So, the buyer comes to the store, and wants to buy a hat for 10 roubles.
He is paying with a 25 rouble bill, and the seller doesnt have the change.
He sent a boy to the next store to change it.
The boy came back with 2 ten and one five rouble bills.
The seller sold the hat and gave 15 roubles in change.
The person from the next store comes in and says that 25 roubles note was a fake, and gets his money back.

The question is, how much money did he loose?

[TWilliam]

50 roubles.

10 for the hat.

15 given in change.

25 he must now refund to the other store owner.

Pretorian, you also need to specify what his inventory is.

If he has a whole store full of hats, his shrinkage loss is his wholesale cost of the hat.

If it was the last one left on display, and another customer walks in to buy a hat, he incurs a lost opportunity cost. He loses the opportunity to earn the retail profit on the hat

There is also an intangible loss of "goodwill". Locals may gossip what a fool the store owner is and take there business elsewhere. It's hard to quantify goodwill.

[ECM]

The seller is out the cost of the hat at minimum + 15 roubles.

The two transactions with the person next door nullify each other.

[cynicalheretic]

Actually he lost nothing. He later found the thieves and beat the crap out of them till he got his money back

[Falconoffury]

35 roubles total. He lost 10 roubles when he bought the hat, and 25 roubles to pay back the moneychanger.

Assuming he had another 25 rouble bill in his pocket that the moneychanger inspected carefully and determined to be legitimate.

[PenultimateManStanding]

$this->bbcode_second_pass_quote('Falconoffury', '3')5 roubles total. He lost 10 roubles when he bought the hat, and 25 roubles to pay back the moneychanger.

[eastbay]

He got his 25 Roubles back Therefore he didn't lose anything. What a stupid question. My IQ is about 80 and, although this quiz was restricted to those with an IQ over 90, even I got it right.

PEAK HATS

It's true I suppose he could decry
The profit lost when they came to buy
seven ruble hats from a vast supply
but now you can't even get 'em.

[Falconoffury]

You guys assume too much. Nowhere does it say he returned the hat for a refund. It doesn't say that the 25 rouble note was the only money the guy had to begin with. It also doesn't say that the moneychanger gave back the alleged counterfeit note.
