a. Describe linear programming problem? Elucidate the steps involved in the linear programming problem formulation?
b. A paper mill manufactures two grades of paper viz., X and Y. Due to raw material restrictions, it can’t manufacture more than 400 tons of grade X paper and 300 tons of grade Y paper in a week. There are 160 production hours in a week. It needs 0.20 and 0.40 hours to manufacture a ton of grade X and Y papers.
The mill earns a profit of Rs. 200 and Rs. 500 per ton of grade X and Y paper respectively. Formulate this as a Linear Programming Problem.
