Q1. A digital-first startup has a fixed number of high-end servers (fixed factor) and is hiring programmers (variable factor). The company observes that after hiring the 6th programmer, the total lines of code written per day increase, but by a smaller margin than what the 5th programmer added. This situation is a classic example of:
Correct Answer: Option B (The second stage of the law of variable proportions)
Explanation: Effect of Y's price change: -1.5 * (+10%) = -15%. Effect of income change: 0.8 * (-5%) = -4%. The total net effect is -15% + (-4%) = -19%.
Q2. Consider two goods, X and Y. The cross-price elasticity between them is -1.5, and the income elasticity for good X is 0.8. If the price of good Y increases by 10% and simultaneously the consumer's income falls by 5%, what will be the approximate net effect on the demand for good X?
Correct Answer: Option B (Demand will decrease by 19%)
Explanation: This describes the core assumption behind the 'kinked demand curve' model of oligopoly, which explains why prices in such markets tend to be stable or 'sticky'.
Q3. In an oligopolistic market structure, firms often exhibit 'price rigidity'. Which of the following best explains this phenomenon from a strategic perspective?
Correct Answer: Option D (The cost of production for all firms in the industry is identical and constant.)
Explanation: The consumer equilibrium condition is MUx/Px = MUy/Py. Here, MUa/Pa = MUb/Pb. So, MUa/20 = 30/10. This gives MUa = 3 * 20 = 60 utils.
Q4. A consumer is in equilibrium, purchasing only two goods, Apples (A) and Bananas (B). The price of an Apple is ₹20 and the price of a Banana is ₹10. If the marginal utility of the last Banana consumed is 30 utils, what must be the marginal utility of the last Apple consumed?
Correct Answer: Option B (. The price of an Apple is ₹20 and the price of a Banana is ₹10. If the marginal utility of the last Banana consumed is 30 utils, what must be the marginal utility of the last Apple consumed?)
Explanation: Investment (I) is an injection as it adds to the aggregate demand and income in the economy. Savings (A) is a leakage, while consumption (C) and wage payments (D) are part of the flow itself.
Q5. Which of the following transactions would be considered an 'injection' into the circular flow of income in a two-sector economy?
Correct Answer: Option B (A firm decides to purchase new machinery for its factory.)
Explanation: Selling securities (OMO) withdraws liquidity from the system. The money multiplier is 1/CRR = 1/0.10 = 10. The total reduction in money supply is the initial withdrawal multiplied by the multiplier: ₹50,000 crore * 10 = ₹5,00,000 crore.
Q6. The Reserve Bank of India (RBI) conducts an Open Market Operation by selling government securities worth ₹50,000 crore to commercial banks. If the Cash Reserve Ratio (CRR) is 10% and there are no other leakages, what will be the ultimate impact on the money supply?
Correct Answer: Option C (Money supply will decrease by ₹50,000 crore.)
Explanation: A straight-line indifference curve signifies a constant Marginal Rate of Substitution (MRS), which is the characteristic feature of perfect substitutes.
Q7. If the shape of an indifference curve for two goods, 'Espresso' and 'Cappuccino', is a downward-sloping straight line, it implies that:
Correct Answer: Option B (The Marginal Rate of Substitution (MRS) between them is diminishing.)
Explanation: The primary deficit is calculated as the Fiscal Deficit minus Interest Payments. Therefore, Primary Deficit = ₹8 lakh crore - ₹3.5 lakh crore = ₹4.5 lakh crore.
Q8. The government's fiscal deficit is ₹8 lakh crore. The total interest payments on its accumulated debt amount to ₹3.5 lakh crore. This implies that:
Correct Answer: Option B (The primary deficit is ₹4.5 lakh crore.)
Explanation: The technological improvement only affects car production. This means the maximum quantity of cars that can be produced increases, while the maximum quantity of wheat remains unchanged. This causes the PPC to pivot outwards from the Y-intercept.
Q9. A technological advancement significantly improves the productivity of labour in the manufacturing of cars, but has no impact on the agricultural sector. How would this be represented on a Production Possibility Curve (PPC) with 'Cars' on the Y-axis and 'Wheat' on the X-axis?
