Time is directly proportional to the simple interest. Hence the ratio would be:= 6:9
Let the amount be P.
Let the rate of interest be r.
Simple interest for 6years= (Pxrx6)/100
Simple interest for 9 years= (Pxrx9)/100
According to the question: Simple interest for 6 years/Simple Interest for 9 years= ((Pxrx6)/100)/((Pxrx9)/100)=6/9=6:9
