Answer:
10.24%
Explanation:
The computation of the firm an annual interest is shown below:
= {(1 + annual interest rate) × (1 + inflation rate) - 1}
= {(1 + 6%) × (1 + 4%) - 1}
= (1.06 × 1.04) - 1
= 1.1024 - 1
= 10.24%
All other information which is given is not relevant. Hence, ignored it
We simply multiply the annual interest rate and the rate of inflation and than subtract it by 1 so that the accurate annual interest rate can come.
