Following Agrawal and Sthapit [1], we have developed systems of exponential ratio-based and exponential product-based estimators. The proposed exponential ratio-based estimator of order and the proposed exponential product-based estimator of order are, under practical conditions, found to be more efficient than the customary exponential ratio and the mean per unit estimator and the customary exponential product estimator and the mean per unit estimator, respectively, when is optimally chosen.

With a view to establishing the supremacy of the proposed estimators over the existing estimators, numerical illustrations in respect of real populations have been considered.
