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