Answer 1

i. real GDP for each year using 2004 as the base year.

Real GDP = Quantity $\times$ price of the base year

$2004 \\ (500\times 20) + (220\times 10) + (800\times 30) = \$36200\\ 2005 \\ (510\times 20) + (600\times 10) + (700\times 30) = \$37200\\ 2006 \\(550\times 20) + (580\times 10) + (750\times 30) = \$39300$

ii. Calculate the GDP deflator for each year taking 2004 as the base year.

GDP deflator = [Nominal GDP $\div$ Real GDP (base year)] $\times$ 100

$2004 \\ (\frac{36200 } {36200}) \times 100 = 100\\ 2005 \\ (\frac{44450 } {36200}) \times 100 = 123\\ 2006 \\ (\frac{51540 }{36200}) \times 100 = 142$

Calculation of Nominal GDP = Quantity $\times$ Price

$2004 \\(500\times 20) + (220\times 10) + (800\times 30) = \$36200\\ 2005 \\ (510\times 25) + (600\times 12) + (700\times 35) = \$44450\\ 2006 \\(550\times 27) + (580\times 18) + (750\times 35) = \$51540$

iii. Calculate the GDP growth rates for the year 2005 and 2006.

GDP growth rate = (GDP of present year - GDP of base year} $\div$ GDP of base year

$2005 \\\frac{\$37200 - \$36200} { \$36200} = 2.76\%\\ 2006 \\\frac{ \$39300 - \$36200 }{ \$36200} = 8.56\%$
