If the receptionist gives one dollar to three people of five dollars and keeps two…add one plus one plus one plus two…that’s five.

There was no extra dollar, the problem isn’t right.
Three guys,
Each guy puts in 10 dollars,
each guy gets one dollar back,
the counter guy keeps the extra two.
Let 0 be the balance before he pays
0+10+10+10=30
30-1-1-1=27
27-2=25
There was no extra dollar, the problem was wrong.
Rather than subtracting the two dollars the counter guy pocketed they added, making the problem incorrect.
Ex.
0+10+10+10=30
30-1-1-1=27
27+2=29
Where did the last dollar go?

There’s a problem here all right. Even though nearly 30 plausible explanations are presented, Ashley states that written in a book was this same problem stating that there is no explanation.

The actual answer to this problem is that there is no answer. It is an old brain teaser that was made to make people think. I read this same teaser in an old book I have and it clearly stated that the problem is unsolvable.

So here’s the real answer.

Later that evening, two girls walked into the same hotel, and wanted to share a room. The receptionist makes the same mistake, and charges them $30, so they each payed $15, because 15 + 15 = 30.

They’re up in their room, and the guy realized that he’s made the same mistake, but this time he’s gotten a little greedier, so he gives them each $1, and keeps $3 for himself. So they’ve now payed $15 – $1, or $14 total.

$14 + $14 = $28, and $28 + $3 = $31.

And that’s where the extra dollar went.

I first came across this back in my college days (late 60’s). With a little practice, and a bit of slight of hand, I was able to get myself a free beer every Friday night.
I asked the patrons lay out $30 in singles on the bar. Made for a great bar story. It worked best, though, after everyone already had a few beers.

Why are you all so concerned about this?

The problem is that there is no extra dollar. The “extra dollar” is taken up by the fact that 24 and not 25 is divisible by 3. That, and the cashier is a thief.

You guys are overthinking this.

The moral of the story is: two guys to a room…MAX. Three guys to a room is grounds for expulsion from Mantown.

..the rest of this is null and void.
