a. Approximate real rate of interest 4.23%
b. Exact real rate of interest 2.78%
a. Calculations to determine the approximate real rate of interest in percent.
Using this formula
Approximate real rate of interest=Risk free rate - Inflation rate
Let plug in the formula
Approximate real rate of interest = 9.44% - 5.21%
Approximate real rate of interest = 4.23%
b. Calculations to determine the exact real rate of interest in percent
Using this formula
Exact real rate of interest= (Risk free rate-inflation) / (1+inflation)
Let plug in the formula
Exact real rate of interest= (9.44% - 5.21%) / (1 + 5.21%)
Exact real rate of interest=4.23% / 1.521%
Exact real rate of interest= 2.78%
Inconclusion:
a. Approximate real rate of interest 4.23%
b. Exact real rate of interest 2.78%
