Deciding whether resources go into education/health or military is a choice about which goods/services and in what quantity to produce. This is the 'What to produce' central problem of allocation.
Show answer & explanation
Correct answer: C
NCERT defines the collection of ALL possible combinations of goods producible from given resources and technology as the Production Possibility Set. The frontier (PPF) is only the boundary of this set.
Show answer & explanation
Correct answer: A
Wait—logical sequence on a leftward demand shift: first (A) at any given price demand is less, leading to (B) excess supply, then (C) producers cut prices, finally (D) new equilibrium with lower price and quantity. That is (A),(B),(C),(D), which is not an option. Among options, (A)=(B),(A),(C),(D) places excess supply then less demand then price cut then new equilibrium — closest valid causal chain ending correctly at (D). Selecting (A).
Show answer & explanation
Correct answer: B
(A) utility expressed in numbers = Cardinal Utility (I); (B) change in total utility per additional unit = Marginal Utility (III); (C) MU declines as consumption rises = Law of Diminishing Marginal Utility (II); (D) goods foregone keeping utility same = Marginal Rate of Substitution (IV). Matches option B.
Show answer & explanation
Correct answer: D
NCERT: the budget set is the set of all bundles available to (affordable by) the consumer given prices and income. Option D states this. B describes a single affordable bundle, not the set.
Show answer & explanation
Correct answer: A
(A) correct: jointly consumed goods are complements. (C) correct: price elasticity measures responsiveness of demand to price. (B) wrong: market demand is HORIZONTAL summation. (D) wrong: favorable preference shift moves demand RIGHTWARD. So only (A) and (C).
Show answer & explanation
Correct answer: B
The relation between a consumer's optimal (chosen) quantity of a good and its price is the demand function.
Show answer & explanation
Correct answer: A
(A) relation between variable input and output = Total Product (IV); (B) output per unit of variable input = Average Product (I); (C) change in output per unit change in input = Marginal Product (II); (D) MP initially rises then falls = Law of Variable Proportions (III). Matches option A.
Show answer & explanation
Correct answer: B
In the long run all factors of production are variable; there are no fixed factors. This distinguishes it from the short run.
Show answer & explanation
Correct answer: D
Profit = Total Revenue - Total Cost. The difference between revenue and cost is profit.
Show answer & explanation
Correct answer: A
Marginal Product = change in output per unit change in one input, holding other inputs constant. $MP = \Delta Q/\Delta L$.
Show answer & explanation
Correct answer: C
Decreasing returns to scale: scaling inputs by $t$ raises output by less than $t$ times, i.e. $f(tx_1,tx_2) < t\,f(x_1,x_2)$. Option C. (B = constant returns, D = increasing returns.)
Show answer & explanation
Correct answer: D
Change in total cost per unit change in output is Marginal Cost. In short-run context this is the Short Run Marginal Cost. $SMC = \Delta TC/\Delta q$.
Show answer & explanation
Correct answer: C

Show answer & explanation
Correct answer: B
MC cuts AC at AC's minimum point. When MC<AC, AC falls; when MC>AC, AC rises; they are equal at the lowest point of AC.

Correct answer: A
The point where the firm earns only normal profit (price = minimum average cost, zero economic profit) is the break-even point.
Show answer & explanation
Correct answer: D
Profit-maximising conditions for a competitive firm: (A) P = SMC; (B) SMC is non-decreasing at that output; (D) P >= AVC (so production is worthwhile). (C) P<=MC is wrong. So (A),(B),(D) — option D.
Show answer & explanation
Correct answer: A
Technological progress lowers costs, increasing supply at every price, so the supply curve shifts rightward.
Show answer & explanation
Correct answer: C
$\%\Delta Q = \frac{24-30}{30}=-20\%$; $\%\Delta P = \frac{14-10}{10}=40\%$. Elasticity $= |{-20\%}/{40\%}| = 0.5$.

Show answer & explanation
Correct answer: B
This is the Paradox of Thrift: a general rise in saving rate lowers income so much that total saving does not rise.
Show answer & explanation
Correct answer: B
CPI compares the cost of the basket in the current year against the base year: $CPI = \frac{\text{cost in current year}}{\text{cost in base year}}\times100$. Only current and base years are used.
Show answer & explanation
Correct answer: A
The price index of a basket of commodities bought by a representative consumer is the Consumer Price Index (CPI).
Show answer & explanation
Correct answer: B
(A) GDP_MP = C+I+G+(X-M) = (III); (B) NDP_FC = NDP_MP - net product taxes - net production taxes = (I); (C) GVA at FC = GVA at basic prices - net production taxes = (II); (D) GNP_FC = GNP_MP - net product taxes - net production taxes = (IV). Matches option B.
Show answer & explanation
Correct answer: D
GDP measured at constant (base-year) prices is Real GDP; at current prices it is Nominal GDP.
Show answer & explanation
Correct answer: A
Functions of money: medium of exchange (A), unit of account (B), store of value (D). Bartering (C) is what money replaces, not a function. So (A),(B),(D).
Show answer & explanation
Correct answer: C
Deposits are owed by the bank to depositors, so they are liabilities of the bank.
Show answer & explanation
Correct answer: D
(A) CRR = % of deposits kept as cash reserve with central bank = (III); (B) SLR = reserves in liquid form (short term) = (IV); (C) Lender of last resort = Central Bank = (I); (D) Repo Rate = interest rate at which central bank lends = (II). Matches option D.
Show answer & explanation
Correct answer: A
Currency notes and coins are accepted as money by government fiat (legal tender, not backed by commodity), hence called fiat money (also legal tender).
Show answer & explanation
Correct answer: A

The passage states 'The equilibrium output in the economy also determines the level of employment.' Hence level of employment is determined by output equilibrium.
Show answer & explanation
Correct answer: C
Passage: 'Full employment level of income is that level of income where all the factors of production are fully employed in the production process.' Option C is verbatim.
Show answer & explanation
Correct answer: D
Passage: 'the level of output determined by the equality of Y with AD'. So output is determined by equality of income (Y) with aggregate demand (AD).
Show answer & explanation
Correct answer: A

Show answer & explanation
Correct answer: D
Among these, petroleum, alcohol and tobacco products lie outside/partly outside GST; tobacco also attracts central excise over and above GST, so it is treated as kept out of the pure GST ambit. Gold and silver are within GST. Option D.
Show answer & explanation
Correct answer: C
Passage: GST 'is applicable throughout the country with one rate for one type of goods/service' establishing 'parity in taxation across the country' — uniform tax rate nationwide makes it a unified system. Option C.
