Methods of calculating national income - Value Added/Product Method
राष्ट्रीय आय की गणना की विधियाँ – मूल्य वर्धित/उत्पाद विधि
In this Class 12 Economics topic from the chapter “National Income and Related Aggregates,” students learn how national income is estimated through the Value Added or Product Method. The topic explains how to measure the value of final goods and services produced by different sectors, calculate value added at each stage of production, and avoid double counting of intermediate goods. It also connects production data with aggregates such as GDP and helps students understand the role of primary, secondary, and tertiary sectors in national income accounting.
Practice questions
01 If a firm gives part of its produced goods to employees as payment in kind, how should those goods be treated in the value of output?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. They will be included in the value of output
Explanation: Goods supplied to employees as remuneration in kind are still part of the firm’s current production. Their value is included in output, even though the firm does not receive a separate cash sale. The same transaction is also recorded as compensation of employees in kind, preventing the output from being omitted.
02 In the value added method, how may a normal business insurance premium paid by a producer to an insurance company be treated?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Intermediate service consumption
Explanation: A normal business insurance policy provides risk-cover and related services used by the producer in conducting production. The premium is therefore treated as payment for an intermediate service and deducted as intermediate consumption when calculating the producer’s value added. It is not wages or capital formation.
03 A producer spends ₹80,000 on ordinary factory-building repairs and ₹9,00,000 on constructing a new building. Which item is more appropriately treated as intermediate consumption in value added?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Ordinary repair expense
Explanation: Ordinary repairs merely maintain an existing factory and are a current service input used in production, so they can be treated as intermediate consumption. A newly constructed building provides productive assets over several years and is therefore fixed capital formation. It is not deducted as an intermediate input.
04 A producer paid raw material ₹7 lakh, packing ₹1 lakh, outsourced IT service ₹2 lakh, wages ₹5 lakh and interest ₹1.5 lakh. What is intermediate consumption?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. ₹10 lakh
Explanation: Intermediate consumption includes goods and services used up during the production process: raw material of ₹7 lakh, packing of ₹1 lakh, and outsourced IT service of ₹2 lakh. Thus, intermediate consumption equals 7 + 1 + 2 = ₹10 lakh. Wages and interest are payments to factors of production and are included in factor incomes, not intermediate consumption.
05 In the value added method, what is the correct classification of an outsourced legal advisory fee for a producer?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Intermediate service consumption
Explanation: An outsourced legal advisory fee is payment for an external professional service used by the producer in conducting or supporting production and business operations. It is consumed as a current input rather than creating a lasting productive asset. Therefore, it is classified as intermediate service consumption and is deducted from the value of output when calculating GVA.
06 Value added in three successive stages is ₹55,000, ₹72,000 and ₹48,000. If the retail trade margin is ₹25,000, what is the value of the final good?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. ₹2,00,000
Explanation: The value of the final product is obtained by adding the value created at every stage of production, including the retail trade margin. Therefore, final value = ₹55,000 + ₹72,000 + ₹48,000 + ₹25,000 = ₹2,00,000. Adding value added avoids counting the same intermediate product repeatedly.
07 A security-service company receives a fee of ₹1,20,000, spends ₹18,000 on the consumption of uniforms and equipment, and pays guards’ wages of ₹75,000. What is its GVA at market price?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. ₹1,02,000
Explanation: For a service firm, the fee received represents the value of output. GVA at market price equals output minus intermediate consumption. Uniforms and equipment consumed in providing the service are intermediate inputs, so ₹1,20,000 − ₹18,000 = ₹1,02,000. Wages are factor payments and are not deducted when calculating value added.
08 What is the most important care while including imputed rent of an owner-occupied house in national income?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Treat it as an estimated housing service, not as cash rent
Explanation: An owner-occupied house provides housing services even though the owner does not pay rent to another person. National-income accounting therefore records an imputed rent as the estimated value of that service. It is a notional transaction, not actual cash income, and it is not intermediate consumption or the sale of an asset.
