With respect to the following shaded feasible region (ABCDEFA), the maximum value of the objective function $z=3x+4y-2$ is at point(s):
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Point E only
Objective function: $z = 3x + 4y - 2$
At $E(2,5)$: $z = 3*2 + 4*5 - 2 = 6 + 20 - 2 = 24$
Answer: $z = 24$, which gives the maximum value.
