Yes, and you answered that riddle right. But it's worded wrong, supposed to ask you this:
But it doesn't even make sense that way. When you calculate 9 X 3=27, that's already including the $2...they were supposed to pay $25, but he kept $2, so it's $27...plus the $2 that they already got back equals $30.

Technically they paid $9 each cuz they gave a $10 and got $1 back. but mathmatically they paid $9.33 each.
The room is $25/3=$8.33each.
$5 is given back, only 3 is recieved.
So out of $30 they all paid $9 for the room.

Hi. The first time I read it, I didn't get it either. But then I
realized that you just have to be REALLY careful about how you count
the dollars.
Let's give each of the $30 a number from 1-30, keep track of each
individual dollar, and see how the problem works.
Dollars numbered 1-30 are given to the manager. Then he wants to give
$5 back, so he keeps the dollars numbered 1-25, and gives numbers
26-30 to the bellboy in the form of a five dollar bill. The bellboy
splits up the five to get 5 one's: numbers 26, 27, 28, 29 and 30.
He gives numbers 26, 27 and 28 to the customers and keeps numbers 29
and 30 for himself.
