The corner points of the feasible region determined by the system of linear constraints are (0,3), (1, 1) and (3, 0). Let Z=px+qy, where p, q>0, be the objective function. Then the condition on p and q so that the minimum of Z occurs at (3, 0) and (1, 1) is:

Which of the following sets is not convex?

The number of Basic variables in any solution of Transportation problem with m-origins and n-destinations is

In a LLP degeneracy arises at

For the objective function z = px + qy, where p, q > 0 the corner points of the feasible region determined by the system of linear constraints are - (0, 10), (5, 5), (15, 15) and (0, 20), condition on p and q so that maximum of z occurs at both the points (15, 15) and (0, 20) is:
