Question 1
Question
Assume a hypothetical country’s economy consists of three sectors: agriculture,
manufacturing, and services. The following table shows the data for each sector:
Sector Contribution to GDP (%) GDP (
$
in billions)
Agriculture 10% 50
Manufacturing 30% 200
Services 60% 500
Calculate the Gross Domestic Product (GDP) of the country.
Solution
Step 1: Calculate the contribution of each sector to GDP in dollars.
Agriculture: 10% of 50 billion dollars.
10% ×50 = 0.10 ×50 = 5 billion dollars
Manufacturing: 30% of 200 billion dollars.
30% ×200 = 0.30 ×200 = 60 billion dollars
Services: 60% of 500 billion dollars.
60% ×500 = 0.60 ×500 = 300 billion dollars
Step 2: Add up the GDP contributions of each sector to find the total GDP
of the country.
5 billion dollars + 60 billion dollars + 300 billion dollars = 365 billion dollars
Therefore, the Gross Domestic Product (GDP) of the country is 365 billion
dollars.
Question 2
Question
Suppose a country has the following data for a given year:
Consumption:
$
500 billion
Investment:
$
200 billion
Government spending:
$
150 billion
Exports:
$
100 billion
Imports:
$
80 billion
Calculate the Gross Domestic Product (GDP) of the country for this year.
Solution
To calculate the Gross Domestic Product (GDP) of the country, we can use the
expenditure approach formula:
GDP = C+I+G+ (X−M)
where: - Cis consumption, - Iis investment, - Gis government spending, - X
is exports, and - Mis imports.
Step 1: Calculate net exports (X−M):
X−M= 100 −80
= 20
Step 2: Plug in the values to the GDP formula:
GDP = 500 + 200 + 150 + 20
= 870 billion
Therefore, the Gross Domestic Product (GDP) of the country for the given
year is
$
870 billion.

Question 3
Question
Suppose a country’s GDP is calculated using the expenditure approach. The
following data is provided for a particular year:
Consumption expenditure:
$
500 billion
Investment expenditure:
$
200 billion
Government expenditure:
$
100 billion
Net exports:
$
50 billion
Calculate the country’s GDP for the year.
Solution
To calculate the Gross Domestic Product (GDP) using the expenditure ap-
proach, we need to sum up the total expenditure in the economy. The GDP
formula using the expenditure approach is as follows:
GDP = Consumption + Investment + Government Spending + Net Exports
Step 1: Substitute the given values into the GDP formula.
GDP = 500 billion + 200 billion + 100 billion + 50 billion
Step 2: Perform the addition to find the GDP.
GDP = 850 billion
Therefore, the country’s GDP for the year is
$
850 billion.

Consumption expenditure:
$
800 billion
Investment expenditure:
$
300 billion
Government expenditure:
$
400 billion
Exports:
$
200 billion
Imports:
$
150 billion
Calculate the Gross Domestic Product (GDP) of the country for this year.
3
Solution
Step 1: Calculate the Gross Domestic Product (GDP) using the expenditure
approach formula:
GDP = Consumption+Investment+Government Spending+(Exports−Imports)
Step 2: Substitute the given values into the formula:
GDP = $800 billion + $300 billion + $400 billion + ($200 billion −$150 billion)
Step 3: Perform the arithmetic operations:
GDP = $800 billion + $300 billion + $400 billion + $50 billion
Step 4: Add up all the components to find the GDP:
GDP = $800 billion + $300 billion + $400 billion + $50 billion = $1550 billion
Therefore, the Gross Domestic Product (GDP) of the country for this year
is
$
1550 billion.
Question 5
Question
Assume an economy produces only three goods: laptops, smartphones, and
tablets. The quantities produced and their corresponding prices are as follows:
Good Quantity Produced Price per Unit (
$
)
Laptops 500 800
Smartphones 1000 400
Tablets 800 300
Calculate the GDP of this economy using both the expenditure approach
and the income approach.
Solution
Let’s calculate the GDP of this economy using both the expenditure approach
and the income approach.
Expenditure Approach:
GDP = Consumption + Investment + Government Spending + Net Exports
Step 1: Calculate Consumption
Consumption = (500 ×800) + (1000 ×400) + (800 ×300)
= 400,000 + 400,000 + 240,000
= 1,040,000
4
Step 2: Calculate Investment (Assume investment in this economy
is
$
500,000)
Investment = 500,000
Step 3: Calculate Government Spending (Assume government
spending in this economy is
$
300,000)
Government Spending = 300,000
Step 4: Calculate Net Exports (Assume net exports in this econ-
omy is
$
100,000)
Net Exports = 100,000
Step 5: Calculate GDP
GDP = 1,040,000 + 500,000 + 300,000 + 100,000
= 1,940,000
Therefore, the GDP of this economy using the expenditure approach is
$
1,940,000.
Income Approach:
GDP = Wages + Rent + Interest + Profit
Step 1: Calculate Wages
Wages = (500 ×800) + (1000 ×400) + (800 ×300)
= 400,000 + 400,000 + 240,000
= 1,040,000
Step 2: Calculate Rent (Assume total rent in this economy is
$
100,000)
Rent = 100,000
Step 3: Calculate Interest (Assume total interest in this economy
is
$
50,000)
Interest = 50,000
Step 4: Calculate Profit (Assume total profit in this economy is
$
400,000)
Profit = 400,000
Step 5: Calculate GDP
GDP = 1,040,000 + 100,000 + 50,000 + 400,000
= 1,590,000
Therefore, the GDP of this economy using the income approach is
$
1,590,000.

