Answer:
Volume: 1/2V + 65 = 6/7V
(Half glass added by Orange juice is equal to 6/7 of thr glass being full)
Multiply by 14 (To cancel the denominators. 7 can't cancel with 2 so take 14)
7V + 910 = 12V
5V= 910
V= 182
Thus, Volume of glass is 182 cm³

ANSWER...
A glass is 1/2 means = 3.5 / 7
if 65cm^3 is poured means = 6 /7
then 65cm^3 = 2.5/7
volume be x
therefore
(2.5 × X ) / 7 = 65
X =( 65×7) / 2.5
X = 455 / 2.5
total volume of glass = 182 cm^3
