the answer is, the original room bill was 30, but it got cut down to 25 pounds. that means that each person didnt pay exactly 9 dollars. if you calculate it, each person payed 8.33 pounds to the room, and two went to the waiter. (8.33x3) + 2 = (25) + 2 = 27. the remaining three pounds, which were returned to the people, couldn't be divided equally because the waiter didn't have change.

person 1: paid 8 for the room, recieved 1 pound back (9)
person 2: paid 8 for the room, recieved 1 pound back (9)
person 3: paid 9 for the room, recieved 1 pound back (10)
waiter : stole 2 bucks (2)

9+9+10+2=30 the other pound was in the hotel safe, cuz person 3 got screwed over and had to pay 1 pound more than his friends.

the 10-1=9
10-1=9
10-1=9
equation is misleading, since it makes you think that they had paid 9 pounds each. it is actually 30-3 (27) then 27-2 (25) the cost of the room. you think that you are supposed to ADD the two pounds the waiter took, rather than subtracting it, which you should have done.
