What will the ratio of simple interest earned by certain amount at the same rate of interest for 6 years and that for 9 years.
Answer with explanationAnswer: Option D
We know that,
SI = Pnr/100
Let the principal be P and rate of interest be R
SI = [P*6*R/100] / [P*9*R/100]
SI = 6/9 = 2/3
SI = 2 : 3
