2 a. Explain the graphical method of solving Linear Programming Problem.

b. A paper mill produces two grades of paper viz., X and Y. Because of raw material
restrictions, it cannot produce 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 requires 0.20 and 0.40 hours
to produce 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.