Question 6
Question
Suppose a country’s economy has the following data for a particular year:
Consumption expenditure:
$
800 billion
Investment expenditure:
$
200 billion
Government expenditure:
$
300 billion
Exports:
$
150 billion
Imports:
$
120 billion
Calculate the Gross Domestic Product (GDP) of the country for that year.
Solution
To calculate the Gross Domestic Product (GDP), we can use the expenditure
approach formula:
GDP =C+I+G+ (X−M)
where: - Cis consumption expenditure, - Iis investment expenditure, - Gis
government expenditure, - Xis exports, and - Mis imports.
Step 1: Calculate the net exports (X−M).
X−M= 150 billion −120 billion
= 30 billion
Step 2: Substitute the given values into the GDP formula.
GDP = 800 billion + 200 billion + 300 billion + 30 billion
= 1330 billion
Therefore, the Gross Domestic Product (GDP) of the country for that year
is
$
1330 billion.

$
0.6 trillion
Calculate the GDP of the country for this year.
Solution
Step 1: Substitute the given values into the GDP formula.
GDP = 2.5+1+0.8 + (0.7−0.6)
Step 2: Perform the arithmetic operations.
GDP = 2.5+1+0.8+0.1
Step 3: Sum up the values to find the GDP.
GDP = 4.4 trillion
Therefore, the GDP of the country for the given year is
$
4.4 trillion.

Calculate the Gross Domestic Product (GDP) for this country for the given
year.
7
Solution
Step 1: The GDP can be calculated using the following formula:
GDP = Consumption+Investment+Government Spending+(Exports−Imports)
Step 2: Substituting the given values into the formula:
GDP = $600 billion + $300 billion + $200 billion + ($150 billion −$120 billion)
Step 3: Calculating the values within the parentheses:
GDP = $600 billion + $300 billion + $200 billion + $30 billion
Step 4: Adding all the components together:
GDP = $600 billion + $300 billion + $200 billion + $30 billion = $1130 billion
So, the Gross Domestic Product (GDP) for the given year is $1130 billion.

700 billion
Calculate the Gross Domestic Product (GDP) of the country for that year.
Solution
To calculate the Gross Domestic Product (GDP) of a country, we use the ex-
penditure approach which sums up the following components: household con-
sumption, government spending, gross private domestic investment, exports,
and subtracts imports.
Step 1: Calculate GDP using the expenditure approach.
GDP = Household consumption+Government spending+Gross private domestic investment+Exports−Imports
Step 2: Substitute the given values into the formula and calculate GDP.
GDP = $5,000 billion+$1,200 billion+$1,500 billion+$800 billion−$700 billion
GDP = $5,000 billion+$1,200 billion+$1,500 billion+$800 billion−$700 billion
GDP = $5,000 billion + $4,500 billion
GDP = $9,500 billion

Question 14
Question
Suppose a country’s economy produces the following in a year: - 50 cars at a
price of 20,000 each - 200 computers at a price of 1,000each−500smartphonesatapriceof500
each Calculate the Gross Domestic Product (GDP) of the country using the ex-
penditure approach.
Solution
Step 1: Calculate the total value of cars produced.
Total value of cars = 50 ×20,000 = $1,000,000
Step 2: Calculate the total value of computers produced.
Total value of computers = 200 ×1,000 = $200,000
11
Step 3: Calculate the total value of smartphones produced.
Total value of smartphones = 500 ×500 = $250,000
Step 4: Calculate the GDP using the expenditure approach.
GDP = Total value of cars+Total value of computers+Total value of smartphones
GDP = $1,000,000 + $200,000 + $250,000 = $1,450,000
Therefore, the Gross Domestic Product (GDP) of the country using the
expenditure approach is
$
1,450,000.
Question 15

