A 3 * 4+0 in nominal year 65438 = 4 * 5 = 20 in the second year and 5*6=30 in the third year.

B. Real GDP: 3 * 4 = 1 year, 4 * 4 = 12 years, 5*4=20 years.

C.GDP deflator:12/12 *100 =100 in the first year, and 20/16 *100 =100 in the second year.

30/20* 100= 150 in the third year.

D. The real GDP has increased by (20- 16)/ 16=25%.

E. inflation rate = (150-125)/125 *100 = 20%.

F. Yes

Because only one product is produced, the real GDP can only be measured by output.

The real GDP has increased by (5-4)/4=25%.

Because there is only one commodity, the inflation rate can be measured by the price of that commodity.

(6-5)/5=20%

If it is a variety of commodities, it may not be possible unless its output increases in proportion.
