Three guys walk into a hotel and decide to split the cost of a room. The room is $30. They each pitch in $10 and head up to their room. The manager gets wind of it and tells the clerk the room is only $25. He hands five $1 bills to the bell hop and tells him to refund the guys' money.
On the way up to the room, the bell hop gets to thinking, as bell hops are wont to do, and says to himself, "No way can three guys split $5, I'm going to help out." He stuffs $2 in his pocket, knocks on the door, gives each guy back a buck and heads back downstairs to the desk, glowing in the warmth of a job well done.
So now each guy has paid $9. $9 times 3 is $27 plus the two the bell hop stole - only $29! Where is the other buck?

[b]SOLUTION[/b] The problem is actively misleading you. The men paid $10 each for the hotel room. 10 * 3 = 30 The actual cost was $5 less. 30 - 5 = 25 They are jointly refunded $3 and cheated out of $2. 25 + 3 = 28 28 + 2 = 30 There is [b]no[/b] missing dollar. The problem uses multiplication incorrectly to mislead you into believing that a dollar has gone missing.

There is no lost dollar because you are subtracting a dollar that isn't there.

Read my reply to your reply I got it rite?
-
You wouldn't be adding the $2 to the total, as they were subtracted. You'd add $3 to the total instead!
-
Your "logic" is flawed, as in the start of the puzzle you stated they each payed $10, so they didn't each pay $9. There is no lost dollar. The bellhop was handed $5 and took two, so he was left with $3. He handed a dollar to each. Done, simple.

Why were three guys booking a hotel room together?

Outside with the rest of the animals?
