Let us consider the example of a market consisting of identical farms producing the same quality of wheat. Suppose the market demand curve and the market supply curve for wheat are given by: qᵈ = 200 - p and qˢ = 120 + p. What is the equilibrium price?

Solution

✅ Correct Option: 1

Option 1: Rs. 40 per kg -> At equilibrium, quantity demanded equals quantity supplied (qᵈ = qˢ). Setting 200 - p = 120 + p, we get 200 - 120 = 2p, which gives 80 = 2p, so p = 40. At this price, both qᵈ and qˢ equal 160 units, confirming market equilibrium where there is no shortage or surplus. -> correct
