\begin{gathered}As \: interest \: is \: compounded \:half\\yearly, \:so \: number \: of \:conversion \:periods\\in \: 1\frac{1}{2} \: years \: is \: 3, \:So, \: n = 3\end{gathered}

\begin{gathered}Compound \: interest = A - P \\= 70304 - 62500 \\= Rs\:7804\end{gathered}
Compoundinterest=A−P
=70304−62500
=Rs7804
Therefore.,
\red { Compound \: interest} \green {= Rs \:7804 }Compoundinterest=Rs7804
