Answer 2

Step-by-step explanation:

Initially it was 3/4 or 75%=(300/4)%

Net number of bottles of milk =-5+3=-2(negative sign indicates that bottles of milk poured out)

Finally it was =2/3=(200/3)%

Now

(300/4-200/3)%=2

(900-800/12)%=2

(100/12)%=2

25/3%=2

(3×25/3)%=2×3

25%=6

100%= 24(bottle)
