Suppose each capacitor has a maximum voltage of V.
If you wire them in parallel, the capacitance will be 10C and the energy stored will be 1/2 * 10C * V^2 = 5CV^2
If you wire them in series, the capacitance will be C/10 and the energy stored will be 1/2 * C/10 * 100V^2 or … 5CV^2
So there are many ways to do it and it all works out the same. The question is unanswerable.
