Well, about the cost of toothpaste idea. It depends on how you look at it. Say the toothpaste cost Mr. Y $2. Then he'd be out $8 bucks. But he already purchased the toothpaste at $2, which is finalized before the riddle takes place. Now he expects to sell it for $4, so that would make $10. So is he out what he paid for the toothpaste or is he out for what he would sell the toothpaste?

Mr. X goes to Mr. Y to buy toothpaste.

Mr. Y gives Mr. X the toothpaste and says it is $4.

Mr. X takes out his wallet and hands him $10 bill. (Is that fake?)

Mr. Y checks his cash register and finds that he has few $10 Bills and two $1 bills.

Mr, Y sends his assistant to Mr. Z to get change.

Assistant hands over $10 bill, which he got from Mr. X to Mr. Z. (Is that fake?)

Mr. Z hands him two $5 bills.

The assistant then hands that over to Mr. Y.

Mr Y puts one $5 bill back in the cash register,
takes out a dollar bill and along with the other $5 bill,
hands $6 back to Mr. X along with the toothpaste.

Mr. X walks away.

Mr. Z turns up at Mr. Y's and complains that the $10 bill his assistant gave was a fake.

Mr. Y hands another $10 bill from his cash register to Mr. Z.
(is that fake?)

So the question is :
How much was the monetary loss and to whom ?


Simplified, but then when I read through and noticed in the OP a grocer selling toothpaste - does that happen?

Keep in mind the toothpaste retails at $4 but is purchased at a lower cost price (whole sale)

Spoiler for assumption

There are fake notes going around and we should call the authorities - let them decide!

We can not assume there are no more fakes!

The OP clearly states that the assistant hands Mr. Z the $10 from Mr. X. If that is not the counterfeit 10, then we have to assume Mr. Z is lying and nowhere is anything said that should give that assumption.

The grocer could have gotten the toothpaste for $4 or $5 or even more. Many times grocery stores will take no profit or a loss on some products to get customers into the store so they can make profit on other products.

But regardless, if he had sold the toothpaste to someone else, he would have grossed $4, but since he practically gave it away, he is out $4 that he would have normally gotten, plus the $6 change for a total of $10

If grocers sell toothpaste?
If the toothpaste is a loss leader/fly-catcher?
If it was X,Y,Z or assistant (getting off lightly - he's my bet)

Call the authorities and let them sort it out.
