Answer:
3.4%
Explanation:
Data provided in the question:
Normal rate of return = 6.5%
Expected Inflation rate = 3.1 %
Now,
The real risk-free rate of interest is given as
Real risk-free rate of interest = Normal rate of return - Expected Inflation rate
Therefore,
Real risk-free rate of interest = 6.5% - 3.1%
or
Real risk-free rate of interest = 3.4%
