Principal Amount = P = 280,000
Final Amount = F = 386,400
Years = T = 4
Simple Interest = SI = F - P = 106,400
Rate = R

SI = P x R x T
R = SI/(P x T) = 106,400/(1,120,000)
= 0.095
= 9.5%

Use that to find the amount per year
Why we should find for percent the interest while we have asked to find the amount of interest please can you explain to me which word imply the required is percentage interest
Good question. The problem implies the same amount paid every year, so it'll be simple interest.

The total interest paid was 106400 over 4 years. Just divide that by 4 to get the annual interest paid.
