In article [14], an algebraicity result, an extension of Mahnkopf's result [10], for the critical values of L-functions for GL(3) x GL(1) over a totally real number field was proved. In this paper, we again prove an extension of Mahnkopf [101, for all the critical values of certain Rankin Selberg L-functions attached to a pair of algebraic automorphic representations on GL(3) x GL(1) over a CM field, having cohomology with a general coefficient system.
