An oil company requires 12,000, 20,000 and 15,000 barrels of high-grade, medium grade and low grade oil, respectively. Refinery A produces 100, 300 and 200 barrels per day of high grade, medium grade and low grade, respectively, while refinery B produces 200,400 and 100 barrels per day of high-grade, medium grade and low grade, respectively. If refinery A costs Rs 400 per day and refinery B costs Rs 300 per day to operate, how many days should each be run to minimize costs while satisfying requirements.

A oil company requires 12000, 20000 and 15000 barrels of high grade, medium grade and low grade oil respectively. Refinery A produces 100, 300 and 200 barrels per day of high, medium and low grade oil respectively whereas the refinery B produces 200, 400 and 100 barrels per day respectively. If A costs 400 per day and B cost 300 per day to operate. To find how many days should each be run to minimize the cost of requirement, formulate this as a L.P.P.

A rubber company is engaged in producing three types of tyres A, B and C. each type requires processing in two plants, Plant I and Plant II.
