In this paper following , we propose a modified ratio-product type exponential estimator to estimate the finite population meanȲ of the study variable y in presence of non-response in different situations viz. (i) population meanX is known, and (ii) population meanX is unknown. The expressions of biases and mean squared error of the proposed estimators have been obtained under large sample approximation using single as well as double sampling. Some realistic conditions have been obtained under which the proposed estimator is more efficient than usual unbiased estimators, ratio estimators, product estimators and exponential ratio and product estimators reported by Rao (1986) and are found to be more efficient in many situations.