Correct Answer: Option B (A pivotal outward rotation of the PPC along the Y-axis.)
Explanation: A firm in monopolistic competition has many close substitutes for its product, making its demand curve more elastic (flatter). A monopolist has no close substitutes, so its demand curve (the market demand) is less elastic (steeper).
Q10. A key difference between the demand curve faced by a firm in Monopolistic Competition and a pure Monopoly is that:
Correct Answer: Option C (The monopolistic competitor's demand curve is horizontal, while the monopolist's is downward sloping.)
Explanation: This is an export of services (tourism services), which brings foreign currency into India. It is therefore a credit (inflow) on the current account.
Q11. Which of the following would be recorded as a credit entry on the Current Account of India's Balance of Payments?
Correct Answer: Option C (A foreign tourist spends money on hotels and food in Jaipur.)
Explanation: If firms earn supernormal profits, new firms are attracted to the industry. This increases supply, drives down the price, and erodes profits until they return to the normal level (where Price = Average Cost).
Q12. In the long run, a firm operating under perfect competition earns only normal profits. The primary reason for this is:
Correct Answer: Option B (The government regulates the prices to ensure zero economic profit.)
Explanation: The investment multiplier (k) is 1 / (1 - MPC). Here, k = 1 / (1 - 0.75) = 1 / 0.25 = 4. The change in income is k * change in government spending = 4 * ₹200 crore = ₹800 crore.
Q13. In a Keynesian framework, if the Marginal Propensity to Consume (MPC) is 0.75, an increase in autonomous government spending by ₹200 crore will lead to:
Correct Answer: Option C (is 0.75, an increase in autonomous government spending by ₹200 crore will lead to:)
Explanation: This is the standard definition of the crowding-out effect. Government borrowing increases the demand for loanable funds, raising the 'price' of borrowing (interest rate), which discourages private firms from taking loans for investment.
Q14. The "crowding-out effect" of fiscal policy suggests that:
Correct Answer: Option B (A tax cut for the rich "crowds out" the benefits for the poor.)
Explanation: The formula is Real GDP = (Nominal GDP / GDP Deflator) * 100. So, Real GDP = (50,000 / 125) * 100 = 400 * 100 = ₹40,000 crore.
Q15. If the GDP Deflator for a country is 125 and the Nominal GDP is ₹50,000 crore, the Real GDP would be:
Correct Answer: Option C (₹50,000 crore)
Explanation: The theatre is dividing its customers into distinct groups (morning viewers vs. evening viewers) and charging different prices. This is a classic example of third-degree price discrimination based on time.
Q16. A local movie theatre offers tickets at ₹150 for morning shows and ₹300 for evening shows. This practice is an example of:
Correct Answer: Option C (Third-degree price discrimination)
Explanation: Higher inflation erodes the purchasing power of a currency. To maintain purchasing power parity, the currency's external value must fall, meaning it will depreciate against the currencies of low-inflation countries.
Q17. If a country's inflation rate is consistently and significantly higher than that of its trading partners, what is the most likely long-term impact on its currency under a flexible exchange rate system?
Correct Answer: Option A (The currency will appreciate.)
Explanation: This is a fundamental property of cost curves. The MC curve intersects the AVC curve at the AVC's minimum point. When MC < AVC, AVC falls; when MC > AVC, AVC rises.
Q18. When the Average Variable Cost (AVC) is at its minimum point, which of the following relationships holds true?
Correct Answer: Option B (Marginal Cost (MC) is at its minimum point.)
Explanation: A tractor is a capital good. The expenditure on it is investment spending, which is considered a final expenditure and is part of GDP. Steel (A) and paper (D) are intermediate goods. A second-hand good (C) is not included as it was counted when it was new.
Q19. Which of the following is an example of a final good and would be included in the calculation of a country's GDP?
Correct Answer: Option C (A second-hand textbook sold by a student.)
Explanation: An individual attempt to save more leads to less consumption. When everyone does this, aggregate demand falls, firms reduce production, and national income shrinks. This can lead to a situation where total savings actually fall or remain the same, hence the paradox.
