A. 20%
B. 25%
C. 30%
D. 10%
E. None of them

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

In 5 years, capital will be 200 tk

so, the interest = (200 - 100) = 100tk

we know, i = pnr

or, r = i/pn

or, r = 100/(100*5)

∴r = 1/5

the rae of simple interest = 1/5 * 100% = 20%

ans: 20%
