3 men go into a motel. The man behind the desk said the room rent per night is $30, so each man paid (shared) $10 and went into to the room.

A while later the man behind the desk realized the room was only $25, so

He sent the bellboy to the 3 guys' room with $5.

On the way, the bellboy couldn't figure out how to split $5 evenly between 3 men, so he gave each man a $1 and kept the other $2 for himself.

This meant that the 3 men each paid $9 for the room, which is a total of

$27, add the $2 that the bellboy kept = $29.

So Where is the other dollar?

[Its a thought provoking riddle......... I managed to figure out the answer (barely and that too after 5 min). If you figured it out as well, post the answer in the comments section]
