Answer:
rate = 5.24 %
so correct option is d. 5.24%
Explanation:
given data
purchased bond initial amount = $3,000
Maturity amount = $5,000
time period = 10 years
to find out
interest rate earn on this bond
solution
we know here initial amount and final amount with time period so
we will apply here Maturity amount formula that is
Maturity amount = initial amount × [tex](1+rare)^{time}[/tex] .................1
put here value we get
Maturity amount = initial amount × [tex](1+rare)^{time}[/tex]
5000 = 3000 × [tex](1+rare)^{10}[/tex]
1.6667 - 1 = [tex](rare)^{10}[/tex]
solve it we get
rate = 5.24 %
so correct option is d. 5.24%
