A bottle of wine, 2 yuan, two bottles, four wine lids and a bottle of ten yuan. How many bottles can I drink?
10 yuan buys 5 bottles of wine and gets 5 bottles and 5 lids.

Borrow a wine bottle, you can get 3+ 1 bottle of wine, and there are 1 lids left.

So I got three bottles with four lids, and I got 1+ 1 bottle of wine.

So the two bottles were changed to 1 bottle, and the bottle was returned.

So * * * gets 5+3+1+1+1=1(bottle).
