In year 1, 2, and 3, two products are produced in an economy: apple and oranges. The quantities and prices for each good in each year are listed in the table below:

(a) Calculate the growth rate of real GDP from year 1 to year 2 and that from year 2 to year 3 using the chain-weighting method. 1 (b) Calculate the real GDPs of year 1,2, and 3 using the chain-weighting method. Use year 2 as the base year. (c) Compute the implicit GDP price deflator for each year using the base-year method. Use year 3 as the base year. (d) Compute the CPI index for each year. Use year 1 as the base year.
