National Income and Related Aggregates
This is THE most important chapter in Macroeconomics — the chapter every board exam numerical is built on. There are 8 aggregates of National Income, and students often panic seeing all 8 formulas. Don’t worry — there is a simple secret: all 8 are created using just THREE SWITCHES applied to ONE base concept (GDP at Market Price). Master the three switches (Gross↔Net, Domestic↔National, Market Price↔Factor Cost) and you will never forget a formula again.

📌 The Big Picture
8 Aggregates, ONE Idea: Three Switches
Every one of the 8 National Income aggregates answers THREE yes/no questions about the SAME underlying value of production: (1) Gross or Net? (have we deducted depreciation?) (2) Domestic or National? (are we counting only what happened within the country, or including what residents earned abroad?) (3) Market Price or Factor Cost? (are we counting what buyers PAID, or what producers actually EARNED?) Three yes/no switches = 2 × 2 × 2 = 8 combinations = the 8 aggregates.
3.1 Introduction — The 8 Aggregates of National Income
National Income is not a single number — it has 8 different VARIANTS, each with a specific meaning, method of measurement and use. Here is the complete list, exactly as it appears in the CBSE syllabus:
| # | Aggregate | Short Form |
|---|---|---|
| 1 | Gross Domestic Product at Market Price | GDPMP |
| 2 | Gross Domestic Product at Factor Cost | GDPFC |
| 3 | Net Domestic Product at Market Price | NDPMP |
| 4 | Net Domestic Product at Factor Cost (also called Domestic Income) | NDPFC |
| 5 | Gross National Product at Market Price | GNPMP |
| 6 | Gross National Product at Factor Cost | GNPFC |
| 7 | Net National Product at Market Price | NNPMP |
| 8 | Net National Product at Factor Cost (also called National Income) | NNPFC |
Two Aggregates Have Special Nicknames — Remember These!
NDPFC is ALSO called “Domestic Income”
NNPFC is ALSO called “National Income” (THE most important aggregate — the “final answer” of this entire chapter)
NDPFC is ALSO called “Domestic Income”
NNPFC is ALSO called “National Income” (THE most important aggregate — the “final answer” of this entire chapter)
The Master Framework — Three Switches Explained
Master Mnemonic: “GDM” — Gross/Net, Domestic/National, Market Price/Factor Cost
Every aggregate name reads left to right using these THREE switches, in order: [Gross or Net] + [Domestic or National] + Product at + [Market Price or Factor Cost]
Every aggregate name reads left to right using these THREE switches, in order: [Gross or Net] + [Domestic or National] + Product at + [Market Price or Factor Cost]
1
Switch 1: GROSS vs NET (adjusted by DEPRECIATION)
GROSS = value of production BEFORE deducting depreciation (wear and tear of capital).
NET = value of production AFTER deducting depreciation.
Formula: Net = Gross — Depreciation
Recall Chapter 2: Depreciation is the normal wear and tear of capital goods used in production.
2
Switch 2: DOMESTIC vs NATIONAL (adjusted by NFIA)
DOMESTIC = value of production WITHIN the domestic territory only (by residents AND non-residents operating there).
NATIONAL = value of production/income belonging to NORMAL RESIDENTS (wherever earned — domestically or abroad).
Formula: National = Domestic + NFIA
Recall Chapter 2: NFIA = Net Factor Income from Abroad = income residents earn abroad minus income non-residents earn domestically.
3
Switch 3: MARKET PRICE vs FACTOR COST (adjusted by NIT)
MARKET PRICE = the price the BUYER actually pays (includes indirect taxes, net of subsidies).
FACTOR COST = the amount the PRODUCER actually receives/earns (excludes government tax/subsidy intervention).
Formula: Factor Cost = Market Price — NIT
Recall Chapter 2: NIT (Net Indirect Taxes) = Indirect Taxes — Subsidies.
📌 How to Build ANY of the 8 Formulas Instantly
Start from the BASE CONCEPT: GDPMP (Gross Domestic Product at Market Price) — this is the value of ALL final goods and services produced WITHIN the domestic territory during a year, valued at the price BUYERS pay.
From GDPMP, apply the THREE adjustments to reach any of the other 7 aggregates:
• Want to remove depreciation? Subtract Depreciation (Gross → Net)
• Want to include foreign earnings? Add NFIA (Domestic → National)
• Want producer earnings, not buyer price? Subtract NIT (Market Price → Factor Cost)
All 8 Formulas — Complete Reference
1
GDPMP (Base Concept)
Sum of value added by all producing units WITHIN domestic territory, valued at market price, BEFORE deducting depreciation. This is where every calculation STARTS.
2
GDPFC = GDPMP — NIT
Remove the government tax/subsidy effect to see what producers actually earned, still within domestic territory, still before depreciation.
3
NDPMP = GDPMP — Depreciation
Remove the wear-and-tear of capital to see the TRUE net addition, still valued at market price, still domestic.
4
NDPFC = NDPMP — NIT = GDPFC — Depreciation
(“Domestic Income”)
BOTH adjustments applied: net of depreciation AND at factor cost, but still domestic only (no foreign income included).
