An irritating little puzzle
I've been stumped by a puzzle which is irritatingly simple (not too difficult  I'm lousy at puzzles).
It is (of course!) an ancient Chinese one. Three men turn up at a hotel and book one room for the night. They are charged 30 yuan. After they have gone upstairs the receptionist realises that he should only have charged them 25 yuan, so he sends up a boy with 5 yuan. The boy can't work out how to divide the money, so he just gives them one yuan each and keeps the two spare yuan for himself.
So the men actually paid 9 yuan each (10 minus the one returned), or 27 yuan in total, and the boy kept 2, giving a total of 29 yuan, not 30. What happened to the extra yuan?

It's funny I was thinking about this very puzzle the other day. Although I had no idea that it was an ancient Chinese affair.Tony.Williams wrote:I've been stumped by a puzzle which is irritatingly simple (not too difficult  I'm lousy at puzzles).

The calculation is a nonsense. If you want to total the 30 Yuan you need to add the 27 they paid to the 3 they were repaid.
The 2 in the boy's pocket, (along with the 25 the hotel charged) is part of the 27 Yuan so adding that to the 27 it's already a part of doesn't make sense

Seen it many times and been told how it works many times and I still need it explained anew each time and each time it's obviously obvious.
I'll memorise Matt's explanation.

Helps to look at it pictorally
Each man ten coins each  makes 30 in total
oooooooooo oooooooooo oooooooooo
Then the hotel has 30 coins
oooooooooooooooooooooooooooooo
The hotel give 5 coins to the boy and keeps 25  still 30 coins in total
ooooooooooooooooooooooooo ooooo
The boy gives one coin to each of the men and keeps two
ooooooooooooooooooooooooo oo o o o
Still 30 in total
However if you look at the 27 coins that the men don't have you'll see that it includes the two coins in the boy's pocket. The misdirection is to suggest that adding these two coins to the "27" return us to the original 30 coins.

Re: An irritating little puzzle
OK, here's another little diversion. Needless to say, it took me longer than it really should have......
There is a very, very tall coconut tree and there are 4 animals, a Lion, a Chimpanzee, a Giraffe, and a Squirrel, who pass by.
They decide to compete to see who is the fastest to get a banana off the tree.
Who do you guess will win?

Insufficient data.
How did the banana get on the tree?
