Basic Properties of Electric Charge

Two metallic spheres $A$ and $B$ of equal size each having charge $+12 \mathrm{\mu C}$ and a third sphere $C$ of different size carries charge of $-11 \mathrm{\mu C}$. What will be the charge of sphere $C$, if each of sphere $A$ and $B$ carries charge of $+3 \mathrm{\mu C}$ after making contact between three spheres?