09 The value of output is ₹32 lakh and GVA at market prices (GVAₘₚ) is ₹13.5 lakh. If intermediate services cost ₹4.2 lakh, what is the value of intermediate goods used as inputs?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. ₹14.3 lakh
Explanation: Under the value-added method, GVA equals the value of output minus total intermediate consumption. Therefore, total intermediate consumption is ₹32 lakh − ₹13.5 lakh = ₹18.5 lakh. This total includes both intermediate goods and intermediate services. Since services account for ₹4.2 lakh, intermediate goods input is ₹18.5 lakh − ₹4.2 lakh = ₹14.3 lakh. Hence, option A is correct.
10 A producer pays ₹4,40,000 for raw materials, ₹60,000 for ordinary machine repairs, ₹3,00,000 as wages, ₹1,20,000 as rent and ₹80,000 for fuel. What is intermediate consumption?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. ₹5,80,000
Explanation: Intermediate consumption includes goods and services used up during production. Here, raw materials ₹4,40,000, ordinary repairs ₹60,000 and fuel ₹80,000 are intermediate inputs. Wages and rent are factor payments, not intermediate consumption. Hence, total intermediate consumption is ₹4,40,000 + ₹60,000 + ₹80,000 = ₹5,80,000.
11 How should it be determined whether the same good is final or intermediate?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. By its user and its role in production
Explanation: The classification of a good depends on its economic use, not on its physical identity or name. Milk bought by a household for drinking is a final good, whereas milk bought by a sweet-making firm is an intermediate input. The same product can therefore be final in one use and intermediate in another.
12 If GVA at factor cost (GVA₍FC₎) is ₹11,80,000, production taxes are ₹70,000, product taxes are ₹1,10,000, and product subsidies are ₹55,000, what is GVA at market prices (GVA₍MP₎)?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. ₹13,05,000
Explanation: To convert GVA at factor cost into GVA at market prices, add net taxes on production and products. Net indirect taxes here are production taxes plus product taxes minus product subsidies: ₹70,000 + ₹1,10,000 − ₹55,000 = ₹1,25,000. Thus, GVA₍MP₎ = ₹11,80,000 + ₹1,25,000 = ₹13,05,000. Therefore, option A is correct.
13 If closing stock is ₹1,15,000 more than opening stock and sales are ₹12,75,000, what is value of output?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. ₹13,90,000
Explanation: The change in stock is closing stock minus opening stock. Here, it is an increase of ₹1,15,000, which represents goods produced during the current year but not yet sold. Therefore, value of output equals sales plus increase in stock: ₹12,75,000 + ₹1,15,000 = ₹13,90,000. Hence, option B is correct.
14 Why is NFIA used to move from domestic income to national income?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Because domestic income is territory-based and national income is resident-based
Explanation: Domestic income measures factor income generated within a country’s domestic territory, regardless of whether the factors belong to residents or foreigners. National income measures factor income accruing to the country’s residents, including their income from abroad and excluding income sent abroad by foreign factors. Therefore, NFIA, calculated as factor income received from abroad minus factor income paid abroad, is added to domestic income to obtain national income.
15 If domestic income is ₹8,250 crore, factor income received from abroad ₹620 crore and factor income paid abroad ₹780 crore, what is national income?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. ₹8,090 करोड़
Explanation: National income is obtained by adding net factor income from abroad to domestic income. NFIA equals factor income received from abroad minus factor income paid abroad: ₹620 crore − ₹780 crore = −₹160 crore. Thus, national income = ₹8,250 crore − ₹160 crore = ₹8,090 crore. Since payments abroad exceed receipts, the adjustment is negative, so option C is correct.
16 Why is unpaid cooking service by a family member at home not included in the value added method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Because it is not a production service sold in the market
Explanation: In conventional national-income accounting, unpaid household services performed by family members for their own household are generally excluded from measured production. They do not have an observable market transaction or a reliable market price, and including them would make measurement inconsistent across households. If the same cooking service is provided by a paid domestic worker or a restaurant, its market value is included. Therefore, option A is correct.
