This riddle became so popular in my country later so I'm gonna tell u it and let u try to solve it xD
Here we go
A money thief had a fake 100 $ he went to a shop and bought from it's owner a newsletter that costs 10$ as he gave the fake 100$ to the shop owner the shop owner didn't have 90$ he had only solid money so he went to a cafe and gave it's owner the fake 100$ solid and took ten 10$(which means 10 x 10 = 100 x3 ) then the shop owner gave the thief the rest of his money which are 90 $ then after a while the cafe owner came to shop owner and told that 100$ he gave to him is fake so the shop owner gave him another 100$
How much did the shop owner lose?
(I shall answer it after a while xD) if you are confused write in the comments and I will answer (i'm not that good at writing in meaning xD)
The store owner starts with 0 of his own money before the thief comes into play. He gains 100 in 10s from the cafe owner. Then he loses 90 in 10s to the thief. Then he loses 100 to the cafe owner.
Roughly speaking, p * 10 will be just below the cost the store owner has to buy the newspaper for, assuming he's an efficient store owner.

The lost profit is tangible.

he bought the newspaper to resell the newspaper, he lost money on the trade. he lost 200 dollars. he gave the theif the paper + 90 real dollars and then had to pay back the cafe shop owner another 100 dollars.
he lost 190 plus the paper. you are wrong.

Yeah but him buying the newspaper in the first place has nothing to do with the riddle.

That $10 lost profit isnt tangible, so $$ didn't physically go anywhere. What happens if the store was demolished before that 'lost newspaper' sold
If you wanna get technical, the price of the newspaper to the store owner is p * 10 where p is the probability someone comes in by the end of the day to buy a newspaper, and he has sold all his newspapers. Estimation of p will be used to determine how many newspapers the store owner buys from his supplier.
store owners dont buy things for the same price they sell them.

It's a hypothetical situation. Obviously nobody would buy or sell a newspaper for ten dollars. Also, for example, let's say you run a donut shop. If you're supposed to have 100 donuts to start the day which are one dollar each, but you're missing two for whatever reason, you're at a two dollar deficit already. Any good owned by someone has a monetary value
