First, exchange two empty beer bottles for one beer, then 25 bottles of wine, and then use these 25 empty bottles for 12 bottles, leaving 1 empty bottles, so there are 13 bottles, and the remaining 1 bottles can be exchanged for 6 bottles, and the remaining 3 bottles can be exchanged. Finally, I changed two bottles, so I changed 25 bottles. Secondly, you can exchange three lids for 48+50=98 bottles for one bottle of wine. Here, you can exchange the remaining two bottle caps for 32 bottles, and the remaining two =34 bottles can be exchanged for 1 1 bottle with the remaining one, and so on, and then four bottles can be exchanged for 1 bottle, so that the bottle caps are exchanged for 32+65438+. Hope to help you, hope to adopt!
