In this note, we prove a family of sharp weighed inequality which involves weighted $k$-th mean curvature integral and two distinct quermassintegrals for closed hypersurfaces in $\mathbb{ R}^n$. This inequality generalizes the corresponding result of Wei and Zhou \cite{ WZ} where their proof is based on earlier results of Kwong-Miao \cite{ KM1,KM2}. Here we present a proof which does not rely on Kwong-Miao's results.
