Explanation: The fall in the price of a substitute (Good Y) will decrease the demand for Good X (shift left). The increase in consumer income (for a normal good) will increase the demand for Good X (shift right). Since the magnitude of these two opposing shifts is unknown, the final outcome on quantity is uncertain.
* Concepts Used: Determinants of Demand, Substitute Goods, Normal Goods.
* Type: High-level Application.
Q2. Consider the market for Good X, which is a normal good. In a particular month, two events occur simultaneously: the price of its closest substitute, Good Y, falls significantly, and the average income of consumers in the market increases. What will be the definitive net effect on the equilibrium quantity of Good X?
Correct Answer: Option B (The equilibrium quantity will decrease.)
Explanation: According to the Total Expenditure Method, when a fall in price leads to a fall in total revenue, the demand for the product is price inelastic. Consumers are not very responsive to the price change.

Correct Answer: Option B (₹7,100 crores)
Explanation: By summing up the 'value added' at each stage of production (Value of Output - Value of Intermediate Consumption), we ensure that the value of intermediate goods is not counted multiple times in the final national income.
* Concepts Used: National Income Calculation, Problem of Double Counting.
* Type: Conceptual, PYQ-based.
Q10. In national income accounting, the 'Value Added Method' is primarily employed to:
Correct Answer: Option A (Calculate the contribution of the tertiary sector only.)
Explanation: Initial credit creation = 50,000 * (1/0.10) = ₹5,00,000. New credit creation = 50,000 * (1/0.20) = ₹2,50,000. The decrease is 5,00,000 - 2,50,000 = ₹2,50,000.
* Concepts Used: Money Multiplier, Credit Creation.
* Type: High-level Numerical Application.
Q11. If the Legal Reserve Ratio (LRR) is increased by the central bank from 10% to 20%, what will be the impact on the total credit creation potential of the banking system, given an initial new deposit of ₹50,000?
Correct Answer: Option D (Total credit creation will increase by ₹50,000.)
Explanation: Margin requirement is a qualitative (or selective) credit control tool that allows the RBI to target lending for specific purposes without affecting the overall money supply. The other options are quantitative tools that have a general impact.
* Concepts Used: Monetary Policy Instruments (Qualitative vs. Quantitative).
* Type: Application-based, Tricky.
Q12. Suppose the Reserve Bank of India (RBI) wants to specifically discourage commercial banks from lending to the speculative real estate sector, without altering the overall cost of credit for other sectors. Which of the following instruments would be most appropriate?
