Answer 2

Given : Rs. 225 at an annual rate of 10% for 2 years and 6 months?

To Find : The compound interest  

A. 62.5

B. 60.86

C. 54.54

D. 60.60

Solution:

1st calculate amount after 2 years and interest in 2 years

P = 225

R = 10 %

n = 2

A = P(1 + R/100)ⁿ

A = 225(1 + 10/100)²

=> A = 272.25  Rs

Interest = 272.25 - 225  = 47.25  Rs

Now interest for next 6 months

P = 272.25

R = 10 %

n = 1/2  year = 6 months

Interest = 272.25 * 10 * (1/2)/100

= 13.6125  Rs

Total Interest = 47.25 +  13.6125 = 60.8625

Hence correct option is B)  60.86
