Abstract A cosmological model in which the universe has its critical density and gravitational constants generalized as coupling scalars in Einstein's theory is considered. A general method of solving the field equations is given. An exact solution for matter distribution in cosmological models satisfying G=G0(R/R0)n is presented. Corresponding physical interpretations of the cosmological solutions are also discussed.
