Once there was self reliance market where people had limited wants and never had the opportunity or need for trade. But as the time passed on, the needs increased and they introduced the concept of barter system, where people exchanged their goods for other’s goods. This had a greater chaos and confusions as exchange of goods had complexion. For example, if a needs banana and ready offer meat, he needs a barter that is ready to accept meat and give him bananas. This also had another problem of value, for the value of meat is not equal to the value of banana.
