Explanation / Answer

Let principal be $1000

Hence simple interest=Principal*Interest Rate*Time Period

=$1000*8.7%*9 years

=$783

Hence future value=principal+simple interest

=(1000+783)

=$1783

Hence for First Complex Bank:

We use the formula:
A=P(1+r/100)^n
where
A=future value
P=present value
r=rate of interest
n=time period.

1783=1000*(1+r/100)^9

(1783/1000)^(1/9)=(1+r/100)

(1+r/100)=1.0664

r=(1.0664-1)*100

which is equal to

=6.64%(Approx).
