Mixture and Alligation

A container contains milk and water in the ratio 5:3. after boiling the mixture 1.2 liters of water evaporated and the concentration of milk became 75%. find the original volume of the milk in the container if no amount of milk evaporated.   

Q1. a milkman had 60 litres  pure milk. he sold 6 litres pure milk to anand and mixed 6 litres water. he then sold 6 litres of the mixture to bhima and mixed 6 litres water. again he sold 6 litres mixture to sima and added more 6 litres water. now he sold 6 litre of the mixture to rita and mixed  the same amount of water. 

find the difference between quantity of pure milk received by sima and that by rita. 

Q2. If milk man sold the  mixed milk at the rate of the cost price, then find the profit percentage earned from sima.