5
GNPMP = GDPMP + NFIA
Add income earned by residents abroad (minus what non-residents earned domestically) to shift from domestic to national, still gross, still at market price.
6
GNPFC = GNPMP — NIT = GDPFC + NFIA
National + Factor Cost, but still gross (before depreciation).
7
NNPMP = GNPMP — Depreciation = NDPMP + NFIA
National + Net, but still at market price (includes NIT effect).
8
NNPFC = GNPFC — Depreciation = NDPFC + NFIA
(“National Income” — THE FINAL ANSWER)
ALL THREE adjustments applied: Net (no depreciation) + National (includes foreign earnings) + Factor Cost (producer earnings only). This is what economists mean when they simply say “National Income” without qualification.
The Master Formula — National Income from GDPMP in ONE line:
NNPFC (National Income) = GDPMP — Depreciation — NIT + NFIA
Apply all three switches simultaneously to the base concept and you land on National Income directly.
NNPFC (National Income) = GDPMP — Depreciation — NIT + NFIA
Apply all three switches simultaneously to the base concept and you land on National Income directly.

3.2 Basic Aggregates of National Income — Why We Use MONEY, Not Quantity
📌 The Core Problem
You Cannot ADD Different Physical Units
In an economy, different producing units produce COMPLETELY DIFFERENT types of goods and services during the year — wheat is measured in tonnes, mobile phones are counted in units, machines are counted in units, haircuts are counted as services with no physical unit at all.
The problem: You CANNOT simply ADD 5,000 tonnes of wheat + 10,000 mobile phones + 7,000 machines. These are different PHYSICAL units that cannot be combined meaningfully — it would be like adding 5 apples + 3 kilometres + 2 hours. The units don’t match.
The Solution: Convert Everything to a COMMON UNIT — MONEY (Rupees)
Since every good and service has a PRICE in the market, we can convert ALL production into its MONETARY VALUE (Rs) and then these values CAN be added together, because Rupees IS a common, comparable unit.
Since every good and service has a PRICE in the market, we can convert ALL production into its MONETARY VALUE (Rs) and then these values CAN be added together, because Rupees IS a common, comparable unit.
1
Why Money Works as a Common Denominator
5,000 tonnes of wheat at Rs 25,000/tonne = Rs 12.5 crore. 10,000 mobile phones at Rs 15,000 each = Rs 15 crore. 7,000 machines at Rs 5 lakh each = Rs 350 crore. NOW we can add: Rs 12.5 crore + Rs 15 crore + Rs 350 crore = Rs 377.5 crore total value. This is only possible because we converted physical quantities into a COMMON monetary unit.
2
National Income Aggregates Are Always in Money Terms
This is why every one of the 8 aggregates (GDP, GNP, NDP, NNP at Market Price or Factor Cost) is expressed in RUPEES (or another currency) — NEVER in physical units like tonnes, litres or number of units. “India’s GDP = Rs 295 lakh crore” makes sense; “India’s GDP = 500 million tonnes” does not.
⚡ Quick Recall — Chapter 3: National Income and Related Aggregates
8 aggregates: GDP MP, GDP FC, NDP MP, NDP FC (Domestic Income), GNP MP, GNP FC, NNP MP, NNP FC (National Income). NNP FC is THE final “National Income” figure.
Three switches build all 8: Gross↔Net (adjusted by Depreciation), Domestic↔National (adjusted by NFIA), Market Price↔Factor Cost (adjusted by NIT). 2×2×2 = 8 combinations.
Base concept: GDP MP. Master formula: National Income (NNP FC) = GDP MP — Depreciation — NIT + NFIA.
Gross to Net: subtract Depreciation. Domestic to National: add NFIA. Market Price to Factor Cost: subtract NIT.
NDP FC = Domestic Income. NNP FC = National Income. These two special names are frequently tested.
National Income aggregates are always expressed in MONEY (Rupees) terms, never in physical quantities, because different goods (wheat, phones, machines) have different physical units that cannot be added directly — only their monetary values can be summed.

30 MCQs — National Income and Related Aggregates
The 8 aggregates, three-switch conversions and numerical calculations. Q25–Q30 are CUET-level. Heavy numerical focus since this is the formula chapter.
📚 Questions 1 to 30
1
How many aggregates of National Income are there according to the CBSE syllabus, and what is the BASE concept from which all others can be derived?
A6 aggregates; base concept is National Income (NNP FC)
B8 aggregates; base concept is GDP at Market Price (GDP MP), from which the other 7 are derived using three adjustments (Depreciation, NIT, NFIA)
C10 aggregates; base concept is GNP at Factor Cost
D4 aggregates; base concept is Domestic Income
Answer: B — 8 aggregates; GDP MP is the base. The 8 aggregates are: GDP MP, GDP FC, NDP MP, NDP FC (Domestic Income), GNP MP, GNP FC, NNP MP, NNP FC (National Income). GDP MP is the STARTING/BASE concept because it is the simplest, most directly observable value — the total value of production within domestic territory, valued at market prices, before any deductions. All other 7 aggregates are derived from GDP MP by applying combinations of three adjustments: subtracting Depreciation, subtracting NIT, and adding NFIA.
