Boys to girls is 4:5.......added = 9

Answer: 42
Step-by-step explanation:
if the bookstore has 64 copies,
yesterday it was sold 1/4 , so it was sold 64/4=16
today it was sold 1/8 from what remained, which is 6(see below)
64-16=48
48/8=6
the store has left 48-6=42

The answer is 960.
8 x 12 x 20 is 1920. 1920 divided by 2 is 960.
