The simple interest for certain sum in 2 yr at 4% pa is RS. 80. What will be the compound interest for the same sum, if conditions of rate and time period are same?

A) RS.91.60
B) RS.81.60
C) RS.71.60
D) RS.80

Correct Answer:


B) RS.81.60

Description for Correct answer:
Given, n = 2 yr, R = 4% and SI = 80

According to the formula,

CI = \( \Large SI \left(1+ \frac{R}{100}\right) \)

= \( \Large 80 \left(1+ \frac{4}{200}\right) \)=\( \Large \frac{80\times 51}{50} \)=RS.81.60
