In this paper, we prove a general approximation theorem useful in obtaining order of convergence estimates for the approximation of the solutions of a class of variational inequalities. The theorem is then applied to obtain an optimal rate of convergence for the approximation of a second-order elliptic problem with convex set K = (v <EHQ(il): v > X a.e. in il).