2
Which adjustment converts GROSS aggregates into NET aggregates?
AAdding Net Factor Income from Abroad (NFIA)
BAdding Net Indirect Taxes (NIT)
CSubtracting Depreciation — Gross aggregates INCLUDE depreciation (wear and tear of capital); Net aggregates EXCLUDE it, giving the TRUE addition to the economy productive value
DMultiplying by the inflation rate
Answer: C — Subtract Depreciation to go from Gross to Net. Formula: NET = GROSS — DEPRECIATION. This is the “Gross vs Net” switch, one of the THREE switches that build all 8 aggregates. GROSS aggregates (GDP MP, GDP FC, GNP MP, GNP FC) count the TOTAL value of production WITHOUT deducting the wear and tear of capital used up in that production. NET aggregates (NDP MP, NDP FC, NNP MP, NNP FC) deduct depreciation to show the TRUE net value added, after accounting for capital consumed in the production process.
3
Which adjustment converts DOMESTIC aggregates into NATIONAL aggregates?
ASubtracting Depreciation
BAdding Net Factor Income from Abroad (NFIA) — Domestic aggregates count only production WITHIN the territory; National aggregates ADD the income residents earn abroad (minus what non-residents earn domestically) to reflect income belonging to RESIDENTS wherever earned
CSubtracting Net Indirect Taxes (NIT)
DDividing by the population of the country
Answer: B — Add NFIA to go from Domestic to National. Formula: NATIONAL = DOMESTIC + NFIA. This is the “Domestic vs National” switch. DOMESTIC aggregates (GDP MP, GDP FC, NDP MP, NDP FC) measure value PRODUCED WITHIN the country territory, regardless of who produced it (residents or non-residents). NATIONAL aggregates (GNP MP, GNP FC, NNP MP, NNP FC) measure income BELONGING TO normal residents, WHEREVER in the world it was earned — requiring the NFIA adjustment to account for cross-border factor income flows.
4
Which adjustment converts MARKET PRICE aggregates into FACTOR COST aggregates?
AAdding Depreciation
BAdding NFIA
CSubtracting Net Indirect Taxes (NIT) — Market Price aggregates reflect what BUYERS pay (including government indirect taxes, net of subsidies); Factor Cost aggregates reflect what PRODUCERS actually earn, excluding the government tax/subsidy component
DMultiplying by the exchange rate
Answer: C — Subtract NIT to go from Market Price to Factor Cost. Formula: FACTOR COST = MARKET PRICE — NIT (where NIT = Indirect Taxes — Subsidies). This is the “Market Price vs Factor Cost” switch. MARKET PRICE aggregates (GDP MP, NDP MP, GNP MP, NNP MP) include the effect of government indirect taxes and subsidies in the price. FACTOR COST aggregates (GDP FC, NDP FC, GNP FC, NNP FC) strip out this government intervention to show only what factors of production (land, labour, capital, entrepreneurship) actually earned.
5
Which of the 8 aggregates is ALSO known as “National Income” when used without any qualification?
AGDP MP (Gross Domestic Product at Market Price)
BNDP FC (Net Domestic Product at Factor Cost)
CNNP FC (Net National Product at Factor Cost) — this aggregate has ALL THREE adjustments applied (Net, National, Factor Cost), making it the “purest” measure of income actually earned by a country residents; when economists say “National Income” alone, they mean this
DGNP MP (Gross National Product at Market Price)
Answer: C — NNP FC = National Income. NNP FC has undergone ALL THREE adjustments from the base GDP MP: it is NET (depreciation removed), NATIONAL (NFIA added, reflects resident income wherever earned) and at FACTOR COST (NIT removed, shows actual producer earnings, not buyer-paid prices). Because it represents the most complete and accurate measure of the TRUE income earned by a country’s normal residents, economists use the term “National Income” specifically to refer to NNP FC. Similarly, NDP FC has the special name “Domestic Income.”
6
📋 CASE: Given: GDPMP = Rs 500 crore, Depreciation = Rs 50 crore. Calculate NDPMP:
ANDP MP = Rs 550 crore (Rs 500 + Rs 50)
BNDP MP = GDP MP — Depreciation = Rs 500 crore — Rs 50 crore = Rs 450 crore
CNDP MP = Rs 500 crore (depreciation does not affect this aggregate)
DNDP MP = Rs 50 crore (depreciation IS the NDP MP)
Answer: B — NDP MP = Rs 450 crore. NDPMP = GDPMP — Depreciation. Applying the “Gross to Net” switch: Rs 500 crore — Rs 50 crore = Rs 450 crore. Both figures remain at MARKET PRICE (no NIT adjustment applied yet) and DOMESTIC (no NFIA adjustment applied yet) — only the Gross→Net switch (depreciation deduction) has been used here.
