Question

Find the amount and the C.I. on Rs. 12000 at 10% per annum compounded half-yearly.

Answer 1

Principal(P)=Rs. 12000
Rate(r) =10%
Time(t)= 1 years
Amount= $=P\times {(1+\frac{r}{2\times 100})}^{n+2}$
$=Rs.12000\times {(1+\frac{10}{200})}^2$
$=Rs.12000\times {\left(\frac{210}{200}\right)}^2$
=Rs. $12000\times \frac{21}{20}\times \frac{21}{20}=Rs.13230$
C.I.= Amount-Principal
=Rs. 13230 -Rs. 12000=Rs. 1230
