01 If NNP is 840 and depreciation is 90, what will GNP be?
Answer and explanation
Correct answer: C. 930
Explanation: NNP is obtained from GNP by subtracting depreciation: NNP = GNP − Depreciation. To recover the gross measure, add depreciation back. Therefore, GNP = 840 + 90 = 930. Subtracting would move in the wrong direction, while using 840 or 90 alone would ignore one part of the relationship. The calculation assumes both figures use the same valuation basis.
