Question

What will be the ratio of simple interest earned by certain amount at the same rate of interest for $6$ years and that for $4$ years?

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

Answer 1

The correct option is D $3:2$

Let the principal for both the case be Rs. $P$ and the rate of interest be $R\%$ p.a.

Then, required ratio $=\frac{P\times R\times 6}{100}:\frac{P\times R\times 4}{100}=6:4=3:2$.
