The national income is ₹475 crores.
Private Income = 120 + (-5) - 20 + 100 = 195
Personal Income = Private Income - Undistributed Profit
Personal Income = 195 - 20 = 175
Corporate Income = Corporation Tax - Undistributed Profit
Corporate Income = 20 - (-5) = 25
Government Income = Personal Tax + Corporation Tax + Net Indirect Tax
Government Income = 150 + 20 + 100 = 270
Net Foreign Factor Income = Net Factor Income to Abroad - Net Imports
Net Foreign Factor Income = (-5) - (-10) = 5
The national income is:
= 175 + 25 + 270 + 5
= ₹475 crores.
