Two nproducts A and B are to be manufactured by a firm. Each of these product has to be processed on two machines M1 and M2. Product A requires 4 hours on machine M1 and 5 hours on machine M2. Product B requires 5 hours on machine M1 and 2 hours on machine M2. The available capacity per month is 100 hours and 80hour for machine M1 and M2 respectively. The profit per unit is Rs.10 and Rs.5 on product A and B resespectively. Estimate the number of units of each type to be produced per month for maximum profit by simplex Method.
