The corner points of the feasible region determined by the system of linear constraints are $\displaystyle (0, 0)$, $\displaystyle (0, 40)$, $\displaystyle (20, 40)$ $\displaystyle (60, 20)$ and $\displaystyle (60, 0)$. If the objective function of an LPP is $\displaystyle \mathrm{Z}=4 \mathrm{x}+3 \mathrm{y}$, then the maximum value is :
