Everyone is 9 fast * 3 people = 27 fast-waiter 2 fast = boss 25 fast.

This question is confusing ... first of all, it misleads everyone.

We can also do reverse calculation. Let's start from the back. According to the boss, it costs 2 for three people to stay one night.

5 yuan ~, because 25 is not divisible by 3, we just ignore 1 yuan for the time being.

So 25- 1 = 24 yuan. 24/3 = 8 yuan, so everyone gets 8 yuan on average.

But after the waiter came, he returned 3 yuan, with an average of/kloc-0 yuan per person, because I just did the reverse calculation.

So three people each get one yuan more, so 8+ 1 = 9 yuan, 3 * 9 = 27 yuan.

27 yuan and greedy waiter 2 yuan make 27+2 = 29 yuan.

Why 29 yuan again? Don't worry, I just ignored 1 yuan, remember?

29+ 1 = 30 yuan, so the dollar is there.