7
📋 CASE: Given: GDPMP = Rs 800 crore, Net Indirect Taxes (NIT) = Rs 60 crore. Calculate GDPFC:
AGDP FC = Rs 860 crore (Rs 800 + Rs 60)
BGDP FC = GDP MP — NIT = Rs 800 crore — Rs 60 crore = Rs 740 crore
CGDP FC = Rs 800 crore (NIT does not affect GDP)
DGDP FC = Rs 60 crore
Answer: B — GDP FC = Rs 740 crore. GDPFC = GDPMP — NIT. Applying the “Market Price to Factor Cost” switch: Rs 800 crore — Rs 60 crore = Rs 740 crore. This removes the government indirect tax/subsidy component, showing what producers actually earned from their factors of production, still keeping the figure GROSS (no depreciation deducted) and DOMESTIC (no NFIA added).
8
📋 CASE: Given: GDPMP = Rs 600 crore, NFIA = Rs 15 crore (positive). Calculate GNPMP:
AGNP MP = Rs 585 crore (Rs 600 — Rs 15)
BGNP MP = GDP MP + NFIA = Rs 600 crore + Rs 15 crore = Rs 615 crore
CGNP MP = Rs 600 crore (NFIA has no effect on National aggregates)
DGNP MP = Rs 15 crore
Answer: B — GNP MP = Rs 615 crore. GNPMP = GDPMP + NFIA. Applying the “Domestic to National” switch: Rs 600 crore + Rs 15 crore = Rs 615 crore. Since NFIA is POSITIVE (residents earned more abroad than non-residents earned domestically), the NATIONAL aggregate (GNP) is LARGER than the DOMESTIC aggregate (GDP). This remains GROSS (no depreciation deducted) and at MARKET PRICE (no NIT adjustment applied).
9
📋 CASE: Given the following data for an economy: GDPMP = Rs 1,000 crore, Depreciation = Rs 100 crore, NIT = Rs 80 crore, NFIA = — Rs 20 crore (negative). Calculate National Income (NNPFC):
ANational Income = Rs 1,200 crore (adding all values)
BNational Income = GDP MP — Depreciation — NIT + NFIA = Rs 1,000 — Rs 100 — Rs 80 + (−Rs 20) = Rs 800 crore
CNational Income = Rs 1,000 crore (aggregates are always equal to GDP MP)
DNational Income = Rs 820 crore (forgetting to apply the negative NFIA correctly)
Answer: B — National Income = Rs 800 crore. Using the MASTER FORMULA: NNPFC (National Income) = GDPMP — Depreciation — NIT + NFIA = Rs 1,000 — Rs 100 — Rs 80 + (−Rs 20) = Rs 1,000 — Rs 100 — Rs 80 — Rs 20 = Rs 800 crore. Since NFIA is NEGATIVE, adding a negative number is the SAME as subtracting — so all four adjustments effectively subtract from GDP MP in this case, since Depreciation, NIT are both subtracted and NFIA being negative also reduces the total.
10
Which of the following correctly shows the relationship between GDPFC and NDPFC (Domestic Income)?
ANDP FC = GDP FC + Depreciation
BNDP FC = GDP FC — Depreciation — applying the Gross to Net switch (subtracting depreciation) while BOTH remain at Factor Cost and Domestic level
CNDP FC = GDP FC + NFIA
DNDP FC and GDP FC are always identical
Answer: B — NDP FC = GDP FC — Depreciation. Both GDPFC and NDPFC are at FACTOR COST (both had NIT subtracted already) and both are DOMESTIC (no NFIA applied) — the ONLY difference between them is the Gross vs Net switch. GDPFC is GROSS (before depreciation); NDPFC is NET (after depreciation). So: NDPFC = GDPFC — Depreciation. This confirms that you can reach NDPFC (Domestic Income) via TWO different paths from GDPMP: either (GDP MP — NIT — Depreciation) or (GDP MP — Depreciation — NIT) — the order does not matter, the result is the same.
11
📋 CASE: An economy has GNPFC = Rs 900 crore and Depreciation = Rs 70 crore. Calculate NNPFC (National Income):
ANNP FC = Rs 970 crore (Rs 900 + Rs 70)
BNNP FC = GNP FC — Depreciation = Rs 900 crore — Rs 70 crore = Rs 830 crore
CNNP FC = Rs 900 crore (depreciation does not apply here)
DNNP FC cannot be calculated without knowing NFIA
Answer: B — NNP FC (National Income) = Rs 830 crore. Both GNPFC and NNPFC are already at FACTOR COST and NATIONAL level (NIT and NFIA adjustments already applied to reach GNPFC from the base). The ONLY remaining switch is Gross to Net: NNPFC = GNPFC — Depreciation = Rs 900 — Rs 70 = Rs 830 crore. Note that Option D is a trap — since we already have GNPFC (which already includes the NFIA adjustment baked in), we do NOT need to separately apply NFIA again to reach NNPFC.
12
📋 CASE: Given: NDPMP = Rs 700 crore, NFIA = Rs 25 crore. Calculate NNPMP:
ANNP MP = Rs 675 crore (Rs 700 — Rs 25)
BNNP MP = NDP MP + NFIA = Rs 700 crore + Rs 25 crore = Rs 725 crore
CNNP MP = Rs 700 crore (NFIA is only relevant for Factor Cost aggregates)
DNNP MP cannot be derived from NDP MP directly
Answer: B — NNP MP = Rs 725 crore. Both NDPMP and NNPMP are already NET (depreciation already deducted) and at MARKET PRICE (no NIT adjustment applied to either). The ONLY remaining switch is Domestic to National: NNPMP = NDPMP + NFIA = Rs 700 + Rs 25 = Rs 725 crore. This confirms that the NFIA adjustment works identically whether applied to Gross or Net, Market Price or Factor Cost aggregates — it always represents the same “Domestic to National” switch.
