এখানে, সুদ $(I)=?$ টাকা, আসল $(P)=1000$ টাকা, সময় $(n)=6$ বছর, সুদের হার $(r)=6.5\%$ বা $\frac{65}{10}\%$ বা $\frac{13}{2}\%$

আমরা জানি, $I=Pnr \times \frac{1}{100}$

বা, $I=1000 \times \frac{13}{2} \times 6 \times \frac{1}{100}$

বা, $I=10\bcancel{00}\times\frac{13}{\cancel2}\times\overset3{\cancel6}\times\frac1{1\bcancel{00}}$

$\therefore I=390$

সুতরাং সুদাসল = সুদ+আসল = $390+1000$ = $1390$
