Question

An oil company requires 13000 ,20000and 15000 barrels of hi grade, medium grade and low grade oil respectively refinery a produces 100, three hundred and 200 barrels per day of high grade medium grade and low grade oil respectively where is the refinery be producers 200-400 and 100 barrels per day respectively if a cost rs 100 per day and b cost rs 300 per day to operate, how many days should eat be done to minimise the cost of requirement

Answer 1

Solution :-

Sulposerfineries A and B should run for x and y days respectively to minimise the total cost

The mathematical form of the given LPP is.

minimise z = 400x+300y

subject to constraints

100x+300y 1 \geqslant 3000 ---------(1)

300x+400y \geqslant 20000 --------(2)

200x+100y \geqslant 15000 ----------(3)

x \geqslant
