Explanation:
GDP is a measure of the sum value of a country's output in a given period. The GDP value reflects economic growth or decline in a country for the period under review.
GDP is calculated using three methods. They include the income, production, and expenditure approach.
In the Income approach, economists add up all the earnings from the factors of production. Wages and salaries of all employees; the profits from businesses and corporates' ; rents, and interests form landlords are summed up to get GDP. Adjustments are made to cater for the taxes paid to the relevant government agencies. ( 4th option)
The production approach involves getting the value of all the finished consumer goods and services in the economy. The approach excludes intermediary goods and work-n progress. GDP is obtained by adding the total of the finished products and services and multiplying them by their prices. (3rd option)
The consumption option applies a formula that GDP = C+G+I+ NX, where C is private consumption expenditure, G is government consumption and investment expenditure, and I in private investment expenditure. NX is the net imports. ( 1 st option )
