A company produces three products, X, Y, and Z. Each unit of Product X requires 2 hours of labor, 1 hour of machine time, and 3 hours of assembly time. Each unit of Product Y requires 1 hour of labor, 2 hours of machine time, and 2 hours of assembly time. Each unit of Product Z requires 3 hours of labor, 2 hours of machine time, and 1 hour of assembly time. The company has the following resources available: 200 hours of labor, 150 hours of machine time, 120 hours of assembly time The profit per unit for each product is as follows: Product X: Rs. 30/-, Product Y: Rs. 25/-, Product Z: Rs. 20/-. The company wants to maximize its total profit. d) The final simplex table for the above problem is given below. Note: s1, s2and s3 relates to products X, Y, and Z respectively.
