Correct Answer: 2 : 5


Solution : Principal = P for both cases
Rate = R for both cases
Time = 8 years for 1st case, 20 years for 2nd case.
Now,
Simple interest for 1st case : Simple interest for 2nd case
= $\frac{\text{Principal × Rate × Time}}{100}$ : $\frac{\text{Principal × Rate × Time}}{100}$
= $\frac{\text{P × R × 8}}{100}$ : $\frac{\text{P × R × 20}}{100}$
= $8 : 20$
= $2 : 5$
Hence, the correct answer is 2 : 5.