Government Consumption Expenditure:
$
200 billion
Net Exports:
$
50 billion
Calculate the country’s GDP using the expenditure approach.
Solution
To calculate the country’s GDP using the expenditure approach, we sum up the
values of Personal Consumption Expenditure, Gross Private Domestic Invest-
ment, Government Consumption Expenditure, and Net Exports.
Step 1: Calculate the sum of the components.
Personal Consumption Expenditure + Gross Private Domestic Investment+
Government Consumption Expenditure + Net Exports
= $800 billion + $300 billion + $200 billion + $50 billion
= $1350 billion
Step 2: The country’s GDP using the expenditure approach is
$
1350 billion.
12
Question 16
Question
Calculate the Gross Domestic Product (GDP) using the following information:
Consumption expenditure:
$
500 billion
Investment expenditure:
$
200 billion
Government expenditure:
$
100 billion
Exports:
$
50 billion
Imports:
$
30 billion
Solution
Step 1: The GDP can be calculated using the formula:
GDP = Consumption + Investment + Government + Exports −Imports
Step 2: Substitute the given values into the GDP formula:
GDP = $500 billion + $200 billion + $100 billion + $50 billion −$30 billion
Step 3: Perform the calculation:
GDP = $820 billion −$30 billion
GDP = $790 billion
Therefore, the Gross Domestic Product (GDP) is
$
790 billion.
Question 17
Question
Suppose a country’s economy can be represented by the following information:
Consumption expenditures: $2,500
Investment expenditures: $1,000
Government purchases: $700
Exports: $600
Imports: $400
Calculate the Gross Domestic Product for this country.
13
Solution
To calculate the GDP, we can use the formula:
GDP = Consumption+Investment+Government Spending+(Exports−Imports)
Step 1: Calculate the value of exports minus imports.
Exports −Imports = $600 −$400 = $200
Step 2: Substitute the given values into the GDP formula.
GDP = $2,500 + $1,000 + $700 + $200
Step 3: Add up the values to find the Gross Domestic Product (GDP).
GDP = $2,500 + $1,000 + $700 + $200 = $4,400
Therefore, the Gross Domestic Product for this country is $4,400.
Question 18
Question
Suppose a country’s GDP is
$
10 trillion. The government expenditures are
$
2
trillion, household consumption is
$
5 trillion, imports are
$
1 trillion, and exports
are
$
1.5 trillion. Calculate the country’s GDP using the expenditure approach.
Solution
Step 1: The expenditure approach to GDP calculation is given by the formula:
GDP =C+I+G+ (X−M)
where: - Cis household consumption - Iis business investments - Gis
government expenditures - Xis exports - Mis imports
Step 2: Given that: - C= $5 trillion - G= $2 trillion - X= $1.5 trillion -
M= $1 trillion
we can substitute these values into the formula:
GDP = $5 + I+ $2 + ($1.5−$1)
Step 3: Simplify the equation:
GDP = $5 + I+ $2 + $0.5
Step 4: Combine like terms:
GDP = $7 + I
14
Step 5: We know that the country’s GDP is
$
10 trillion. So, we can substi-
tute this value into the equation:
$10 = $7 + I
Step 6: Solve for I:
I= $10 −$7
I= $3 trillion
Step 7: Now substitute the value of Iback into the formula to find the
country’s GDP:
GDP = $7 + $3
GDP = $10 trillion
Therefore, the country’s GDP using the expenditure approach is
$
10 trillion.
Question 19
Question
In a hypothetical economy, the following data represents the various components
of expenditure:
Consumption expenditure:
$
800 billion
Investment expenditure:
$
200 billion
Government expenditure:
$
300 billion
Net exports:
$
50 billion (exports - imports)
Calculate the Gross Domestic Product (GDP) using the expenditure ap-
proach.
Solution
Step 1: Calculate the total expenditure.
Total expenditure = Consumption + Investment + Government + Net exports
Total expenditure = 800 + 200 + 300 + 50 = 1350 billion USD
Step 2: GDP can be calculated using the formula:
GDP = Consumption+Investment+Government+Net exports+Net foreign factor income
15
Step 3: Since we are not given the net foreign factor income, we will use the
simplified formula for GDP using the expenditure approach:
GDP = Total expenditure = 1350 billion USD
Therefore, the Gross Domestic Product (GDP) of the hypothetical economy
is
$
1350 billion.
Question 20
Question
Suppose a country’s GDP in a particular year was
$
10 trillion. The components
of GDP for that year are as follows:
Consumption:
$
6 trillion
Investment:
$
2 trillion
Government spending:
$
1.5 trillion
Net exports:
$
0.5 trillion
Calculate the country’s GDP using the income approach.
Solution
The income approach to calculating GDP is based on the idea that all expen-
ditures eventually become income for someone. Using the income approach,
GDP can be calculated by adding up all the incomes earned in the production
of goods and services within a country.
Step 1: Calculate GDP using the income approach.
GDP = Compensation of employees + Gross operating surplus + Gross mixed income + Taxes on production and imports −Subsidies
GDP = $6 trillion + $2 trillion + $1.5 trillion + $0.5 trillion
GDP = $10 trillion
Therefore, the country’s GDP using the income approach is
$
10 trillion,
which matches the initial GDP of
$
10 trillion given in the question.
Question 21
Question
Let’s consider a hypothetical economy with the following data:
- Consumption expenditure:
$
800 billion - Investment expenditure:
$
200
billion - Government expenditure:
$
300 billion - Net exports:
$
50 billion -
Depreciation:
$
100 billion
Calculate the Gross Domestic Product (GDP) of this economy.
16
Solution
To calculate the Gross Domestic Product (GDP) of an economy, we sum up the
total value of all final goods and services produced within a country’s borders
in a specific time period.
Step 1: Calculate the GDP using the Expenditure Approach formula:
GDP = Consumption + Investment + Government Spending + Net Exports
Given: Consumption expenditure =
$
800 billion Investment expenditure =
$
200 billion Government expenditure =
$
300 billion Net exports =
$
50 billion
Substitute the values into the formula:
GDP = 800 + 200 + 300 + 50
Step 2: Calculate the GDP:
GDP = 1350 billion
Therefore, the Gross Domestic Product (GDP) of this economy is
$
1350
billion.
Question 22
Question
A country’s economy is composed of the following sectors: agriculture, man-
ufacturing, services, and government. The value added in each sector for a
given year is as follows: agriculture
$
500 million, manufacturing
$
800 million,
services
$
1200 million, and government
$
300 million. Calculate the Gross Do-
mestic Product (GDP) using the value added approach.
Solution
Step 1: Calculate the Gross Value Added (GVA) by summing the value added
in each sector.
GVA = Agriculture + Manufacturing + Services + Government
GVA = $500 million + $800 million + $1200 million + $300 million
GVA = $2800 million
Step 2: Calculate the GDP by adding taxes on products and subtracting
subsidies.
GDP = GVA + Taxes −Subsidies
Assuming there are no taxes on products and subsidies, the equation simplifies
to:
GDP = GVA
Therefore, the GDP of the country is
$
2800 million.

