CUET Mathematics - Let the corner points of the bounded feasible region of the linear programming problem (LPP) Z = ax+by be: (0, 0), (2, 0), (20/19, 45/19) and (0, 3). If the optimal value of Z occurs at both points (2, 0) and (20/19, 45/19), then the relation between a and b is: | PYQs + Solutions | AfterBoards
