Abstract : In M/G/1 retrial queueing system with two types of customers and feedback, we derived the joint generating function of the number of customers in two groups by using the supplementary variable method. It is shown that our results are consistent with those already known in the literature when $\delta_k=0(k=1,2),\lambda_1=0$\\ ~ or ~ $ \lambda_2 = 0$.
