A riddle!?

3 men walk into a hotel for the night, They each pay 10 dollars for a room.
The 3 men go upstairs and relax in their room.
The manager over charged by 5 dollars, So he goes to return the 5 dollars to the 3 guys.
Noticing he cannot divide 5 by 3 evenly, He gives EACH man 1 dollar, and keeps 2 dollars.

So if each man paid 9 dollars for the room, since they had paid 10 and got 1 back,
and the manager kept 2, where did the other dollar go?

9 * 3 = 27 + 2 = 29 not 30.

I'll give you the answer in a week if no one gets it, but since everyone here is so smart, i shouldn't have to Smile
Good Luck!

Well, overall their rooms were suppose to cost $25, and they got $3 dollars return, and $2 dollars pocketed, thus making $30.
Because they do not pay their refund, they pay what the manager+hotel has which is 27 overall (30-3), and they have the 3 dollars in their pockets.
Thus it is suppose to be 9*3=27+3=30, cause what they paid includes what the manager has in pocket Smile

Very Easy Smile

there is an easier way to look at it heres the math way

they each were supposed to pay for the night 25/3 (they were charged 5 dollars more for 30) per person,

now if they are each refunded one dollars

25/3 + 1/1 = 25/3 + 3/3 = 28/3

now there are 3 people

so we have (28/3)*3 + 2 that the manager kept

which is 28 + 2 = 30

They did not pay $9 for the room. The truth is that they paid $25/3 for the room and $2/3 of the $2 that the manager has. The equation is 25/3*3 + 2/3*3 = 27. Where did the other 3 dollars go? They got it back--$1 each.
