Question

Find the simple interest and the amount at simple interest in problems from $1$ through $4$ :
$Rs600$ for $5$ years at $12\frac{1}{2}\%p.a$

Answer 1

$P=600$
$R=12\frac{1}{2}$% $=\frac{25}{2}$%
$T=5$ yr.
$SI=\frac{PRT}{100}=\frac{600\times 25\times 2}{100\times 2}$
$375$
Amount=P+SI$=600+375$
$=Rs975$
