Answer 1

The Correct Option is C

Concept:
National income accounting measures the total economic output of an economy across the circular flow of income using three distinct methodologies, which yield identical aggregate values in equilibrium.

Step 1: Identifying the Three Measurement Approaches:
1. Product (or Output/Value Added) Method: Measures national income by computing the net contribution of every producing enterprise across primary, secondary, and tertiary sectors, avoiding double counting by subtracting intermediate consumption.
2. Income Method: Measures aggregate national income at the stage of factor payments, summing compensation of employees, rent, interest, and profits earned by owners of factors of production.
3. Expenditure Method: Measures final expenditures on gross domestic product, summing private consumption expenditure, government consumption expenditure, gross domestic capital formation, and net exports.

Step 2: Evaluating the Options:
Product, Income, and Expenditure are the three standard methods established in macroeconomic theory.
Options including investment, disposable income, or separating value added from product method do not represent the classic three distinct methods.
Final Answer:
The three standard methods are the Product, Income, and Expenditure methods, corresponding to Option (C).

Answer 2

Concept:
Real GDP measures the value of all final goods and services produced in an economy evaluated at constant base-year prices, thereby isolating physical output growth from price fluctuations.

Step 1: Mathematical Formula for Real GDP:
Real GDP of the current year ($t$) evaluated at base year ($0$) prices is given by:
\[ \text{Real GDP}_t = Q_t \times P_0 \] where:
$Q_t$ = Physical output produced in the current year ($2021$),
$P_0$ = Price prevailing in the base year ($2020$).

Step 2: Calculation using Given Values:
From the given data:
Current year ($2021$) quantity, $Q_{2021} = 310\text{ kg}$.
Base year ($2020$) price, $P_{2020} = \text{Rs } 20\text{ per kg}$.
Current year ($2021$) price, $P_{2021} = \text{Rs } 30\text{ per kg}$.
Applying the values into the formula:
\[ \text{Real GDP}_{2021} = 310 \times 20 = \text{Rs } 6200 \]

Step 3: Verification of Other Values:
The Nominal GDP for 2021 would be $Q_{2021} \times P_{2021} = 310 \times 30 = \text{Rs } 9300$.
The GDP for 2020 was $200 \times 20 = \text{Rs } 4000$.
The question asks specifically for the Real GDP of 2021, which is $\text{Rs } 6200$.
Final Answer:
India's real GDP for the year 2021 is Rs. 6200, corresponding to Option (B).

Answer 3

Concept:
The GDP deflator is an index of price changes for goods and services included in GDP. It measures the ratio of nominal GDP to real GDP.

Step 1: Formula for the GDP Deflator:
The GDP deflator expressed in percentage terms is defined as:
\[ \text{GDP Deflator} = \left( \frac{\text{Nominal GDP}}{\text{Real GDP}} \right) \times 100 \]

Step 2: Computing Values from Question 42:
From Question 42, the relevant output and price values for 2021 are:
1. Nominal GDP in 2021:
\[ \text{Nominal GDP}_{2021} = Q_{2021} \times P_{2021} = 310 \times 30 = \text{Rs } 9300 \] 2. Real GDP in 2021 (calculated using base year 2020 price):
\[ \text{Real GDP}_{2021} = Q_{2021} \times P_{2020} = 310 \times 20 = \text{Rs } 6200 \]

Step 3: Calculating GDP Deflator:
Substituting the nominal and real GDP into the deflator formula:
\[ \text{GDP Deflator} = \left( \frac{9300}{6200} \right) \times 100 = 1.5 \times 100 = 150\% \] This value indicates that the price level of goods produced in 2021 has risen by 50 percent relative to the base year 2020.
Final Answer:
Therefore, the GDP Deflator in percentage terms is 150 Percent, matching Option (A).

Answer 4

Concept:
National income accounts typically capture transactions that take place through organized market mechanisms involving monetary remuneration.
Productive activities that occur without financial exchange are omitted from GDP, which can lead to an underestimation of true economic welfare.

Step 1: Understanding Non-Monetary Exchanges:
Domestic services performed by women and other household members, such as cooking, childcare, cleaning, and caring for the elderly, create economic value and well-being.
However, because these services are rendered out of natural affection, familial duty, or community traditions without monetary payment, they are classified as non-monetary exchanges.
Because there is no market valuation or transaction trail, national income accounting conventions exclude these unpriced household activities from official GDP calculations.

Step 2: Evaluating Other Options:
Such domestic tasks are not included in official GDP due to the absence of a market price.
Externalities refer to unintended third-party benefits (positive) or costs (negative) generated by an economic activity without corresponding payment or compensation; domestic household work does not fit this definition.
Final Answer:
Hence, domestic services performed at home represent Non-monetary Exchanges.

Answer 5

Concept:
Comprehension-based questions require verifying each statement against the factual assertions presented in the passage.

Step 1: Analyzing the Passage Text:
The passage explicitly states:
"The Consumer Price Index (CPI) and Wholesale Price Index (WPI) are the other important ways to measure change of prices in an economy."
This matches Statement (B) directly.

Step 2: Checking the Incorrect Statements:
Statement (A) contradicts the text, which states: "we take the help of real GDP instead of relying on current market prices."
Statement (C) inverts the ratio defined in the text, which specifies that "The ratio of nominal GDP to real GDP gives us an idea of how prices have moved."
Statement (D) contradicts the passage, which points out that "non-monetary exchanges are not accounted as part of economic activity."
Final Answer:
Therefore, the only correct statement consistent with the passage is Option (B).
