Step 1: Understanding the Concept:
Stock variables are measured at a specific point in time.
Flow variables are measured over a period of time.
Step 2: Detailed Explanation:
1. Total National Income at the end of the year (₹ 80,000 crore): This is a Stock variable because it is specified at a particular point in time (at the end of the year).
2. Increase in GDP (₹ 2,00,000 crore): This is a Flow variable because the word "increase" implies a change occurring "during the year" (a period of time).
3. Price Index for capital goods at the end of the year: This is a Stock variable as it represents the price level at a specific point in time.
4. Investment in new capital goods (₹ 8,000 crore): This is a Flow variable because investment is the addition to the stock of capital made during a particular period.
Step 3: Final Answer:
Stock variables: National Income (at a point), Price Index.
Flow variables: Increase in GDP, Investment.
B
Step 1: Understanding the Concept:
The GNP Deflator (or Price Index) measures the change in the price level of all goods and services produced in an economy relative to a base year.
Step 2: Key Formula or Approach:
\[ \text{GNP Deflator} = \frac{\text{Nominal GNP}}{\text{Real GNP}} \times 100 \]
Step 3: Detailed Explanation:
Given:
Nominal GNP (Current Prices) = ₹ 2,500 crore
Real GNP (Base Year Prices) = ₹ 3,000 crore
Calculation:
\[ \text{GNP Deflator} = \frac{2500}{3000} \times 100 \]
\[ \text{GNP Deflator} = \frac{25}{30} \times 100 = \frac{5}{6} \times 100 \]
\[ \text{GNP Deflator} \approx 83.33% \]
Step 4: Final Answer:
The GNP deflator is approximately 83.33%.
C
Step 1: Understanding the Concept:
We use the GNP Deflator calculated in the previous part to assess the change in the price level.
Step 2: Detailed Explanation:
The base year price index is always taken as 100.
In this case, the calculated GNP Deflator is 83.33%.
Since 83.33% < 100%, it means the general price level has fallen by approximately 16.67% (100 - 83.33) compared to the base year.
Therefore, the statement that "the price level has risen" is factually incorrect based on the data provided.
Step 3: Final Answer:
Refuted. The price level has fallen, not risen, as indicated by a deflator value less than 100.
