Ok ....

X gives Y $10 which he trades with Z
Y gives X $6 back of his own $10 and keeps $4 for the paste
So right now Y + 4
Z comes and Y gives Z 10

Keep in mind monetary is defined by currancy and circulation; not product...

Spoiler for The real answer!!!

the fake 10 dollar bill came from Mr. X


ok X trades fake 10 for 2 real 5s - no value loss right now because it hasn't been discovered it's a fake.... even trade

Y keeps a 5 and gives the other 5 and one 1 of his own to X - ((5)+(-1)) = 4
Z discovers the fake and Y gives him $10

Now that everything is out in the open you can do the math

Spoiler for Math


The 10 is the cause of it but still a fake and has no value and doesn't exist.

This seems simple, but I am amazed with different answers I receive. Here it is:

A Man (Mr. X) goes to grocer (Mr. Y) to buy a toothpaste. The grocer (Mr. Y) gives Mr. X the toothpaste and says it is $4. Mr. X takes out his wallet and hands him $10 bill. Now the grocer (Mr. Y) checks his cash register and finds that he has few $10 Bills and two $1 bills. So he sends his assistant to the next door shop owner (Mr. Z) to get change. The assistant hands over $10 bill, which he got from Mr. X to Mr. Z. Mr. Z in turn hands him change of two $5 bills. The assistant then hands that over to the Grocer Mr. Y. The Grocer puts one $5 bill back in the cash register, takes out a dollar bill and along with the other $5 bill, he hands $6 back to our customer Mr. X along with the toothpaste. Mr. X walks away. After a few minutes, the next door shop owner Mr. Z turns up at the Grocer Mr. Y and complains that the $10 bill his assistant gave was a fake one and of no use. Mr. Y being a nice grocer apologizes and hands another $10 bill from his cash register to compensate to Mr. Z. So the question is : How much was the monetary loss and to whom ?

This does not work you put a cost value on an item that you do not know the orginal cost; so you are basing the monetary loss on a product that obviously cost less then person sold it for and his loss would be the cost to buy not to sell; and per definition that is not the question.... so $10 does not work.

What is so interesting is that simple math, and logic become confused, the more simple things are the more it is done to death, long way to go yet I'm sure. How do we know for sure where the fake is from if the grocer 'trusts' the man next door?

Scams all round!

Z comes and Y gives Z 10

Keep in mind monetary is defined by currancy and circulation; not product...

So X is down $6 and the product is irrelivant; I am sure he is insured.

How about the value of the toothpaste. Do you think Mr. Y got it for free? And yet he is going to pay tax assuming he sold it for $4.

So, the total loss on Mr Y must be $6+$4 = $10.
