Here, Principal,P=10,800
Time,n=3 years
Rate,R=1212%=252%
Amount,A=P(1+R100)n
=10,800(1+25200)3
=10,800(225200)3
=10,800×225200×225200×225200
=108×2252×225200×225200
=54×2251×225200×225200
=27×2251×225100×225200
=13.5×2251×225100×225100
=13.5×225×225×225100×100
=13.5×2.25×2.25×225
A=Rs 15377.34
Compound Interest = Amount −P
=15377.34−10,800
=Rs 4577.34