13
📋 CASE: An economy has the following: GDPMP = Rs 2,000 crore, Depreciation = Rs 150 crore, NIT = Rs 120 crore, NFIA = Rs 30 crore. Calculate Domestic Income (NDPFC):
ANDP FC = Rs 2,300 crore (adding all figures)
BNDP FC = GDP MP — Depreciation — NIT = Rs 2,000 — Rs 150 — Rs 120 = Rs 1,730 crore (NFIA is NOT used since Domestic Income stays at the DOMESTIC level, not National)
CNDP FC = Rs 1,760 crore (including NFIA by mistake)
DNDP FC = Rs 2,000 crore (no adjustments applied)
Answer: B — NDP FC (Domestic Income) = Rs 1,730 crore. IMPORTANT TRAP: NDPFC (Domestic Income) remains at the DOMESTIC level — NFIA should NOT be applied here, only Depreciation and NIT are relevant. NDPFC = GDPMP — Depreciation — NIT = Rs 2,000 — Rs 150 — Rs 120 = Rs 1,730 crore. The NFIA figure (Rs 30 crore) given in this problem is EXTRA/IRRELEVANT information for calculating NDPFC specifically — it would only be needed if the question asked for a NATIONAL aggregate like GNP or NNP.
14
If a country’s NFIA is NEGATIVE, which relationship correctly describes GNPMP compared to GDPMP?
AGNP MP will always be GREATER than GDP MP
BGNP MP will be LESS than GDP MP, since GNP MP = GDP MP + NFIA, and adding a negative number REDUCES the total
CGNP MP will always EQUAL GDP MP regardless of NFIA sign
DThe relationship cannot be determined without knowing Depreciation
Answer: B — GNP MP will be LESS than GDP MP when NFIA is negative. Formula: GNPMP = GDPMP + NFIA. If NFIA is NEGATIVE (foreigners earn more within the domestic economy than residents earn abroad — typical of countries with heavy foreign investment), then adding a negative number to GDPMP REDUCES the total, making GNPMP SMALLER than GDPMP. Depreciation is irrelevant to this specific comparison since both GDPMP and GNPMP are GROSS aggregates (neither has depreciation deducted).
15
📋 CASE: Given: NNPMP = Rs 850 crore, NIT = Rs 65 crore. Calculate NNPFC (National Income):
ANNP FC = Rs 915 crore (Rs 850 + Rs 65)
BNNP FC = NNP MP — NIT = Rs 850 crore — Rs 65 crore = Rs 785 crore
CNNP FC = Rs 850 crore (NIT does not apply to National aggregates)
DCannot be calculated without Depreciation figure
Answer: B — NNP FC (National Income) = Rs 785 crore. Both NNPMP and NNPFC are already NET (depreciation deducted) and NATIONAL (NFIA already applied) — the ONLY remaining switch is Market Price to Factor Cost: NNPFC = NNPMP — NIT = Rs 850 — Rs 65 = Rs 785 crore. This shows the final step in reaching National Income from a partially-adjusted starting point — you only need to apply whichever switches have NOT yet been used.
16
Why can we NOT simply add the physical quantities of wheat, mobile phones and machines produced in an economy to arrive at National Income?
ABecause the government prohibits adding quantities of different goods
BBecause these goods are measured in DIFFERENT PHYSICAL UNITS (tonnes, number of units, etc.) that cannot be meaningfully combined; only their MONETARY VALUES (a common unit) can be added together
CBecause wheat, phones and machines are not considered part of GDP
DBecause only exported goods count toward National Income
Answer: B — Different physical units cannot be combined; only monetary VALUE can be added. Wheat is measured in TONNES, mobile phones are counted in UNITS, machines are counted in UNITS — these are fundamentally different, incompatible physical measures (like trying to add kilometres + kilograms + hours). The SOLUTION is to convert each good/service into its MONETARY VALUE using its market price (quantity × price = value in Rupees). Since Rupees is a COMMON unit applicable to ALL goods and services, these monetary values CAN be meaningfully added together to arrive at total National Income figures.
17
📋 CASE: An economy produces 5,000 tonnes of wheat (Rs 20,000/tonne) and 8,000 laptops (Rs 40,000 each) in a year. What is the TOTAL monetary value of this production?
