A math problem that has stumped countless people around the world—can you solve it?
Three people went to stay overnight, costing 30 yuan per night. The three each paid 10 yuan to make up the 30 yuan and handed it to the owner. Later, the owner said that there was a discount today so only 25 yuan was needed, took out 5 yuan, and told the waiter to return it to them. The waiter secretly kept 2 yuan, and then gave the remaining 3 yuan to the three people, 1 yuan each. So, each initially paid 10 yuan, and now got back 1 yuan, which means 10 - 1 = 9, so each person only spent 9 yuan. The three people spent 9 yuan each, 3 x 9 = 27 yuan + the 2 yuan the waiter kept = 29 yuan. Where did the remaining 1 yuan go???

The boss collected 30 - 5 = 25 yuan, they spent 25 + 3 = 28 yuan, the waiter collected 2 yuan, 28 + 2 = 30 yuan, just 30 yuan.
