Question 2 Feasible region (shaded) for a LPP is shown in the Fig. 12.6. Minimum of Z = 4x + 3y occurs at the point (A) (0, 8) (B) (2, 5) (C) (4, 3) (D) (9, 0) Corners points are (0, 8), (2, 5), (4, 3) and (9, 0) We need to Minimise Z = 4x + 3y Checking value of Z at all corner points Since the feasible region is unbounded, Hence, 23 may or may not be the minimum value of Z So, we need to graph inequality : Z < 23 4x + 3y < 23 As, there is no common points between the feasible region and the inequality. ∴ Min Z = 23 at (2, 5) So, the correct answer is (B)
