Maximize and Minimize `Z = 5x + 10y`, subject to constraints are
` x + 2y le 120 , x + y ge 60, x - 2y ge 0 " and " x, y ge 0`.

Text Solution

Verified by Experts

The correct Answer is:
The minimum value of Z is 300 at (60,0) and the maximum value of Z is 600 at all the points on the line segment joining the points (120,0) and (60,30).
