The base year is 2018 for CPI and real GDP calculation.
The fixed basket for CPI = 6 bananas + 5 coconuts.
Please find
(a) Price of banana in 2018 (4%)
Nominal GDP in 2018 = 15*a+20*20=775 → a =25
(b) Price of coconut in 2019 (4%)
Basket in 2018 = 6*25+5*20=250
Basket in 2019 = 6*35+5*b= 210+5b
CPI in 2019 = (210+5b)/250*100=144 → b=30
(c) Quantity of banana in 2019 (4%)
Nominal GDP in 2019 = c*35+40*30=2075 → c =25
(d) GDP deflator in 2019 (4%)
Real GDP in 2019 = 25*25+40*20=1425 GDP
deflator in 2019 =2075/1425*100=145.61 → d =145.61
(e) What is the CPI inflation rate? (5%)
(144-100)/100*100%=44%
