The Problem about a salesman

Hi, everybody!

THE PROBLEM:
A salesman sells caps. One cap costs $20. A buyer agreed to purchase it, but he had only banknote $50. The salesman sent a boy with that banknote $50 to the neighbour to change. The boy came and gave $20+$20+$10. The salesman gave a cap and $30’ change. Not long after the neighbour came and told that $50 was bad money, demanded his money back. The salesman climbed in a cashdesk and returned him $50.

What loss was suffered by a salesman?

Re: The Problem about a salesman

It depends on how you look at it.  Cash-wise he's down 30$ from where he started, but he's also down a cap.  If you count the cap as a loss, which I would, he's down $50 total, which makes sense.  He sold a $20 cap for $20, so he broke even on that exchange, but then the neighbor demanded his $50, so that's a $50 loss.

You are absolutely right! He's down $50 total.
