If the corner points of the feasible region for an LPP are (60, 0), (120, 0), (60, 30) and (40, 20), then the maximum value of the objective function Z = 5x + 10y occurs at:

(120, 0) only (60, 0) only (60, 30) only every point on the line segment joining the points (120, 0) and (60, 30)

every point on the line segment joining the points (120, 0) and (60, 30)

The correct answer is Option (4) → every point on the line segment joining the points (120, 0) and (60, 30)