A13,000 units (adding quantities directly: 5,000 + 8,000)
BRs 42 crore total (Wheat: 5,000 × Rs 20,000 = Rs 10 crore; Laptops: 8,000 × Rs 40,000 = Rs 32 crore; Total = Rs 10 crore + Rs 32 crore = Rs 42 crore)
CRs 60,000 (adding the per-unit prices: Rs 20,000 + Rs 40,000)
DCannot be calculated since wheat and laptops are fundamentally different goods
Answer: B — Total value = Rs 42 crore. This demonstrates the “common unit” principle in action: WHEAT: 5,000 tonnes × Rs 20,000/tonne = Rs 10,00,00,000 = Rs 10 crore. LAPTOPS: 8,000 units × Rs 40,000/unit = Rs 32,00,00,000 = Rs 32 crore. Since BOTH values are now expressed in the SAME unit (Rupees), we CAN add them: Rs 10 crore + Rs 32 crore = Rs 42 crore TOTAL value of production. This is EXACTLY how national income aggregates are built — converting all diverse production into money value first, THEN summing.
18
Which of the following is the CORRECT relationship between GNPFC and GDPFC?
AGNP FC = GDP FC — Depreciation
BGNP FC = GDP FC + NFIA — both are already at Factor Cost (NIT already subtracted); the only remaining switch to go from Domestic (GDP) to National (GNP) is adding NFIA
CGNP FC = GDP FC × NFIA
DGNP FC and GDP FC are always identical, regardless of NFIA
Answer: B — GNP FC = GDP FC + NFIA. Both GDPFC and GNPFC are at FACTOR COST (both have had NIT subtracted already) and both are GROSS (neither has depreciation deducted). The ONLY remaining switch between them is Domestic to National: GNPFC = GDPFC + NFIA. This is another example of how, once you understand the three-switch framework, you can identify the SPECIFIC missing switch between ANY two of the 8 aggregates just by comparing their names.
19
📋 CASE: A student calculates National Income (NNPFC) using this formula: NNPFC = GDPMP + Depreciation + NIT — NFIA. Is this formula CORRECT?
AYes, this is the correct formula
BNo — the CORRECT formula is NNP FC = GDP MP — Depreciation — NIT + NFIA; the student has REVERSED all three signs (should SUBTRACT Depreciation and NIT, and ADD NFIA, not the opposite)
CYes, but only when NFIA is negative
DBoth formulas give the same answer mathematically
Answer: B — The student has reversed all three signs; this is incorrect. The CORRECT master formula is: NNPFC (National Income) = GDPMP — DEPRECIATION — NIT + NFIA. Remember the switches: Gross→Net means SUBTRACT Depreciation (not add). Market Price→Factor Cost means SUBTRACT NIT (not add). Domestic→National means ADD NFIA (not subtract). The student formula has all three operations BACKWARDS, which would give a completely wrong (usually much higher) answer. This is one of the MOST COMMON errors students make — always double-check the direction of each adjustment.
20
📋 CASE: Given: GNPMP = Rs 1,500 crore, Depreciation = Rs 100 crore, NIT = Rs 90 crore. Calculate National Income (NNPFC):
ANational Income = Rs 1,690 crore (adding both figures)
BNational Income = GNP MP — Depreciation — NIT = Rs 1,500 — Rs 100 — Rs 90 = Rs 1,310 crore
CNational Income = Rs 1,500 crore (no further adjustment needed since GNP is already National)
DNational Income = Rs 1,410 crore (only subtracting Depreciation)
Answer: B — National Income (NNP FC) = Rs 1,310 crore. Since we START from GNPMP (which is already NATIONAL — the NFIA switch has already been applied to reach it from GDPMP), we only need TWO remaining switches to reach NNPFC: subtract Depreciation (Gross→Net) AND subtract NIT (Market Price→Factor Cost). NNPFC = GNPMP — Depreciation — NIT = Rs 1,500 — Rs 100 — Rs 90 = Rs 1,310 crore. Notice we do NOT apply NFIA again since it is already embedded within GNPMP.
21
In the name “Gross National Product at Factor Cost,” which THREE pieces of information does the name convey?
AThe currency, the year and the country name
B“Gross” = before deducting Depreciation; “National” = includes NFIA (income of residents, wherever earned); “at Factor Cost” = NIT has been deducted (producer earnings, not buyer prices)
CThe tax rate, the inflation rate and the exchange rate
DThe population, the growth rate and the price level
Answer: B — Gross/National/Factor Cost each convey one of the three switches. Every aggregate name is built from the THREE switches read in order: [Gross or Net] tells you whether Depreciation has been deducted. [Domestic or National] tells you whether NFIA has been applied. [at Market Price or at Factor Cost] tells you whether NIT has been deducted. “Gross National Product at Factor Cost” = GROSS (depreciation NOT deducted) + NATIONAL (NFIA IS included) + at FACTOR COST (NIT IS deducted). Understanding this naming logic lets you instantly know what adjustments are ALREADY applied and which ones remain.
22
📋 CASE: A country reports GDPMP = Rs 300 lakh crore for the year. A student says “this means every citizen received exactly this much money.” Is this correct?
AYes, GDP MP directly represents money distributed to citizens
BNo — GDP MP is the TOTAL MONETARY VALUE of all final goods and services produced within the domestic territory during the year; it is a measure of PRODUCTION VALUE, not a literal distribution of money to individuals
CYes, but only for the National aggregates, not GDP
DNo, GDP MP measures only exports, not total production
Answer: B — GDP MP is a production value measure, not literal money distribution. GDPMP represents the TOTAL MONETARY VALUE of goods and services produced — it is calculated by converting all diverse physical production (measured in different units) into a COMMON monetary value using market prices, then summing. It is NOT a literal pool of cash distributed among citizens. The monetary expression is simply a NECESSARY TECHNIQUE to make different types of production comparable and addable — it reflects the VALUE created, which eventually flows through the economy as income, but is not itself a direct cash handout.

