1.	The corner points of the feasible region determined by the system of linear constraints are (0,10), (5,5), (15,15), (0,20). Let z=px+qy where p,q>0. Condition on p and q so that the maximum of z occurs at both the points (15,15) and (0,20) is
Answer» The corner points of the feasible region determined by the system of linear constraints are $(0, 10), (5, 5), (15, 15), (0, 20) .$ Let $z = p x + q y$ where $p, q > 0.$ Condition on $p$ and $q$ so that the maximum of $z$ occurs at both the points $(15, 15)$ and $(0, 20)$ is
