The Two Cars
Hi, everyone!
THE PROBLEM:
A man recently bought two cars, but afterwards found that they would not answer the purpose for which he wanted them. So he sold them for $1200 each, making a loss of 20%, on one car and a profit of 20%, on the other.
Did he make a profit on the whole transaction, or a loss? And how much?
Test yourself!

The First Problem
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?
