Just For Fun - The Missing Dollar

[kuiperbelt]

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 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 :)

There isn't one. There is $25 in the till, each guest has received a $1 refund, and the porter has a $2 tip = $30

classic misrepresentation. 25 in the jack and jill 1 in each of the 3 pockets +2 =30. Simples!

American quantitative easing in short.

"25 in the jack and jill 1 in each of the 3 pockets"

Should it not be, "each of the three skies"?

[bhg481]

What nobody has worked yet is the name of the third friend. TTT has worked out that one is called Jack and another is Jill but no mention of a name for the third one.

[DTCwordfan]

Well, well, bhg....

[ToraToraTora]

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.
