(c) We have, $C I-S I=P\left[\left(\frac{R}{100}ight)^{3}+3\left(\frac{R}{100}ight)^{2}ight]$

$\Rightarrow \quad 27.27=P\left[\left(\frac{3}{100}ight)^{3}+3\left(\frac{3}{100}ight)^{2}ight]$

$=P\left[\frac{27+2700}{100 	imes 100 	imes 100}ight]$

$\Rightarrow P=\frac{27.27 	imes 100 	imes 100 	imes 100}{2727}$

$=₹ 10000$
