Here we proposed Efficient Families of Chain Estimator for Ratio and Product of two population Means using known information on one of the variables of the given two auxiliary variables. The bias and the mean square error of proposed families are upto first order approximation. The optimum mean square errors are also obtained. The gain in efficiency is illustrated emperically.