$
200 billion
Government expenditure:
$
150 billion
Exports:
$
100 billion
Imports:
$
80 billion
Calculate the Gross Domestic Product (GDP) using the expenditure approach.
Solution
Step 1: Calculate GDP using the expenditure approach formula:
GDP = C+I+G+ (X−M)
where:
C= Consumption expenditure
I= Investment expenditure
G= Government expenditure
X= Exports
M= Imports
Step 2: Substitute the given values into the formula:
GDP = 600 + 200 + 150 + (100 −80)
GDP = 600 + 200 + 150 + 20
GDP = 950 + 20
GDP = 970 billion
Therefore, the Gross Domestic Product (GDP) of the country for the given
year is
$
970 billion.
Question 24
Question
Suppose a country’s economy can be described by the following table:
18
Sector Production (in billion USD) Intermediate Consumption (in billion USD)
Agriculture 100 30
Manufacturing 200 50
Services 300 100
Construction 150 40
Calculate the Gross Domestic Product (GDP) for this country.
Solution
Step 1: Calculate the Value Added for each sector.
For Agriculture: 100 −30 = 70 billion USD
For Manufacturing: 200 −50 = 150 billion USD
For Services: 300 −100 = 200 billion USD
For Construction: 150 −40 = 110 billion USD
Step 2: Calculate the GDP using the Value Added approach.
GDP = Value AddedAgriculture+Value AddedManufacturing+Value AddedServices+Value AddedConstruction
GDP = 70 + 150 + 200 + 110 = 530 billion USD
Therefore, the Gross Domestic Product (GDP) for this country is 530 billion
USD.
Question 25
Question
Suppose a country has the following data for a given year:
Consumption expenditure:
$
500 billion
Investment expenditure:

