Solution:The difference between the price at which a producer is ready to sell a commodity and the price at which he sells it is the producer's surplus.Minimum selling price of TV = Rs.7000
Notional cost of TV = Rs 12000
Actual selling price of TV = Rs 10500
Hence the surplus generated on the sale of TV ⇒ Actual selling price of TV - Minimum selling price of TV
⇒ 10500 - 7000 = Rs 3500
Hence, the producer surplus is Rs 3500.
