Answer:

i= 0.2098 = 20.98%

Explanation:

Giving the following information:

Monthly rate (i)= 1.60% = 0.016

Number of periods (n)= 12 months

To calculate the annual real interest rate, we need to use the following formula:

i= [(1+i)^n] - 1

i= [(1 + 0.016)^12] - 1

i= 1.2098 - 1

i= 0.2098 = 20.98%
