Question

What will be the ratio of simple interest earned by a certain amount at the same rate of interest for 6 years and 9 years?

• A. 1 : 3
• B. 1 : 4
• C. 2 : 3
• D. Data inadequate

Answer 1

Answer: (C)

2 : 3

Answer 2

Ratio of simple interest earned by a certain amount at the same rate of interest for 6 years and 9 years is

$\frac{P_1×R_1×t_1}{100}:\frac{P_2×R_2×t_2}{100}$

Where, P1 and P2 = P ; R1 and R2 = R (as the principle and rate of interest for both the cases are same)

$t1=6;t2=9$
$\frac{P×R×6}{100}:\frac{P×R×9}{100}$

$6:9(or)2:3$

Hence, option C is the correct answer.The correct option is (C): 2 : 3