$
150 billion
Exports:
$
100 billion
Imports:
$
80 billion
Calculate the Gross Domestic Product (GDP) of the country for the given
year.
19
Solution
Step 1: The GDP is calculated using the expenditure approach, which states
that GDP is the sum of consumption expenditure, investment expenditure, gov-
ernment expenditure, and net exports.
GDP =C+I+G+ (X−M)
where - Cis consumption expenditure, - Iis investment expenditure, - Gis
government expenditure, - Xis exports, and - Mis imports.
Step 2: Substituting the given values into the formula, we get
GDP = 500 + 200 + 150 + (100 −80)
Step 3: Calculating the net exports
GDP = 500 + 200 + 150 + 20
Step 4: Adding all the values together
GDP = 500 + 200 + 150 + 20 = 870
Therefore, the Gross Domestic Product (GDP) of the country for the given
year is
$
870 billion.
Question 26
Question

Consumption expenditure = 500 billion
Investment expenditure = 200 billion
Government expenditure = 300 billion
Exports = 100 billion
Imports = 50 billion
Calculate the Gross Domestic Product (GDP) for this country for the given
year.
Solution
Step 1: Calculate Net Exports.
Net Exports = Exports −Imports = 100 billion −50 billion = 50 billion
20
Step 2: Use the expenditure approach to calculate the GDP.
GDP = Consumption + Investment + Government Expenditure + Net Exports

country is 1050 billion dollars.
Question 27
Question
Suppose that a country’s economy can be represented by the following data:
Consumption spending:
$
500 billion
Investment spending:
$
200 billion
Government purchases:
$
100 billion
Exports:
$
50 billion
Imports:
$
70 billion
Calculate the Gross Domestic Product (GDP) of the country using the ex-
penditure approach.
Solution
To calculate the Gross Domestic Product (GDP) using the expenditure ap-
proach, we need to sum up all the components of spending in the economy:
Step 1: Calculate GDP using the expenditure approach
GDP = Consumption + Investment + Government Purchases + Net Exports
= $500 billion + $200 billion + $100 billion + (Exports −Imports)
= $500 billion + $200 billion + $100 billion + ($50 billion −$70 billion)
= $500 billion + $200 billion + $100 billion + (−$20 billion)
= $500 billion + $200 billion + $100 billion −$20 billion
= $780 billion
Therefore, the Gross Domestic Product (GDP) of the country using the
expenditure approach is

Step 2: Substituting the given values into the formula:
GDP = 700 + 200 + 300 + (150 −120)
Step 3: Calculate the exports minus imports:
Exports −Imports = 150 −(−120) = 150 + 120 = 270
Step 4: Substitute this value back into the GDP formula:
GDP = 700 + 200 + 300 + 270
Step 5: Calculate the total GDP:
GDP = 700 + 200 + 300 + 270 = 1470 billion dollars
Therefore, the country’s GDP for the year 2020 is 1470 billion dollars.

Question 34
Question
Suppose a country’s economy can be described by the following equations: -
Consumption (C) = 800 + 0.6Y- Investment (I) = 200 + 0.2Y- Government
spending (G) = 500 - Net exports (NX) = 100 −0.1Ywhere Yrepresents the
country’s GDP. Calculate the equilibrium GDP for this economy.
Solution
Step 1: The equilibrium GDP occurs when aggregate output equals aggregate
expenditure. Mathematically, this is represented as:
Y=C+I+G+NX
Step 2: Substitute the given equations for C,I,G, and NX into the equi-
librium GDP equation:
Y= (800 + 0.6Y) + (200 + 0.2Y) + 500 + (100 −0.1Y)
Step 3: Simplify the equation by combining like terms:
Y= 800 + 0.6Y+ 200 + 0.2Y+ 500 + 100 −0.1Y
Y= 1600 + 0.7Y
Step 4: Subtract 0.7Y from both sides of the equation:
Y−0.7Y= 1600
0.3Y= 1600
Step 5: Divide both sides by 0.3 to solve for Y:
Y=1600
0.3
Y= 5333.33
Therefore, the equilibrium GDP for this economy is
$
5333.33.

