Answer:
c) 18.45%
Explanation:
The RATE formula is applied which is shown in the attachment.
The NPER reflects the time period.
Mentioned that,
Present value = $1
Future value or Face value = $3
PMT = $0
NPER = 6 years × 12 months = 72 months
The formula is shown below:
= Rate(NPER;PMT;-PV;FV;type)
The present value come in negative
So, the nominal interest rate is
= 1.54% × 12 months
= 18.48% approx
