Answer :

A. The quantity in column A is greater


Z = 4x + 3y


Corner points- (0, 0), (0, 40), (20, 40), (60, 20), (60, 0)


As feasible region is bounded.


Value of Z at corner points-


At (0, 0), Z = 0


At (0, 40), Z = 120


At (20, 40), Z = 200


At (60, 20), Z = 360


At (60, 0), Z = 240


Clearly, maximum value of Z is 360, which is greater than 325.
