which of the following item is not included in measuring national income by the income approach?

The income approach is one of the methods used to measure the national income of a country. It calculates the total income earned by all factors of production in the country during a given period of time. Out of the options given, student's grants and scholarships are not included in measuring national income by the income approach. This is because grants and scholarships are considered transfers of income, which means they are not earned through the production of goods or services. Therefore, student's grants and scholarships are not included in the calculation of national income by the income approach, while wages and salaries of public servants, profits of companies, income earned by self-employed persons such as lawyers, and rents on property are included.
