This paper deals with the problem of estimation of finite population mean in case of post-stratification. Following the approach of Srivenkataramana [16] and Bondyopadhyayh [2], we have proposed dual to separate ratio type exponential estimator. It has been shown that the proposed estimator is more efficient than usual unbiased estimator, usual dual to separate ratio type estimator and other estimators under certain given conditions. The bias and mean squared error of the proposed estimator is obtained up to the first degree of approximation. An empirical study has been carried out to demonstrate the performance of the suggested estimator.
