Question:

If the corner points of the bounded feasible region of an LPP are (0, 2), (3, 0), (6, 0), (6, 8) and (0, 5), then the minimum value of objective function $F= 4x + 6y$ occurs at

Options:

(0, 2) only

(3, 0) only

the mid point of the line segment joining (0, 2) and (3, 0)

every point on the line segment joining (0, 2) and (3, 0)

Correct Answer:

every point on the line segment joining (0, 2) and (3, 0)

Explanation:

The correct answer is Option (4) → every point on the line segment joining (0, 2) and (3, 0)

Objective function: $F = 4x + 6y$

Corner points:

(0, 2): F = 4*0 + 6*2 = 12

(3, 0): F = 4*3 + 6*0 = 12

(6, 0): F = 4*6 + 6*0 = 24

(6, 8): F = 4*6 + 6*8 = 24 + 48 = 72

(0, 5): F = 4*0 + 6*5 = 30

The minimum value F = 12 occurs at (0, 2) and (3, 0).

Since the objective function is linear, all points on the line segment joining (0, 2) and (3, 0) will also give F = 12.
