(c) Let the principal be $₹ P$. Then, $CI =P\left[\left(1+\frac{R}{100}ight)^{2}-1ight]$

$\Rightarrow \quad 328=P\left[\left(1+\frac{5}{100}ight)^{2}-1ight]=P\left[\left(\frac{21}{20}ight)^{2}-1ight]$

$\Rightarrow \quad 328=P\left(\frac{441}{400}-1ight)=P\left(\frac{441-400}{400}ight)=P\left(\frac{41}{400}ight)$

$\Rightarrow P=\frac{328 	imes 400}{41}=3200$
