This paper addresses the problem of estimating a general parameter using information on an auxiliary variable X. We have suggested a class of exponential-type ratio estimators for the parameter and its properties are studied. It is identified that the estimators due to Upadhyaya etal. [Journal of Statistical Theory and Practice (2011), 5(2), 285-302] and Yadav and Kadilar [Revista Columbiana de Estadistica, (2013), 36(1), 145-152] are members of the proposed estimator. We have also shown that the suggested estimator is more efficient than the estimators of Upadhyaya etal. (2011) and Yadav and Kadilar (2013). Numerical illustration is provided in support of the present study.
