Here is how I got it:
Average is 35 ounces
x is # of 20 ounce bottles
y is # of 40 ounce bottles
20x+40y/x+y = 35
solve to get y=3x
x+y=48 bottles
x=12, y=36
20x+40z/x+z=25
plug x=12 and solve for z, we get z = 4
So, y-z is # of bottles sold i.e 36-4 = 32

No. The question asks about the average weight of bottles which are not sold.

The current average of 20 (35 - 15) and 40-ounce (40 - 5) bottles is 35, thus there must be 3 times as many 40-ounce bottles as 20-ounce bottles. Since there are total of 48 bottles, then there must be 12 20-ounce bottles and 36 40-ounce bottles.
Now, we need to sell ONLY 40-ounce bottles so that the average to become 25. Same way, 25 is 5 away from 20 and 15 away from 40, so after selling some number of 40-ounce bottles, there must be 3 times as many 20-ounce bottles as 40-ounce bottles. So, there must be 12 20-ounce bottles and 12/3 = 4 40-ounce bottles.
Therefore, 36 - 4 = 32 40-ounce bottles must be sold.
Answer: D.
Hope it's clear.
