How surplus farm products is sold by the farmers?
Answer:
Let us assume that farmers have produced wheat on their land. They retain a part of the wheat for the family consumption and sell the surplus wheat. Small farmers like Savita have little surplus wheat because their total production is small and from this a substantial share is kept for their own family needs. The medium and large farmers supply wheat to the market which the traders buy and sell it further to shopkeepers in the towns and cities.
