GDP and Welfare

The governing welfare measure is per-capita NDP, calculated as total NDP divided by population. Total NDP can rise while population grows at a faster rate; in that case, NDP per person falls and average material availability may decline. Therefore option A is correct. The other choices are not necessary conditions: depreciation need not be zero, exports need not stop, and taxes ending does not logically explain a lower per-capita output.

The governing concept is the limitation of conventional NDP as a welfare indicator. Market production generally increases measured NDP by ₹500 crore, but conventional accounting may not deduct the full external environmental cost. If damage is ₹650 crore, the unrecorded social loss can exceed the measured gain, so welfare may fall. Option A is correct; the other statements confuse output measurement with welfare or depreciation.

The governing concept is the limitation of conventional NDP as a welfare measure. Conventional NDP records the value of market production, so it rises by 700 crore rupees, but it does not automatically subtract every environmental cost. If the damage is 900 crore rupees, the social cost may exceed the production gain, causing net welfare to fall. Thus option A is correct; the other statements confuse output accounting with welfare accounting.

The governing relationship is GDP = NDP + depreciation, because NDP is obtained after deducting consumption of fixed capital from GDP. Since both countries have the same NDP, the country with greater depreciation will have the greater GDP after it is added back. Therefore, the first country is correct. Equal NDP alone does not imply equal GDP when depreciation differs.

Government schooling is generally a non-market service because it is not sold at a normal market price to students. In national accounting, such services are valued by their cost of production, especially the compensation paid to employees such as teachers, along with relevant operating costs. Thus option B is correct. Fees, building value and examination results do not measure the current flow of teaching service.

Per-capita NDP is an average: total NDP divided by population. An equal average can hide very different income distributions; one country may have greater inequality while the other distributes income more broadly. Welfare also depends on access to health care, education, public safety, leisure, and environmental quality, which the aggregate does not fully measure. Currency names, flags, and census dates do not directly determine welfare. Hence option A is correct.

Conventional NDP records the value of measured production, but it does not automatically subtract every environmental cost. Thus NDP may rise by 850 crore rupees even when environmental damage is 1,100 crore rupees. If that damage is considered, overall or net welfare may decline. Therefore, option A is correct. The other choices wrongly equate NDP with welfare or with ordinary depreciation.

Net indirect taxes are defined as indirect taxes minus subsidies: NIT = IT − S. Let indirect taxes and subsidies be 5x and 2x respectively. Their difference is 3x = ₹150 crore, so x = ₹50 crore. Therefore, indirect taxes = 5x = 5 × 50 = ₹250 crore. Option C is correct. ₹100 crore represents neither the stated tax amount nor the required ratio, while ₹375 crore incorrectly treats the full ratio total as the tax.

Use NIT = indirect taxes − subsidies. With the ratio 3:5, let taxes = 3x and subsidies = 5x. Then NIT = 3x − 5x = −2x. Since NIT is −₹80 crore, −2x = −80, giving x = ₹40 crore. Subsidies are therefore 5x = ₹200 crore, so option C is correct. The other choices do not preserve both the 3:5 ratio and the negative net amount.

The governing relation is that net indirect taxes equal the difference between market price and factor cost, and the numerical change must be calculated as final value minus initial value. Here, change = (-₹40 crore) − ₹160 crore = -₹200 crore. The negative sign means a decrease of ₹200 crore, so option C is correct. ₹120 crore would result from ignoring the negative final value.

Net indirect taxes equal market price minus factor cost. Initially, NIT = 4,200 − 3,880 = ₹320 crore. Later market price is ₹4,380 crore and factor cost is ₹3,950 crore, so NIT = 4,380 − 3,950 = ₹430 crore. The change is 430 − 320 = ₹110 crore increase. Option B is correct; the change depends on the difference between both increases, 180 − 70.

A base year provides the reference prices used to calculate real GDP and compare output across different years. Valuing current quantities at base-year prices holds prices constant, so changes in measured GDP more closely reflect changes in physical production rather than inflation. Therefore, option A is correct. Tax collection, imports, and population counting may be studied separately but are not the main purpose of a base year.

Real GDP values current-year output at base-year prices. Thus, the current quantity of 200 units must be multiplied by the base-year price of ₹12: 200 × ₹12 = ₹2,400. Option B is correct. The amount ₹3,000 is nominal GDP because it uses the current price of ₹15. This distinction prevents price changes from being mistaken for changes in actual production.

Real GDP values output using constant base-year prices, so it removes the misleading effect of general price changes. This makes comparisons of production across years more meaningful. For living standards, real GDP per capita is even more appropriate because it also accounts for population size. Therefore, option A is correct; exports, taxes, and population are not the reason real GDP is price-adjusted.

Real GDP per capita means the average amount of inflation-adjusted production associated with each person. It is calculated using the formula: Real GDP per capita = Real GDP ÷ Population. Therefore, real GDP must be divided by the population, making option A correct. Option C reverses the ratio, while B and D do not produce the per-person real output measure.

Real GDP per capita is calculated by dividing inflation-adjusted output by population. It therefore indicates the average amount of real production available per person and is commonly used as a broad indicator of average material living standards. Option A is correct. It is not a measure of population alone, the price level alone, or tax collection. However, it is only an average and does not fully capture inequality or non-market well-being.

Real GDP is designed to measure changes in production rather than changes in prices. By valuing goods and services from different years at the same base-year prices, the price effect is held constant and output quantities become comparable. Therefore option A is correct. Constant prices do not make all prices identical, stabilize money supply, or eliminate imports.

Real GDP measures the market value of final goods and services produced, adjusted for price changes. It does not fully include pollution, resource depletion, leisure, inequality or other non-market aspects of well-being. Thus, production can rise while environmental costs increase. Option A is correct; this limitation does not make real GDP useless or always incorrect.

Real GDP measures the total volume of production, not how income or output is distributed among households. If most gains go to a small group, average or total GDP can rise while many people experience little improvement in income or living conditions. Option A is correct. The other choices claim facts that cannot be inferred from aggregate real GDP alone.

Real GDP is useful because it measures the value of domestic output at constant prices, thereby removing much of the effect of inflation. However, welfare also depends on how income is distributed, unpaid household work, leisure, environmental quality, health and safety. Real GDP does not fully capture these dimensions. Therefore option B is correct; A, C and D contradict the meaning or use of real GDP.
