Q46,paper3,j 12. The feasible region represented by the constraints x 1 – x 2 < =1, x 1 + x 2 >= 3, x 1 >= 0, x 2 >= 0 of the objective function Max Z = 3 x 1 + 2 x 2 is

options (A) A polygon
(B) Unbounded feasible region
(C) A point
(D) None of these
Answer(B) Unbounded feasible region. Explanation. Draw the graph x2=x1-1
and x2=3-x1.
and other conditions are x1>=0 and x2>=0. it forms unbounded feasible region.
