The correct matching is: Flow variable → Defined over a period of time (c). Stock variable → Defined at a point of time (d). Gross investment → Addition of new machines over a year (a) because it measures total capital goods produced during a year. Capital stock → Capital preserved over time across production cycles (b). Therefore, the correct sequence is: 1-c, 2-d, 3-a, 4-b Hence, Option B is correct.

Statement 1 is false because maintenance reduces the effects of wear and tear but cannot eliminate depreciation permanently. Statement 2 is true because a portion of gross investment replaces worn-out capital goods. Statement 3 is true because all capital goods gradually experience wear and tear. Therefore, only Statements 2 and 3 are correct. Hence, Option C is correct.

The NCERT formula for net investment is: Net Investment = Gross Investment − Depreciation Depreciation represents the replacement of worn-out capital. Therefore, it is deducted from gross investment to determine the actual increase in capital stock. Option A correctly identifies gross investment. Option B is incorrect because depreciation is not deducted directly from capital stock. Option C is unrelated to capital formation. Option D concerns production inputs, not investment. Therefore, Option A is correct.

The logical lifecycle of a capital asset is: 1. A new machine is purchased. 2. It is used in production over several years. 3. Continuous use causes wear and disrepair. 4. Finally, it requires replacement. Thus, the correct order is: 3 → 2 → 1 → 4 Hence, Option D is correct.

The NCERT formula is: Net Investment = Gross Investment − Depreciation Given: Gross Investment = 500 units Depreciation = 50 units Net Investment = 500 − 50 = 450 units Thus, Option B is correct. Option A incorrectly adds depreciation. Option C ignores depreciation. Option D represents only depreciation.

The Assertion is true because net investment represents the actual increase in an economy's capital stock after accounting for depreciation. The Reason is also true because gross investment includes both replacement of worn-out capital and new capital formation. By deducting depreciation (replacement investment) from gross investment, we obtain net investment, which reflects only the new addition to capital stock. Formula: Net Investment = Gross Investment − Depreciation Thus, the Reason directly explains why net investment measures the actual increase in capital stock. Therefore, Option C is correct.

Using the straight-line depreciation method: Annual Depreciation = Cost of Asset ÷ Useful Life Given: Cost = Rs 2,000,000 Useful life = 20 years Annual Depreciation = 2,000,000 ÷ 20 = Rs 100,000 Therefore, Option A is correct. Option B overestimates depreciation. Option C greatly underestimates depreciation. Option D is obtained from an incorrect calculation.

The useful life of a capital asset refers to the expected number of years during which it can provide productive services. This estimate is used to calculate annual depreciation by spreading the asset's cost over its expected life. Option A is incorrect because market price is determined by demand and supply. Option B is incorrect because sudden destruction is not depreciation. Option C is unrelated to depreciation. Option D correctly identifies the purpose of estimating useful life. Therefore, Option D is correct.

Statement 1 is correct because depreciation is an accounting estimate of the annual wear and tear of capital goods. Statement 2 is incorrect because depreciation does not require an actual bulk cash payment every year. It is a non-cash accounting charge. Statement 3 is correct because, in a large economy, depreciation assumes a continuous flow of replacement investment as assets wear out over time. Therefore, Statements 1 and 3 are correct. Hence, Option B is correct.

The Assertion is false because depreciation is an accounting concept. It records the annual reduction in the value of fixed assets but does not imply that firms make an actual cash payment every year for the same asset. The Reason is also false because depreciation relates to expected wear and tear, ageing, and obsolescence. Sudden accidental destruction due to fire, floods, or earthquakes is treated as a capital loss, not depreciation. Therefore, Option A is correct.

The NCERT explains that an economy with a fixed level of total output must first recognize its resource constraint. If it decides to produce more capital goods, resources must be shifted away from consumer goods. As a result, fewer consumer goods are produced in the current period. The correct sequence is: 1. Output is limited. 2. Decision to produce more capital goods. 3. Resources are diverted from consumer goods. 4. Current production of consumer goods decreases. Thus, the correct order is: 1 → 2 → 3 → 4 Therefore, Option C is correct.

The correct matching is: Total Output → Includes both consumption and investment goods (b). Consumer goods → Used for final consumption by the population (d). Capital goods → Used to maintain or add to capital stock (c). Trade-off → Choice between producing consumer goods and capital goods (a). Therefore, the correct sequence is: 1-b, 2-d, 3-c, 4-a Hence, Option D is correct.

Producing more capital goods today increases the economy's stock of productive assets. These assets enable workers to produce more goods and services in the future, thereby increasing the economy's production capacity. Option A correctly identifies the long-run benefit. Option B is incorrect because immediate consumption may actually decrease during investment. Option C is unrelated to economic growth. Option D has no connection with capital formation. Therefore, Option A is correct.

Sophisticated machinery and equipment help workers produce more goods in less time. They increase labour productivity by making production faster and more efficient. Option A is incorrect because capital goods do not directly reduce wages. Option B correctly identifies the productivity effect. Option C is incorrect because machinery supports production rather than stopping it. Option D is incorrect because labour cannot become an intermediate good. Therefore, Option B is correct.

The correct matching is: Short-run trade-off → Less consumer goods today (a). Long-run benefit → More consumer goods tomorrow (d). Constant total output → Assumption for the current trade-off (c). Increased total output → Result of more future capital (b). Thus, the correct sequence is: 1-a, 2-d, 3-c, 4-b Hence, Option D is correct.

Capital formation increases the economy's stock of productive assets, leading to long-run economic growth. Statement 1 is incorrect because higher capital stock does not reduce future consumption. Instead, it enables greater production of both consumer and capital goods. Statement 2 is correct because improved machinery and equipment enable the same labour force to produce more output. Statement 3 is correct because increased capital stock raises the economy's productive capacity in the future. Therefore, only Statements 2 and 3 are correct. Hence, Option C is correct.

Capital goods such as machines, buildings, and tools are durable assets used repeatedly in production. They remain part of the capital stock and gradually lose value through wear and tear. Option A is incorrect as a characteristic because immediate consumption describes non-durable consumption goods, not capital goods. Option B is a correct characteristic. Option C is correct because capital goods constitute capital stock. Option D is correct because capital goods depreciate gradually. Since the question asks for the statement that is NOT a characteristic, Option A is correct.

Investment in capital goods increases the economy's stock of productive assets. As more machinery, equipment, and infrastructure become available, productive capacity expands, allowing the economy to produce more goods and services in the future. Option A is incorrect because capital formation does not shrink capacity. Option B correctly reflects the NCERT explanation. Option C is incorrect because investment supports continued production. Option D is unrelated to economic expansion. Therefore, Option B is correct.

The passage explains the circular relationship between production and consumption. Production generates factor incomes (wages, rent, interest, and profit), and these incomes provide households with the purchasing power to buy final consumption goods. Option A is incorrect because reducing factor payments lowers purchasing power. Option B is unrelated to consumer demand. Option C concerns inventory, not purchasing capacity. Option D correctly reflects the passage. Therefore, Option D is correct.

The passage states that capital goods are purchased by business enterprises to maintain existing capital stock or add to it. This enables future production by increasing productive capacity and replacing worn-out assets. Option A is incorrect because capital goods remain actively involved in production over many years. Option B is incorrect because households consume consumer goods, not capital goods. Option C correctly reflects the passage. Option D is incorrect because production continues to require factor payments. Therefore, Option C is correct.
