Me too. We don't have those fancy toothpaste stores by me

the fake 10 dollar bill came from Mr. X

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 ?

Spoiler for Very old puzzle...
From Y's point of view...considering +ve as income and -ve as loss
Y got 0 dollars from X ( as fake dollars have no value)----> 0
Y took 10 dollars from Z in 5+5 (he gave the fake dollarwhich has no value)--->so +10
Y gave 10 dollars to X (6+toothpaste=4)--->So +10-10=0
Y gave 10 dollars back to Z---> 0-10= -10
So the loss is of Mr Y and the amount is 10 $. Its a very old puzzle and first I solved it with two of my brothers with real money, and a piece of paper (written $10 over it). Each of us had 50 $ before solving and after the solution I found I (y) have 40 $ and one of my brothers (x) has 60 $, we replaced the toothpaste with 4$.
But the basic is, net profit of the buyer=net loss of seller...

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