TERMINAL EXERCISE

Q.1. What is meant by Price?

Ans. Price is the amount which a buyer pays for one unit of a good or service to the seller.

Q.2. What is meant by equilibrium price?

Ans. Equilibrium price is a price at which quantity demanded is equal to quantity supplied.

Q.3. What is meant by equilibrium quantity?

Ans. At equilibrium price, quantity determined and quantity supplied are equal. This quantity is called equilibrium quantity.

Q.4. How equilibrium price of a commodity determined?

Ans. Determination of equilibrium of price: The equilibrium price of a commodity is determined by the forces of demand and supply. At equilibrium price, the quantity demand of a commodity is equal to its quantity. In practical life, the price at which the seller/ firm wants to sell a commodity, its quantity supplied may be greater or lesser than its quantity demanded. Suppose at a given price, the demand is less than supply. It is the case of excess supply. In this case the price will fall. It will continue to fall till supply is equal to demand. Now suppose at given price, demand is more than demand. It is the case of excess demand. In this case, the price will continue to rise till the demand is equal to supply. In this way, equilibrium price is determined by the demand and supply forces.

Q.5. What happens to the price of a commodity when at a given price:

(a) Quantity demanded of a commodity is greater than its quantity supplied.

Ans. The price of the commodity increases.

(b) Quantity supplied of a commodity is greater than its quantity supplied.

Ans. The price of the commodity decreases.

(c) Quantity demanded is equal to its quantity supplied.

Ans. The price of the commodity does not change.

Q.6. How is the equilibrium price of a commodity affected when demand increases, but supply remains the same.

Ans. The equilibrium price of a commodity increases.

Q.7. Explain the effect of decrease in supply of a commodity on its equilibrium price and equilibrium quantity demanded and supplies when demand remains the same.

Ans. (i) Decrease in supply of a commodity will increase the equilibrium price of a commodity.

(ii) The equilibrium quantity demanded and supplied will decrease.
