$ \frac{1}{C_{e q}} =\frac{1}{8}+\frac{1}{24}+\frac{1}{12} $
$\Rightarrow C_{e q} =4\, \mu F$
$ V_{A}-V_{B} =60 \mathrm{\,V}$
$\mathrm{q}=\mathrm{C}_{\mathrm{eq}}\left(\mathrm{V}_{\mathrm{A}}-\mathrm{V}_{\mathrm{B}}\right)=240\, \mu \mathrm{C}$
Charge on $5 \mu \mathrm{F}$ Capacitor $=\frac{240}{24} \times 5=50\, \mu \mathrm{C}$
