3 guys stayed in a hotel room. Each guy paid 10 dollars. The hotel cost 25 dollars. each man received 1 dollar back from the bellboy. Where did the other 2 dollars go?

That is the WRONG Question and answer.

I have received this question at my school and I got it right.

Think of it this way: 30 dollars were paid, 1 dollar was given back to each of the men, and the bellboy kept 2.

25+1+1+1+2=30

But when you think of it this way: Since each person paid 10 dollars and got 1 dollar back, they each paid 9 dollars. The bellboy has 2 dollars.

9*3=27+2=29 (where's the last dollar)

Here's the tricky part.

They paid 25 dollars together, not 30.

25/3=8.33 (They each paid 8.33)

25+2=27+3=30 (There you go, you got 30 dollars all together, they DID not each pay 9 dollars, they each paid 8.33 dollars.)