Which of the following is Domestic Income also known as?
AGDP MP
BNDP FC (Net Domestic Product at Factor Cost) — this is the special name given to this aggregate because it represents the true income earned by factors of production WITHIN the domestic territory, after removing depreciation and government tax/subsidy effects
CGNP FC
DNNP MP
Answer: B — NDP FC is Domestic Income. NDPFC (Net Domestic Product at Factor Cost) has TWO of the three adjustments applied: NET (depreciation removed) and FACTOR COST (NIT removed) — but it remains DOMESTIC (NFIA is NOT applied). This makes it the most accurate measure of income earned by factors of production PHYSICALLY WITHIN the country boundaries, which is why it earns the special name “Domestic Income.” Compare with NNPFC which additionally includes NFIA, earning the name “National Income.”

📋 CASE: Given: NDPFC (Domestic Income) = Rs 1,200 crore, NFIA = Rs 40 crore. Calculate NNPFC (National Income):
ANational Income = Rs 1,160 crore (Rs 1,200 — Rs 40)
BNational Income = NDP FC + NFIA = Rs 1,200 crore + Rs 40 crore = Rs 1,240 crore
CNational Income = Rs 1,200 crore (Domestic Income and National Income are always equal)
DCannot be calculated without Depreciation and NIT figures
Answer: B — National Income = Rs 1,240 crore. Both NDPFC and NNPFC are already NET (depreciation deducted) and at FACTOR COST (NIT deducted). The ONLY remaining switch is Domestic to National: NNPFC = NDPFC + NFIA = Rs 1,200 + Rs 40 = Rs 1,240 crore. This demonstrates the direct relationship between the two “special name” aggregates: National Income = Domestic Income + NFIA. This is a frequently tested direct-conversion question.

[CUET Level] Assertion (A): GDP MP is always greater than or equal to GDP FC when Net Indirect Taxes are positive.
Reason (R): GDP FC = GDP MP — NIT, and subtracting a positive value from GDP MP results in a smaller or equal number.
Reason (R): GDP FC = GDP MP — NIT, and subtracting a positive value from GDP MP results in a smaller or equal number.
ABoth A and R are true, and R correctly explains A — if NIT is positive, subtracting it from GDP MP mathematically produces a value that is less than or equal to GDP MP, confirming GDP MP ≥ GDP FC
BBoth A and R are true, but R does not explain A
CA is true but R is false
DBoth A and R are false
Answer: A — Both true, R correctly explains A. A is TRUE: When NIT (Indirect Taxes minus Subsidies) is positive, GDPMP ≥ GDPFC. R is TRUE and EXPLAINS A: The formula GDPFC = GDPMP — NIT is basic subtraction. If NIT > 0 (positive), then subtracting a positive number from GDPMP necessarily gives a result LESS than or equal to GDPMP (equal only if NIT = 0). This mathematical logic directly explains why GDPMP is greater than or equal to GDPFC whenever NIT is positive — which is the TYPICAL case in most economies (indirect taxes usually exceed subsidies).

[CUET Level] Assertion (A): It is impossible to calculate National Income (NNP FC) if you are only given GDP MP, Depreciation and NIT, without knowing NFIA separately.
Reason (R): NFIA is one of the three essential adjustments (along with Depreciation and NIT) required to convert GDP MP into National Income.
Reason (R): NFIA is one of the three essential adjustments (along with Depreciation and NIT) required to convert GDP MP into National Income.
ABoth A and R are true, and R correctly explains A — since NNP FC = GDP MP — Depreciation — NIT + NFIA, all four values (including NFIA) are needed; without NFIA, the National Income figure cannot be completed, only the Domestic Income (NDP FC) can be calculated
BBoth A and R are true, but R does not correctly explain A
CA is false; NFIA is not needed to calculate National Income
DBoth A and R are false
Answer: A — Both true, R correctly explains A. A is TRUE: without NFIA, you can only reach NDPFC (Domestic Income) using GDPMP, Depreciation and NIT — but you CANNOT reach NNPFC (National Income) because that requires the additional Domestic→National conversion via NFIA. R is TRUE and CORRECTLY EXPLAINS A: the master formula NNPFC = GDPMP — Depreciation — NIT + NFIA explicitly requires all THREE adjustment values. Missing any one of the three (Depreciation, NIT, or NFIA) means you cannot compute the FULL National Income figure — you can only compute a PARTIALLY adjusted aggregate.

[CUET Level — Incorrect Pair] Which of the following formula pairs is INCORRECTLY matched?
