The following data represents the income of a country for a year: 
Calculate the National Income (NI) of the country.
7500 Crores
To determine National Income (NI), we will utilize the provided data and the relevant formula.
- Net Domestic Product (NDP) at Market Price: The total market value of goods and services produced domestically.
- Indirect Taxes: Taxes levied on goods and services, increasing their market price.
- Subsidies: Government payments that reduce the cost of goods and services.
- Depreciation: The decrease in the value of capital assets over time.
- National Income (NI): Defined as NDP at factor cost, calculated as:
\[
\text{NI} = \text{NDP at Market Price} - \text{Indirect Taxes} + \text{Subsidies}
\]
NDP at Market Price = 8000 crores
Indirect Taxes = 1000 crores
Subsidies = 500 crores
Depreciation = 600 crores (Note: Depreciation is not directly used in this NI calculation)
\[ \text{NI} = 8000 - 1000 + 500 = 7500 \text{ crores} \]
The calculated National Income (NI) for the country is 7500 crores.
