Q: Which formula correctly represents the GDP deflator?

$$GDP\ deflator = \frac{Nominal\ GDP}{Real\ GDP} \times 100$$

Q: If nominal GDP in 2020 is $$2,000 billion and real GDP in 2020 (using 2010 as the base year) is 1$$,600 billion, what is the GDP deflator for 2020?

$$GDP\ deflator = \frac{2,000}{1,600} \times 100 = 125$$

Q: If the price level in the base year is 100, and the price level in the current year is 120, what is the inflation rate over this period?

$$\frac{120-100}{100} \times 100 = 20\%$$