$
)
Laptops 500 800
Smartphones 1000 400
Tablets 800 300
Calculate the GDP of this economy using both the expenditure approach
and the income approach.
Solution
Let’s calculate the GDP of this economy using both the expenditure approach
and the income approach.
Expenditure Approach:
GDP = Consumption + Investment + Government Spending + Net Exports
Step 1: Calculate Consumption
Consumption = (500 ×800) + (1000 ×400) + (800 ×300)
= 400,000 + 400,000 + 240,000
= 1,040,000
4
Step 2: Calculate Investment (Assume investment in this economy
is
$
500,000)
Investment = 500,000
Step 3: Calculate Government Spending (Assume government
spending in this economy is
$
300,000)
Government Spending = 300,000
Step 4: Calculate Net Exports (Assume net exports in this econ-
omy is
$
100,000)
Net Exports = 100,000
Step 5: Calculate GDP
GDP = 1,040,000 + 500,000 + 300,000 + 100,000
= 1,940,000
Therefore, the GDP of this economy using the expenditure approach is
$
1,940,000.
Income Approach:
GDP = Wages + Rent + Interest + Profit
Step 1: Calculate Wages
Wages = (500 ×800) + (1000 ×400) + (800 ×300)
= 400,000 + 400,000 + 240,000
= 1,040,000
Step 2: Calculate Rent (Assume total rent in this economy is
$
100,000)
Rent = 100,000
Step 3: Calculate Interest (Assume total interest in this economy
is
$
50,000)
Interest = 50,000
Step 4: Calculate Profit (Assume total profit in this economy is
$
400,000)
Profit = 400,000
Step 5: Calculate GDP
GDP = 1,040,000 + 100,000 + 50,000 + 400,000
= 1,590,000
Therefore, the GDP of this economy using the income approach is

government expenditure, - Xis exports, and - Mis imports.
Step 1: Calculate the net exports (X−M).
X−M= 150 billion −120 billion
= 30 billion
Step 2: Substitute the given values into the GDP formula.
GDP = 800 billion + 200 billion + 300 billion + 30 billion
= 1330 billion
Therefore, the Gross Domestic Product (GDP) of the country for that year
is
$
1330 billion.

Step 1: Calculate the value of exports minus imports.
Exports −Imports = $600 −$400 = $200
Step 2: Substitute the given values into the GDP formula.
GDP = $2,500 + $1,000 + $700 + $200
Step 3: Add up the values to find the Gross Domestic Product (GDP).
GDP = $2,500 + $1,000 + $700 + $200 = $4,400

Question 18
Question
Suppose a country’s GDP is
$
10 trillion. The government expenditures are
$
2
trillion, household consumption is
$
5 trillion, imports are
$
1 trillion, and exports
are
$
1.5 trillion. Calculate the country’s GDP using the expenditure approach.
Solution
Step 1: The expenditure approach to GDP calculation is given by the formula:
GDP =C+I+G+ (X−M)
where: - Cis household consumption - Iis business investments - Gis
government expenditures - Xis exports - Mis imports
Step 2: Given that: - C= $5 trillion - G= $2 trillion - X= $1.5 trillion -
M= $1 trillion
we can substitute these values into the formula:
GDP = $5 + I+ $2 + ($1.5−$1)
Step 3: Simplify the equation:
GDP = $5 + I+ $2 + $0.5
Step 4: Combine like terms:
GDP = $7 + I
14
Step 5: We know that the country’s GDP is
$
10 trillion. So, we can substi-
tute this value into the equation:
$10 = $7 + I
Step 6: Solve for I:
I= $10 −$7
I= $3 trillion
Step 7: Now substitute the value of Iback into the formula to find the
country’s GDP:
GDP = $7 + $3
GDP = $10 trillion
Therefore, the country’s GDP using the expenditure approach is
$
10 trillion.
Question 19
Question
In a hypothetical economy, the following data represents the various components
of expenditure:
Consumption expenditure:
$

50 billion (exports - imports)
Calculate the Gross Domestic Product (GDP) using the expenditure ap-
proach.
Solution
Step 1: Calculate the total expenditure.
Total expenditure = Consumption + Investment + Government + Net exports
Total expenditure = 800 + 200 + 300 + 50 = 1350 billion USD
Step 2: GDP can be calculated using the formula:
GDP = Consumption+Investment+Government+Net exports+Net foreign factor income
15
Step 3: Since we are not given the net foreign factor income, we will use the
simplified formula for GDP using the expenditure approach:

