Frequently Asked Questions
What was the biggest problem in the barter system?
The biggest problem was the lack of a 'double coincidence of wants', meaning finding someone who both wanted what you had and had what you wanted was very difficult.
Why did people stop using commodity money like grains and cattle?
Commodity money was difficult to store, lacked uniform quality, and perishable items like grains could rot or get damaged easily over time.
Why are paper notes accepted as money if they are just paper?
Paper notes are authorized and guaranteed by the government and the Reserve Bank of India (RBI), making them legal tender that everyone must accept.
