In this paper, we obtain new exact solutions and first-order late-time solutions for the generalized Chaplygin gas Ho. rava-Lifshitz quantum cosmology with the equation-of-state p = -A(-alpha). Based on the Schutz formalism, we use the matter degree of freedom to recover the notion of time in quantum domain. This enables us to study time evolution of wave functions (wave packets) as well as their corresponding classical solutions. In particular, for a = 0, we obtain new exact classical and quantum mechanical solutions for various gravitational cases which are valid for both early and late times. For alpha = 1/3 and a = 1 (the standard Chaplygin gas), and up to the first-order approximation, we solve the corresponding Schrodinger-Wheeler-DeWitt equation and find the late-time solutions in the classical and quantum domains. Also, we study the accelerating behavior of solutions at the late times and we compare the results with solutions raised from general relativity.
