01 If the GDP deflator is 110 in one year and 132 in the next, what is the percentage rise in the price level?
Answer and explanation
Correct answer: A. 20 percent
Explanation: The governing concept is percentage change in a price index, calculated relative to the initial value. The index rises from 110 to 132, so the increase is 132 − 110 = 22 points. Dividing by the original index gives (22 ÷ 110) × 100 = 20%. Therefore, option A is correct. Option B confuses the index-point increase with the percentage increase, while options C and D use incorrect bases or calculations.
