Solution

Corner points of the feasible region for an LPP are (0, 2), (3, 0), (6, 0), (6, 8) and (0, 5). Let F = 4x + 6y be the objective function. The Minimum value of F occurs at any point on the line segment joining the points (0, 2) and (3, 0).

Explanation:

Corner points Value of F = 4x + 6y  
(0, 2) Z = 4(0) + 6(2) = 12 ← Minimum
(3, 0) Z = 4(3) + 6(0) = 12 ← Minimum
(6, 0) Z = 4(6) + 6(0) = 24  
(6, 8) Z = 4(6) + 6(8) = 72 ← Maximum
(0, 5) Z = 4(0) + 6(5) = 30  

The minimum value of F occurs at any point on the line segment joining the points (0, 2) and (3, 0).
