1. Winnie-the-Pooh decided to give Eeyore a pot of honey. On the way to Eeyore, he tried the honey from the pot several times. When he tried the honey for the first time, the pot became half as heavy. And after the second time, the pot became half as heavy again. And after the third! And after the fourth! Indeed, after the fourth time, there was no honey left. How much honey did Winnie-the-Pooh eat if the pot without honey weighs 200 grams?
Solution. $\quad$ Answer: 3000 g. Indeed, $3000=(((200 \cdot 2) \cdot 2) \cdot 2) \cdot 2)-200$.
