2. One bottle 1.

I drank two-fifths of the wine for the first time.

There are 2/5 sprite and 3/5 wine when loading sprite.

I also drank 1 for three, so two elves drank 15 and five drank 1.

So I drank 65438+2/5 Sprite and 3/5 wine.

Fill it with sprite, so there are 3/5 sprite and 2/5 wine.

Drink 15% 1 1 Sprite and 1 wine after drinking.

So there is more wine, more than 65438+4/05.

3.8 5+ 12 7=24 29.

29 out of 24-1= 5 out of 24
