Amount of money=?

Solution:-

$amount =p( {1 + \frac{ \frac{r}{2} }{100} ) }^{2n} \\ \\ amount = 5000( {1 + \frac{2.5}{100}) }^{2 \times 2} \\ \\ amount = 5000 \times {1.025}^{4} \\ \\ amount = rs.5519.064 \\ \\ interest = amount - principal \\ \\ interest = 5519.064 - 5000 \\ \\ interest = rs.519.064$