ANDP MP = GDP MP — Depreciation
BGNP FC = GDP FC + NFIA
CNNP FC = GNP MP + Depreciation — INCORRECT: the correct formula is NNP FC = GNP MP — Depreciation — NIT (Gross to Net requires SUBTRACTING depreciation, not adding it)
DGDP FC = GDP MP — NIT
Answer: C is incorrectly matched. The CORRECT relationship is: NNPFC = GNPMP — Depreciation — NIT (both remaining switches applied with SUBTRACTION, since Gross→Net always means subtract Depreciation, and Market Price→Factor Cost always means subtract NIT). Option C states “+ Depreciation” which is backwards — ADDING depreciation would mean going from Net BACK to Gross, the opposite direction. Options A, B and D are all correctly stated: NDPMP = GDPMP — Depreciation (Gross to Net); GNPFC = GDPFC + NFIA (Domestic to National); GDPFC = GDPMP — NIT (Market Price to Factor Cost).

[CUET Level — Case] 📋 An economy reports: GDPMP = Rs 3,000 crore, Depreciation = Rs 200 crore, NIT = Rs 150 crore, NFIA = −Rs 50 crore (negative). Calculate ALL FOUR of: GDPFC, NDPMP, NDPFC and NNPFC:
AGDP FC = Rs 2,850; NDP MP = Rs 2,800; NDP FC = Rs 2,650; NNP FC = Rs 2,600
BGDP FC = GDP MP — NIT = Rs 2,850 crore. NDP MP = GDP MP — Depreciation = Rs 2,800 crore. NDP FC = GDP MP — Depreciation — NIT = Rs 2,650 crore. NNP FC = NDP FC + NFIA = Rs 2,650 + (−Rs 50) = Rs 2,600 crore
CAll four aggregates equal Rs 3,000 crore since NFIA is negative and cancels adjustments
DGDP FC = Rs 3,150; NDP MP = Rs 3,200; NDP FC = Rs 3,350; NNP FC = Rs 3,400
Answer: B — GDP FC=2,850; NDP MP=2,800; NDP FC=2,650; NNP FC=2,600 (all in crore). Step-by-step: GDPFC = 3,000 — 150 (NIT) = Rs 2,850 crore. NDPMP = 3,000 — 200 (Depreciation) = Rs 2,800 crore. NDPFC = 3,000 — 200 — 150 = Rs 2,650 crore (both Depreciation and NIT subtracted, still Domestic). NNPFC (National Income) = NDPFC + NFIA = 2,650 + (−50) = Rs 2,600 crore (since NFIA is negative, this REDUCES the Domestic Income figure to reach National Income — meaning foreigners earned more within India than Indians earned abroad in this scenario).

[CUET Level — Case] 📋 Which of these THREE relationships correctly and simultaneously hold TRUE for any economy (mark the one INCORRECT statement)?
AGDP MP ≥ GDP FC whenever NIT is positive
BGDP MP ≥ NDP MP whenever Depreciation is positive (which it almost always is)
CGNP MP is ALWAYS greater than GDP MP regardless of the sign of NFIA — INCORRECT: GNP MP is greater than GDP MP ONLY when NFIA is positive; if NFIA is negative, GNP MP will be LESS than GDP MP
DNNP FC (National Income) is generally the SMALLEST of the 8 aggregates when both Depreciation and NIT are positive and NFIA is negative or small
Answer: C is the INCORRECT statement. Statement C claims GNPMP is ALWAYS greater than GDPMP — this is FALSE. GNPMP = GDPMP + NFIA. If NFIA is POSITIVE, GNPMP > GDPMP (true). But if NFIA is NEGATIVE, GNPMP < GDPMP (the OPPOSITE). The relationship depends entirely on the SIGN of NFIA, which varies by country (India typically has positive NFIA due to NRI remittances/earnings, while countries with heavy foreign investment often have negative NFIA). Statements A, B and D are all correctly and generally true given standard conditions (positive NIT, positive Depreciation).

[CUET Level — Comprehensive] 📋 A teacher asks: “If I give you GDPMP, Depreciation, NIT and NFIA, can you calculate ALL 8 aggregates?” Evaluate this claim:
ANo, additional data like population and inflation rate is also required
BYes — TRUE. With GDP MP as the base and the three adjustment values (Depreciation, NIT, NFIA), all 8 combinations of the three switches (Gross/Net × Domestic/National × Market Price/Factor Cost = 2×2×2 = 8) can be systematically derived by applying the relevant subset of adjustments
CNo, only 4 aggregates can be calculated from this data; the other 4 require separate data collection
DNo, this data can only give you the National aggregates, not the Domestic ones
Answer: B — TRUE, all 8 can be calculated from these 4 pieces of data. This confirms the ENTIRE logic of the chapter: with GDPMP (base) + Depreciation + NIT + NFIA (the three adjustment values), you can systematically construct ALL 8 aggregates by applying whichever COMBINATION of the three switches is needed: GDPMP (no adjustments) → GDPFC (−NIT) → NDPMP (−Dep) → NDPFC (−Dep−NIT) → GNPMP (+NFIA) → GNPFC (+NFIA−NIT) → NNPMP (+NFIA−Dep) → NNPFC (+NFIA−Dep−NIT). This is precisely why mastering the THREE-SWITCH framework (rather than memorising 8 separate formulas) makes this chapter dramatically easier.
