The feasible region (shaded) for a LPP is shown in the following figure. Then the maximum value of \(z = 11x+7y\) is:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 47
The shaded region is bounded by the axes and the lines x = 3 and y = 2. Its corner points are O(0, 0), A(3, 0), B(3, 2) and C(0, 2).
The maximum of z occurs at a corner point:
\(z(0, 0) = 0\)
\(z(3, 0) = 33\)
\(z(3, 2) = 33 + 14 = 47\)
\(z(0, 2) = 14\)
So the maximum value of z is 47, at B(3, 2).
