Refer to Exercise 27. (Maximum value of Z + Minimum value of Z) is equal to
Correct Answer D)
Answer:
Value of Z = 3x – 4y, at corner points are –
At (0, 0) = 0
At (0, 8) = -32
At (4, 10) = -28
At (6, 8) = -14
At (6, 5) = -2
At (5, 0) = 15
So, clearly maximum value is at (5, 0)
Maximum value = 15,
Minimum value = -32
So, maximum + minimum = 15 -32
= -17