0.5 trillion
Calculate the country’s GDP using the income approach.
Solution
The income approach to calculating GDP is based on the idea that all expen-
ditures eventually become income for someone. Using the income approach,
GDP can be calculated by adding up all the incomes earned in the production
of goods and services within a country.
Step 1: Calculate GDP using the income approach.
GDP = Compensation of employees + Gross operating surplus + Gross mixed income + Taxes on production and imports −Subsidies
GDP = $6 trillion + $2 trillion + $1.5 trillion + $0.5 trillion
GDP = $10 trillion
Therefore, the country’s GDP using the income approach is
$
10 trillion,
which matches the initial GDP of
$
10 trillion given in the question.
Question 21
Question
Let’s consider a hypothetical economy with the following data:
- Consumption expenditure:
$
800 billion - Investment expenditure:
$
200
billion - Government expenditure:
$
300 billion - Net exports:
$
50 billion -
Depreciation:
$
100 billion
Calculate the Gross Domestic Product (GDP) of this economy.
16
Solution
To calculate the Gross Domestic Product (GDP) of an economy, we sum up the
total value of all final goods and services produced within a country’s borders
in a specific time period.
Step 1: Calculate the GDP using the Expenditure Approach formula:
GDP = Consumption + Investment + Government Spending + Net Exports
Given: Consumption expenditure =
$
800 billion Investment expenditure =
$
200 billion Government expenditure =
$
300 billion Net exports =
$
50 billion
Substitute the values into the formula:
GDP = 800 + 200 + 300 + 50
Step 2: Calculate the GDP:
GDP = 1350 billion
Therefore, the Gross Domestic Product (GDP) of this economy is
$
1350
billion.
Question 22
Question
A country’s economy is composed of the following sectors: agriculture, man-
ufacturing, services, and government. The value added in each sector for a
given year is as follows: agriculture
$
500 million, manufacturing
$
800 million,
services
$
1200 million, and government
$
300 million. Calculate the Gross Do-
mestic Product (GDP) using the value added approach.
Solution
Step 1: Calculate the Gross Value Added (GVA) by summing the value added
in each sector.
GVA = Agriculture + Manufacturing + Services + Government
GVA = $500 million + $800 million + $1200 million + $300 million
GVA = $2800 million
Step 2: Calculate the GDP by adding taxes on products and subtracting
subsidies.
GDP = GVA + Taxes −Subsidies
Assuming there are no taxes on products and subsidies, the equation simplifies
to:
GDP = GVA
Therefore, the GDP of the country is
$
2800 million.

Question 23
Question
In a country, the following data is provided for a certain year:
Consumption expenditure:
$
600 billion
Investment expenditure:
$
200 billion
Government expenditure:
$
150 billion
Exports:
$
100 billion
Imports:
$
80 billion
Calculate the Gross Domestic Product (GDP) using the expenditure approach.
Solution
Step 1: Calculate GDP using the expenditure approach formula:
GDP = C+I+G+ (X−M)
where:
C= Consumption expenditure
I= Investment expenditure
G= Government expenditure
X= Exports
M= Imports
Step 2: Substitute the given values into the formula:
GDP = 600 + 200 + 150 + (100 −80)
GDP = 600 + 200 + 150 + 20
GDP = 950 + 20
GDP = 970 billion
Therefore, the Gross Domestic Product (GDP) of the country for the given
year is
$
970 billion.
Question 24
Question
Suppose a country’s economy can be described by the following table:
18
Sector Production (in billion USD) Intermediate Consumption (in billion USD)
Agriculture 100 30
Manufacturing 200 50
Services 300 100
Construction 150 40
Calculate the Gross Domestic Product (GDP) for this country.
Solution
Step 1: Calculate the Value Added for each sector.
For Agriculture: 100 −30 = 70 billion USD
For Manufacturing: 200 −50 = 150 billion USD
For Services: 300 −100 = 200 billion USD
For Construction: 150 −40 = 110 billion USD
Step 2: Calculate the GDP using the Value Added approach.
GDP = Value AddedAgriculture+Value AddedManufacturing+Value AddedServices+Value AddedConstruction
GDP = 70 + 150 + 200 + 110 = 530 billion USD
Therefore, the Gross Domestic Product (GDP) for this country is 530 billion
USD.

