Answer
The concentration of $Ca^{2+}$ in the solution will increase.
Work Step by Step
As we discussed in 59a, the equilibrium will move to increase the consume of the added $Ca^{2+}$, and it will produce more $CaF_2(s)$. That follows the Le Chatelier's principle.
But, that adjustment is not capable of consuming all of the added $Ca^{2+}$, which means that, the added concentration is higher than the consumed.
Therefore, the concentration of $Ca^{2+}$ will increased.
