What will be the ratio of simple interest earned by certain amount at the same rate of interest for 2 years and that for 8 years?  Choose the correct choice from the following choices:
A) 3 : 2
B) 1 : 3
C) 2 : 3
D) 3 : 1
E) 1 : 4
1 : 4xplanation :   Simple Interest = PRT/100   Here Principal(P) and Rate of Interest (R) are constants   Hence, Simple Interest ∝ T   Required Ratio = Simple Interest for 2 years/Simple Interest for 8 years   =T1/T2   =2/8   =1/4   =1:4   Answer : Option 1 : 4
