Given :   You put Rs. 10,000 in a CD account for a locking period of one year at 6.7% rate p.a.

At the end of the locking period, you decide to reinvest the money in two more locking period of year each.

To Find :   What will be the amount at the end of third year

Solution:

Case 1 : Simple Interest

Amount after 1 Year = P + SI

SI  = P * R * T /100

P = 10000

R = 6.7

T = 1  

SI = 10000 * 6.7 * /100  =   670   Rs

Amount after 1 Year  = 10000 + 670 = 10670

10670 Reinvested

P = 10670

R = 6.7

T = 2 Years

SI =  10670 * 6.7  * 2 / 100  = 1,429.78  Rs

Amount at the end of 3rd year   =  10670 + 1,429.78  

= 12,099.78  Rs

Considering compound interest

P = 10000

R = 6.7

T = 3 years

A = 10000 ( 1 + 6.7/100)³ = 12,147.68  Rs
