Conventional solutions of the (Mean) King's problem without using entanglement have been in-vestigated by P. K. Aravind, Z. Naturforsch. 58a, 682 (2003). We report that the upper bound for the success probability claimed is not valid in general but we give a condition for the claim to be justified.
