Question:
The corner points of the feasible region in graphical representation of a L.P.P. are \((2, 72)\), \((15, 20)\) and \((40, 15)\). If \(Z = 18x + 9y\) be the objective function, then
- A. \(Z\) is maximum at \((2, 72)\), minimum at \((15, 20)\)
- B. \(Z\) is maximum at \((15, 20)\), minimum at \((40, 15)\)
- C. \(Z\) is maximum at \((40, 15)\), minimum at \((15, 20)\)
- D. \(Z\) is maximum at \((40, 15)\), minimum at \((2, 72)\)