$
150 billion
Exports:
$
100 billion
Imports:
$
80 billion
Calculate the Gross Domestic Product (GDP) of the country for the given
year.
19
Solution
Step 1: The GDP is calculated using the expenditure approach, which states
that GDP is the sum of consumption expenditure, investment expenditure, gov-
ernment expenditure, and net exports.
GDP =C+I+G+ (X−M)
where - Cis consumption expenditure, - Iis investment expenditure, - Gis
government expenditure, - Xis exports, and - Mis imports.
Step 2: Substituting the given values into the formula, we get
GDP = 500 + 200 + 150 + (100 −80)
Step 3: Calculating the net exports
GDP = 500 + 200 + 150 + 20
Step 4: Adding all the values together
GDP = 500 + 200 + 150 + 20 = 870
Therefore, the Gross Domestic Product (GDP) of the country for the given
year is
$
870 billion.
Question 26
Question
Suppose a country has the following data for a given year:
Consumption expenditure = 500 billion
Investment expenditure = 200 billion
Government expenditure = 300 billion
Exports = 100 billion
Imports = 50 billion
Calculate the Gross Domestic Product (GDP) for this country for the given
year.
Solution
Step 1: Calculate Net Exports.
Net Exports = Exports −Imports = 100 billion −50 billion = 50 billion
20
Step 2: Use the expenditure approach to calculate the GDP.
GDP = Consumption + Investment + Government Expenditure + Net Exports
GDP = 500 billion + 200 billion + 300 billion + 50 billion
GDP = 1050 billion
Therefore, the Gross Domestic Product (GDP) for the given year in this
country is 1050 billion dollars.

$
50 billion
Imports:
$
70 billion
Calculate the Gross Domestic Product (GDP) of the country using the ex-
penditure approach.
Solution
To calculate the Gross Domestic Product (GDP) using the expenditure ap-
proach, we need to sum up all the components of spending in the economy:
Step 1: Calculate GDP using the expenditure approach
GDP = Consumption + Investment + Government Purchases + Net Exports
= $500 billion + $200 billion + $100 billion + (Exports −Imports)
= $500 billion + $200 billion + $100 billion + ($50 billion −$70 billion)
= $500 billion + $200 billion + $100 billion + (−$20 billion)
= $500 billion + $200 billion + $100 billion −$20 billion
= $780 billion
Therefore, the Gross Domestic Product (GDP) of the country using the
expenditure approach is
$
780 billion.

Component Amount (in billions)
Consumption 700
Investment 200
Government spending 300
Exports 150
Imports −120
Calculate the country’s GDP for the year 2020.
22
Solution
Step 1: To calculate GDP, we use the formula:
GDP = Consumption+Investment+Government spending+(Exports−Imports)
Step 2: Substituting the given values into the formula:
GDP = 700 + 200 + 300 + (150 −120)
Step 3: Calculate the exports minus imports:
Exports −Imports = 150 −(−120) = 150 + 120 = 270
Step 4: Substitute this value back into the GDP formula:
GDP = 700 + 200 + 300 + 270
Step 5: Calculate the total GDP:
GDP = 700 + 200 + 300 + 270 = 1470 billion dollars
Therefore, the country’s GDP for the year 2020 is 1470 billion dollars.

Question 34
Question
Suppose a country’s economy can be described by the following equations: -
Consumption (C) = 800 + 0.6Y- Investment (I) = 200 + 0.2Y- Government
spending (G) = 500 - Net exports (NX) = 100 −0.1Ywhere Yrepresents the
country’s GDP. Calculate the equilibrium GDP for this economy.
Solution
Step 1: The equilibrium GDP occurs when aggregate output equals aggregate
expenditure. Mathematically, this is represented as:
Y=C+I+G+NX
Step 2: Substitute the given equations for C,I,G, and NX into the equi-
librium GDP equation:
Y= (800 + 0.6Y) + (200 + 0.2Y) + 500 + (100 −0.1Y)
Step 3: Simplify the equation by combining like terms:
Y= 800 + 0.6Y+ 200 + 0.2Y+ 500 + 100 −0.1Y
Y= 1600 + 0.7Y
Step 4: Subtract 0.7Y from both sides of the equation:
Y−0.7Y= 1600
0.3Y= 1600
Step 5: Divide both sides by 0.3 to solve for Y:
Y=1600
0.3
Y= 5333.33
Therefore, the equilibrium GDP for this economy is
$
5333.33.
