For a certain sum, the simple interest in 2 yr at 8% per annum is RS. 110 more than the simple interest in 1 yr at the rate of 5% per annum for the same sum. Find the sum.

A) RS.5000
B) RS.1000
C) RS.1050
D) RS.950

Correct Answer:


B) RS.1000

Description for Correct answer:
Given, \( \Large SI_{1}-SI_{2} \) = 110, \( \Large T_{1} \) = 2 yr,

\( \Large T_{2} \)=1yr, \( \Large R_{1} \)=8%, \( \Large R_{2} \)=5%

According to the question,

\( \Large \frac{P\times 8\times 2}{100}-\frac{P\times 5\times 1}{100} \)=110

=> \( \Large \frac{11P}{100} \)=110

P= RS.1000
