Answer:

$Required \: sum\\=Rs\:3000$

Step-by-step explanation:

$Let\: Principal = Rs P,\\Given \:simple\: interest (I)=Rs\:450\\Time(T)=3\: years\\Rate\:of\: interest (R)=5\% \:p.a$

$We\:know \:that\\\boxed {P=\frac{100\times I}{TR}}$

$\implies P=\frac{100\times 450}{3\times 5}\\=Rs\:3000$

Therefore,

$Required \: sum\\=Principal\\=Rs\:3000$
