Missing Dollar Puzzle: 3 guys rent a room at $30 - Where is the One dollar?

Three people rent a room at $30. They pay $10 each and go up to the room. The owner realized he charged too much and it was only supposed to be $25. He sends a boy up with the $5. Each of the people keeps $1 and they give the boy $2 as they can't share it. 

So now each person has paid $9 for the room (total $27) and the boy has $2.

Where is the other $1?

The $1 was with the owner .

After giving $5 to boy,the money owner had is $25.    

So owner had charged $8dollars for each and $1 extra.($25/3=$8+$1)

Hope the problem was solved.

It is true that the three paid $27.

 $25 are with the owner and $2 with the boy. That is all.

There's nothing much to solve here, I think. They paid $25 to the owner and $2 to the boy. 

PS: Another version of the same problem had confused the hell out of me (about 20 years ago, though 😮 )

Right!! 

Owner gets ----- $25

Boy Gets --- $2

Each person paid = $25 + $2 = $27. 😎 😎
