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 ?

Well, wouldn't Mr. X lose $4 b/c he bought a toothpaste?
Why is Mr. Y reimbursing Mr. Z? Mr. Z gave 2 $5 bills, not a $10.

How much was the monetary loss and to whom ?

More information is needed. Did Mr. X counterfeit the money himself? If so, then he made $10 (assuming it costs him nothing to produce a counterfeit bill). He has $6 in his pocket and $4 worth of toothpaste. Did he get passed the counterfeit money in another transaction and wasn't aware it was counterfeit? Then he made nothing and lost nothing. He exchanged a fake $10 bill (which he worked for or received fairly, making it irrelevant that it was fake) for $6 and $4 worth of toothpaste.

Mr. Y is out $10 as he assumed the responsibility for the fake (unless Mr Z is lying or incorrect) bill.

But the question isn't asking who made money/broke even, so your first paragraph is irrelevant.

Now the interesting questions are: Was there a fake $10? (Mr. Y simply took Mr. Z's word!) If there was a fake $10 where did it come from? (Mr. X, Mr. Y, the assistant (Mr. y?), or Mr. Z?

hmmmm .... Mr. X also got a change of $6 -- well, that will make it $10 loss to Mr. Y

The fake $10 bill came from Mr. X................
