Key concepts: The Price Puzzle: What Drives the Market (Class 9 Social Science)

Prices are not set by anyone in particular; they emerge where the intentions of buyers and sellers meet. This chapter builds demand and supply, explains why each slopes as it does, and shows how equilibrium price is reached and why it shifts.

Market
Any arrangement that brings buyers and sellers into contact, whether a physical marketplace or an online platform.
Demand
The quantity of a good buyers are willing AND able to purchase at a given price in a given period — willingness alone is not demand.
Law of demand
Other things being equal, a rise in price reduces the quantity demanded and a fall in price raises it, giving a downward-sloping demand curve.
Determinants of demand
Besides price: income, the prices of substitutes and complements, tastes, expectations and the number of buyers.

    Assertion (A): If coffee becomes more expensive while the price of tea stays the same, the demand for tea may increase. Reason (R): Tea and coffee are complementary goods, which are generally used together.

    B.Both A and R are true but R is not the correct explanation of A
    C.A is true but R is false✓ Correct
    D.A is false but R is true

    Answer: C. A is true but R is false

  13. Q13Hard

    A demand schedule for ice cream shows: at Rs 30, 100 cups; at Rs 40, 80 cups; at Rs 50, 60 cups. These numbers are consistent with the law of demand because:

    B.As price rises, quantity demanded rises
    C.Quantity demanded does not change
    D.Price and quantity demanded both fall together

    Answer: A. As price rises, quantity demanded falls

    Explanation: The schedule shows quantity demanded falling (100 to 80 to 60) as price rises (30 to 40 to 50), which is the inverse relation of the law of demand.

  14. Q14Hard

    Read the case: 'Market forces would settle the price of a pulse at ₹90 per kg, but the government fixes a maximum price of ₹60 per kg.' Which outcome does the chapter warn such a measure can lead to?

    A.Producers lose motivation to supply, which may lead to reduced production and shortages✓ Correct
    B.Producers expand output to earn more, creating a surplus
    C.The price floor raises producers' incomes above the market level
    D.The market quickly settles at the equilibrium price of ₹90 per kg

    Answer: A. Producers lose motivation to supply, which may lead to reduced production and shortages

    Explanation: A maximum price set below the market level is a price ceiling. The chapter warns that when the government fixes prices below market levels, producers may lose motivation to supply, which may lead to reduced production and shortages. A price floor is a minimum limit, such as a minimum wage, not a maximum.
