Answer:
8%
Step-by-step explanation:
Data provided in the given question
Cash = 400
The computation of annual rate of interest is shown below:-
Semi annual coupon rate
= 400 ÷ 10,000
= 4%
So, Annual rate of interest
= 4% × 2
= 8%
Therefore, as per the question for calculating the annual rate of interest we simply multiply semi annual coupon rate with semi annual interest.
