The corner points of the feasible region determined by the system of linear constraints are $(0,0),(0,40),(20,40),(60,20),(60,0)$.The objective function is $Z=4x+3y.$ Compare the quantity in column A and column B: <br>$\begin{array}{1 1}column\; A &amp; column\; B\\maximum\;of \;z &325\end{array}$

Question

$$\begin{array}{1 1}(A)\;The\;quantity\; in\;column\;A\;is\;greater\\(B)\;The\;quantity\; in\;column\;B\;is\;greater\\(C)\;The\; two\; quantites\; are\; equal\\(D)\; The\; relationship\; cannot\; be \;determined\; on\; the\; basis\; of\; the\; information\; supplied\end{array}$$
