The inflation rate is 16.67%. To find this, we first need to compute the GDP deflator for each year and then we need to calculate the percent change in the GDP deflator. The GDP deflator is given by GDPdef=(nominal GDP/Real GDP)*100. For the first year, the GDP deflator is 120. For the second year it is 140. Percent change is given by [(new value - old value)/old value]*100. Plugging in 140 for the new value and and 120 for the old value, we see get that the percent change is 16.6667. Thus the inflation rate is approximately 16.67%.
