    i am assuming simple interest as you havent mentioned anything now principal amount=P=4000 rate of interest per annum=R=? t=no. of years borrowed for=3 now he is paying an interest of "I'=total final amount-borrowed principal= 1900 now I=(P x R x t)/100 1900=(4000x R x 3)/100 solve, you should get the rate of interest per annum. multiply by 100 to get interest %age.

    Simple Interest formula: I = p r t <=> r = I/ p * t The difference amount between borrowed and paid back is the interest: I = $5,920 - $4,000 = $1,920 => Interest rate: r = 1,920 / 4,000 * 3 = .16 = 16%
