A monkey picked 100 bananas in the banana forest. The monkey is going to take them all home. The monkey's home is 50 meters away, and the monkey can carry up to 50 bananas home at a time. But monkeys are greedy and eat a banana every meter. How many bananas can this monkey take home at most?

(Note: Monkeys can take home up to 50 bananas at a time, which is limited to 50 bananas, so they must take them twice. If they go home without bananas, it will be a tragedy. Besides, monkeys won't eat bananas. O(∩_∩)O Haha ~ Is that right?

Answer: First, carry 50 bananas. By the time we reached 25 meters, we had eaten 25 bananas and there were 25 left. Then we put this pile down and go back. Then carry the remaining 50 on your back. By the time you reach 25 meters, you have already eaten 25 bananas, and there are 25 left. Back 25 just put it down, * * * 50; After walking 25 meters, I ate 25 more at home, so there are 25 left at home.
