Answer: 22%
Explanation:
Compound interest at 20% per year for 2 years is;
= (1 + 20%)² - 1
= 1.44 - 1
= 44%
The simple interest in 2 years will also be 44% for it to be equivalent.
For the yearly simple interest rate simply divide by 2 because simple interest does not get compounded.
= 44%/2
= 22%
