Accepted Answer

The circuit can be drawn as shown
Each capacitor has capacitance of $5 \mu \mathrm{F}$.
The capacitors are in parallel. Hence equivalent capacitance
$\mathrm{C}=20 \mu \mathrm{F}$
The charge stored by the combination
$\mathrm{Q}=\mathrm{CV}=20 	imes 15=300 \mu \mathrm{C}$
$	herefore$ The charge on each capacitor is
$\frac{300}{4}=75 \mu \mathrm{C}$
