<PRE><B>Question 352090</B>
1000 Litre milk contains some percent milk and some percent water. Now add some 70 Litre water to the above mixture. What is the percentage of water in the mixture?
---
Assume the 1000 litres is x% milk.
Then it is (100-x)% water
Total water is [(100-x)/100]*1000 = 10(100-x) = 1000-10x litres
--------------------------------
Total liquid after adding 70 litres of water is 1070 litres.
-----
% of water in the final amount = (1000-10x)/1070 = (100-x)/107
===========================
