Title: Quick little math riddle
Post by Galactic on Feb 17^th, 2003, 7:32am

Ok here goes:

3 guys go to a hotel. They get 1 room for the 3 of them. The total comes out to 30 dollars.

So each man pays 10 dollars. ($30)

Then the hostess tells them there is a special discount on that day, so they get 5 dollars back. ($30 - $5 = $25)

So they decide to each take a dollar and leave 2 dollars for the cleaning maid as a tip. ($5 - $3 - $2 = 0)

Now seeing as how the each originally paid 10 dollars and they each got 1 dollar back, logically each one of them paid 9 dollars.

Now it's kind of impossible. 9 x 3 = 27, yet they only left 2 dollars as tip... 27 + 2 = 29.

Any ideas on how they did this?

Well, at least I have an idea of how to use the search feature (http://www.ocf.berkeley.edu/~wwu/cgi-bin/yabb/YaBB.cgi?board=;action=search).
Please post to the existing thread (http://www.ocf.berkeley.edu/~wwu/cgi-bin/yabb/YaBB.cgi?board=riddles_hard;action=display;num=1027807243) if anybody has anything meaningful to add.

each guy pays 10 bucks = 30
5 dollar discount = 25
3 bucks between the guys = 28
2 bucks for maid = 30
