If the ratio of the sum invested and simple interest received after 1 year is 20:11 respectively, then find the rate of interest.
Let the sum invested and simple interest received be Rs.20x and Rs.11x respectively. Let the rate of investment be r% p.a. Therefore, {(20x x 1 x r)/100} = 11x => r = 55%
