Question

In the graphical solution of a linear programming problem to minimize cost, we seek to move the example line for the objective function

1. Away from the origin

2. Toward the origin

3. Parallel to the X1 axis

4. Parallel to the X2 axis

5. None of the above

Answer 1

Away from the origin

(To Minimize the objective function, we take the equation of constraints of greater than type (e.g. The comtraint maybe 2x + 3y >=4.

We solve the equations graphically and give the outside area from the points at which the equations of constraints are solved. We find out the objective function such that Z objective function will have a certain mimnum value, that is Z is greater than or equal to some value, thus we seek to move example line for objective function away from origin)
