... and it's $30 a night all three guys slept in the same room so each of them paid $10 , the owner of the hotel called the room service guy and told him here take $5 and give it to the three guys he went and when he got to there room he didn't know how to divide the $5 so he gave each one of them $1 now each paid $9 since they got a $1 back now 9*3= $27 and the room service guy has $2 that's $29 in total where did the $1 go???????
P.S whoever solves it gets a gift from me
