A subgroup $H$ is said to be
$nc$-supplemented in a group $G$ if there exists a subgroup $Kleq G$
such that $HKlhd G$ and $Hcap K$ is contained in $H_{G}$, the core
of $H$ in $G$. We characterize the supersolubility of finite groups $G$
with that every maximal subgroup of the Sylow subgroups is $nc$-supplemented in $G$.
