Question

18. For maximization LPP, the objective function coefficient for an artificial variable is
(b)-M,
(a) +M
(c) +1,
(d) zero.​

Answer 1

Answer:

+M is the right answer for this question

Answer 2

The correct option is "b"

Maximization of objective function in an LP model means Value occurs at allowable set of decisions. The amount by which the objective function value would change when one unit of a decision variable is altered, is given by the corresponding objective function coefficient.

Here the answer is -M

Hence for maximization LPP, the objective function coefficient for an artificial variable is -M
