Volume after juice - volume before juice = volume of juice
3/5 - 1/4 = 7/20
12/20 - 5/20 = 7/20

Volume in glass / total volume of the glass = Volume of juice
7/20 = 70cm^3
so
20/20 = 200cm^3

Therefore, the volume of the glass is 200cm^3

3/5 = 1/4 + 70
12/20 = 5/20 + 70
7/20 = 70 --> 1/20 = 10 --> 20/20 = 200
Whole glass is 200cm^3
