Just For Fun - The Missing Dollar
12 Answers
Three friends are on a road trip, and they rent a triple room for a night. When they get to the hotel, they pay the fee of $30 and go up to their room. The porter brings up their bags and refunds them $5 because the hotel is running a weeknight special. The three friends each keep one of the dollars and give the porter a $2 tip. Later, they sit down to work out their expenses for the weekend and find they have a problem.
They each paid $10 for the room and got $1 back each, making their contributions $9. Then they gave the porter a $2 tip. However, 9 times three is 27, plus two is $29. Where did the extra dollar go?

the other way to look at it is that they have each paid $9 so $27. $25 in the jack and jill and $2 in the porter's sky.

The maths is wrong, you should subtract the $2, not add it on.
Each friend paid £9 = £27, minus the $2 tip = the cost of the room ($25).
Or looking at it another way, the room cost $25, plus the $2 tip = $27, the amount that the friends paid.
It's a well-known puzzle that confuses people regularly :)
