Calculate the complex power delivered to a factory that includes two loads with the following specifications:

\[
\begin{gathered}
\text { Inductive Load : } P_{1}=60 \mathrm{~kW}, Q_{1}=660 \mathrm{kVAr} \\
\text { Capacitive Load : } P_{2}=240 \mathrm{~kW}, P F=0.8
\end{gathered}
\]

1) \((180+j 840) \mathrm{kVA}\)

2) \((300+j 480) k V A\)

3) \((300+j 840) \mathrm{kVA}\)

4) \((180+j 480) \mathrm{kVA}\)
