the mixture = x litre
and the quantity of milk in the mixture = 4x litre
According to question,
[3x-4(3/4)+3]÷[x-4(1/4)]=4/1
3x=4x-4
x=4
∴ Initial quantity of water in the mixture = 4 litre
