On his way to their room, the bellboy thinks, "They can't divide this money by 3, so I'll keep 2 and give them 3 back." He does so, and the guys are grateful for the rebate.

Here's the problem: the three guys have now paid 10 - 1 = 9 each, which is a total of 27. The bellboy kept 2, which makes 29. What happened to the other 1?
The other $2 is what takes you from 27 to 25...They paid $27 (3x$9) for a $25 room, so the other $2 is what gets them from $25 to $27. The $2 the bellboy kept is part of the 3x$9, not separate.
