In a 10-kilogram solution of water and oil, the ratio by mass of water to oil is 3 : 2. If 8 kilograms of a solution consisting of 2 parts of water to 1 part of oil are added to the 10-kilogram solution, what fraction by mass of the new solution is oil?

10 kg solution ----> w/o = 3/2 or 6kg/4kg.
8 kg solution -----> w/o = 2/1 or 16/3 kg / 8/3 kg
Weight of oil in new solution = 4 + 8/3 --> 20/3 kg
What fraction by mass of the new solution is oil ---> 20/3 / 18 ----> 10/27
8 kg solution -----> w/o = 2/1 or 16/3 kg / 8/3 kg
Weight of oil in new solution = 4 + 8/3 --> 20/3 kg
What fraction by mass of the new solution is oil ---> 20/3 / 18 ----> 10/27
