Coherent Potential Approximation (CPA) for a n-component liquid alloy is derived by taking the limit of a generalized lattice-gas model, criminally formulated by Yonezawa and Watabe. We have taken the transfer integral tAB between atoms A and B as the geometrical mean of tAA and tBB. In the absence of short range order, our results are consistent with that obtained by Shiba using a coherent locator method.
