    For the L.P. problem Min\[z=2x-10y\] subject to \[x-y\ge 0,\ \ x-5y\ge -5\] and \[x,\ y\ge 0\], \[z=\]

    A)                 ?10        

    B)                 ?20

    C)                 0             

    D)                 10

    Solution :

                    After drawing the graph, we get the minimum value of z at points (?5, 0), (0, 1) and (5/4, 5/4) and                  Min \[z=2(0)-10(1)=-10\].
