Question

At what rate per cent per annum will $Rs.3600$ amount to $Rs.4734$ in $3\frac{1}{2}$ years?

Answer 1

$P=Rs.3600$, $A=Rs.4734$ ,$T=3\frac{1}{2}=\frac{7}{2}$ years

$S.I.=A-P$

$=4734-3600$

$=Rs.1134$

$R=\frac{S.I.\times 100}{P\times T}$

$=\frac{1134\times 100\times 2}{3600\times 7}$

$=9\%$
