SUMMARY. In this paper a class of chain ratio type estimators has been developed for estimating population mean of the study variable using factor-type estimator (FTE) when the information on another auxiliary character is available along with the main auxiliary character. The optimum property of the suggested strategy has been studied. Theoretical and empirical studies have been done to demonstrate the efficiency of the suggested strategy with respect to the strategies which utilize the information on one and two auxiliary characteristics.
