Brain teaser or am I just stupid?
Saturday, November 4th, 2006Yesterday a co-worker asked me this brain-bang of a question and I am stumped. I hope I’m not overlooking something simple, but I’ve got to admit I’m questioning all existence.
It went like this:
Three businessmen were on a trip. They were tired and needed a place to stay for the night. One of the hotels they passed were offering a $30 a night special for one room. The businessmen thought that it would be wise to split the $30 and stay together.
The businessmen each paid the hotel clerk $10 a piece and headed up to their room. Moments later, the clerk realized that the hotel had a special that night of $25 a room, so he sent his assistant up with a $5 rebate all in $1 bills.
Once the businessmen answered the door, the clerk’s assistant realized that he couldn’t split the $1 bills evenly among the three and started to head back down to get change. The businessmen stopped him and said, “How about you give us each $1, leaving yourself a $2 tip?” After thanking the businessmen, the clerk’s assistant went on with his business, $2 richer.
The men returned to their beds, and being businessmen, they were happy to only be $9 in the hole instead of $10.
And this is where it got me. There was $30 in play. The men paid $10 a piece and got $1 a piece back… leaving the clerk’s assistant $2.
3 * 9 = 27, add 2 from the clerk’s assistant and you have = 29.
