There were 3 glasses containing the same volume of liquid. Mr Lee poured 210 ml of the liquid from Glass A into Glass C, and 150 ml of the liquid from Glass B into Glass C. In the end, the ratio of the volume of liquid in Glass A to the volume of liquid in Glass B was 3:8.
A.) What was the final volume of liquid in Glass A?
B.) What was the volume of liquid in each glass at first?

(x210)/(x150) = 3/8
8x1680 = 3x  450
5x = 1230
x = 246
all glasses had 246 ml at first
246210 = 36 ml left in A
246150 = 96 ml left in B
36/96 = 3:8
