O1. A retail store stocks three types of shirts X,Y and Z. These are packed in attractive cardboard boxes. During a week the store can sell a maximum of 350 shirts of type X and a maximum of 200 shirts of type Y and Z. The storage capacity, however, is limited to a maximum of 450 of all types combined. Type X shirt fetches a profit of Rs. 3/- per unit, type Y a profit of Rs. 4/- per unit, and type Z a profit of Rs. 2/- per unit. How many of each type the store should stock per week to maximize the total profit? Formulate a mathematical model of the problem. Q2. Considering the following problem: MaximizeZ=subjectto:50x1+80x2x1+x2205x1+2x260x110x1,x20 1. Trace the constraints in the Coordinate Axes 2. Locate the Feasible Solution Area 3.
