Three people went to stay for 30 yuan a night. Each of the three people took out 10 yuan to collect 30 yuan and gave it to the boss.
Later the boss said that today's discount was only 25 yuan, so he took out 5 yuan and ordered the waiter to return it to them
The waiter secretly hid 2 yuan and then distributed the remaining 3 yuan to the three people, each of whom received 1 yuan
In this way, each person paid out at first I paid 10 yuan, and now I get 1 yuan back, which is 10 minus 1 = 9. Each person only spent 9 yuan. Three people paid 9 yuan each. 3 times 9 = 27 yuan. The 2 yuan hidden by the waiter is equal to 29 yuan. Where did the other 1 yuan go?
(grade=5) Correct answer: The waiter took 2 yuan out of 27 yuan, so 27 minus 2 equals 25, 25 plus the waiter's 2 yuan, plus 1 yuan distributed to three people, that is, 25+2+3=30, is the answer correct? (/grade)

This is considered wrong! Together they only paid 3×9=27. The 27 already includes the 2 yuan for the waiter plus the 25 yuan taken by the boss, so when you add the 3 yuan in their own hands, there is nothing wrong!
