I read this riddle last night and it wouldn't let me sleep. Maybe somebody knows the solution:
There are three travelers getting a shared hotel room for 30 dollars. Each pays 10 dollars. Later, the receptionist realizes that there is a discount for that room, it costs 25 only.
She gives 5 dollars to the bell boy to bring to the travelers. Because he didn't get a tip he gives them only 1 dollar each and keeps 2 dollars in his pocket.
So each traveler payed 9 dollars (27 dollars together) and the bell boy keeps 2 dollars. Where is the remaining dollar???