17 Under the value added method, which of the following would be included in the domestic product of the current year?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Current-year service fee charged by a property broker on the sale of an old house
Explanation: The resale value of an old house is not current production because the house was produced and counted when it was originally constructed. However, the property broker performs a current-year brokerage service, and the fee is payment for that newly produced service, so it is included in domestic product. An old-age pension is a transfer payment, while share purchases are financial transactions; neither represents current production. Therefore, option B is correct.
18 How will a new server computer and internet data pack used in the same year be classified in the value added method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Server is fixed capital and data pack is intermediate service consumption
Explanation: A new server computer is a durable capital asset that provides productive services for more than one accounting period, so it is classified as fixed capital formation. An internet data pack is a service consumed during the current production period and does not normally provide a durable asset. It is therefore treated as intermediate consumption. Hence, the correct classification is given in option A.
19 What is the correct treatment of chemicals used in a school laboratory and teachers' salaries in the value added method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Chemicals are intermediate consumption and salaries are factor income
Explanation: Laboratory chemicals are goods consumed during the provision of the school’s educational service, so they are intermediate consumption. Teachers’ salaries are payments for the labour services used in producing education. They are therefore factor income and form part of the value added generated by the school. Since the two items have different economic roles, option A gives the correct treatment.
20 If the final good has a value of ₹8,40,000 and the value added at four preceding stages is ₹1,20,000, ₹1,75,000, ₹2,10,000 and ₹95,000, what is the value added by the final seller?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. ₹2,40,000
Explanation: Under the value-added method, the value of the final product equals the sum of value added at every stage of production. The value added before the final seller is ₹1,20,000 + ₹1,75,000 + ₹2,10,000 + ₹95,000 = ₹6,00,000. Therefore, the final seller’s value added is ₹8,40,000 − ₹6,00,000 = ₹2,40,000. This prevents double counting of intermediate goods.
21 What error in the value-added method can result from an incorrect adjustment for change in inventories?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Incorrect measurement of current-year output
Explanation: The value of current production is not always equal to the value of sales because some goods may remain unsold or may come from opening inventories. Current output is adjusted by adding the change in inventories, calculated as closing stock minus opening stock. If this adjustment is wrong, output and consequently gross value added are measured incorrectly. It does not automatically affect wages, NFIA, or taxes in the stated manner.
22 If GVA at market price is ₹18 lakh and depreciation of ₹2.4 lakh is deducted, with no tax adjustment made, what measure is obtained?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. NVA at market price
Explanation: Gross value added becomes net value added when consumption of fixed capital, or depreciation, is deducted. Thus, NVA at market price = ₹18 lakh − ₹2.4 lakh = ₹15.6 lakh. Since no adjustment for net indirect taxes is made, the valuation remains at market prices. Therefore, the resulting measure is NVA at market price, not NVA at factor cost or national income.
23 If only net indirect tax of ₹1.2 lakh is deducted from GVA at market price of ₹18 lakh and depreciation is not deducted, which measure is obtained?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. GVA at factor cost
Explanation: Subtracting net indirect tax changes the valuation from market price to factor cost: GVA at FC = ₹18 lakh − ₹1.2 lakh = ₹16.8 lakh. Because depreciation has not been deducted, the measure remains gross rather than net. Therefore, the correct result is GVA at factor cost. Depreciation would have to be deducted additionally to obtain NVA at factor cost.
24 A non-market government service has wages of ₹15 crore, intermediate consumption of ₹4 crore and consumption of fixed capital of ₹2 crore. What is its output value generally taken to be?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. ₹21 crore
Explanation: Non-market government services usually do not have an economically meaningful market price. Their output is therefore valued by the cost of production. The relevant components here are compensation of employees (₹15 crore), intermediate consumption (₹4 crore), and consumption of fixed capital (₹2 crore). Hence, output value = 15 + 4 + 2 = ₹21 crore. The calculation includes all stated production costs.
25 Why is a capital gain, such as an earning from a rise in land price, not included in the value-added method?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Because it is not value added from current production
Explanation: A capital gain results from a change in the market price of an existing asset, such as land. It does not represent a newly produced good or service during the accounting period. The value-added method measures value created through current production, so a mere increase in an asset’s price is excluded to avoid treating a price change as output.
