Vedclass · Answer

Here, $CI = P \left[\left(1+\frac{ R }{100}ight)^{3}-1ight]$

$\Rightarrow \quad 504.40= P \left[\left(1+\frac{5}{100}ight)^{3}-1ight]$

$\Rightarrow \quad 504.40= P \left[\left(\frac{21}{20}ight)^{3}-1ight] \Rightarrow 504.40= P \left[\frac{1261}{8000}ight]$

$\Rightarrow P ($ Principal $)= Rs .3200$

$\Rightarrow SI =\frac{ P 	imes R 	imes T }{100}=\frac{3200 	imes 5 	imes 3}{100}= Rs .480$
