Arter is a method of exchange whereby goods or services are traded directly for other goods or services without the use of money or any other medium of exchange. Suppose you need to get your house painted. You register with a barter Web site and want to offer your car cleaning services to someone who will paint your house in return. What are the problems you are likely to encounter?

Answer: correct evaluation and medium of exchange etc.

Explanation: The main problem with the barter system is that it would be hard to value the goods or services that the parties are exchanging. In the given case, it would be hard to value how many car washes would be equal to a paint of house.

Also finding someone who is willing to paint house in exchange of car washes is another difficult task.
