Question

What is the ratio of simple interest earned on certain amount at the rate of 12% for 6 years and that for 12 years?

• A. 1 : 2
• B. 2 : 3
• C. 3 : 4
• D. 4 : 5

Answer 1

Answer:

A. 1 : 2

Let Rs. p be the principal amount

Simple interest for 6 years $=\frac{(P\times{12}\times{6})}{100}$

Simple interest for 12 years $=\frac{(P\times{12}\times{12})}{100}$

∴ Required ratio $=\frac{(P\times{12}\times{6})}{100}$:$\frac{(P\times{12}\times{12})}{100}$

= 6 : 12

= 1 : 2
