(A) Let $q_1$ be the charge on the inner shell of radius $a$ and $q_2$ be the charge on the outer shell of radius $2a$.The potential at the surface of the inner shell is given by: $V_{inner} = \frac{kq_1}{a} + \frac{kq_2}{2a} = 10\,V$.The potential at the surface of the outer shell is given by: $V_{outer} = \frac{kq_1}{2a} + \frac{kq_2}{2a} = 5\,V$.The potential at the centre of the shells is given by: $V_{centre} = \frac{kq_1}{a} + \frac{kq_2}{2a}$.Comparing this expression with the equation for the potential at the inner shell,we can see that $V_{centre} = V_{inner} = 10\,V$.

If the electric potential of the inner shell of radius $a$ is $10\,V$ and that of the outer shell of radius $2a$ is $5\,V$,then the potential at the centre will be.....$V$
