Answer: 11.65%

Explanation:

The $13,241.39 is a future value amount as it is what is to be accumulated in 2 years.

Future value formula therefore applies:

Future value = Current value * ( 1 + interest rate) ^ no. of years

13,241.39 = 10,621.36 * ( 1 + i) ²

(1 + i)² = 13,241.39 / 10,621.36

(1 + i)² = 1.24667556697

1 + i = √1.24667556697

i = 1.116546267 - 1

i = 11.65%
