Graphic method can be applied to solve a LPP when there are only _____________ variable.
A.
One
B.
More than One
C.
Two
AnswerD.
Three
Answer: Option C
Solution
Answer: Option C
Solution:
Graphic method can be applied to solve a LPP when there are only two variable. This method is used to solve a two variable linear program. If you have only two decision variables, you should use the graphical method to find the optimal solution. A graphical method involves formulating a set of linear inequalities subject to the constraints. Then the inequalities are plotted on a X-Y plane.
