Note: After learning how to formulate an LPP for this managerial problem, you can also learn the solution of the formulated LPP through Graphical Method by watching the lecture "LPP Graphical Method - 11'
A steel company has two iron mines having different production capacity. The raw iron is classified into three categories High, Medium/Fair and Low according to the quality. The factory of the company requires at least 12 tons of High-grade iron, at least 8 tons of Medium/Fair-grade iron and at least 24 tons of Low-grade iron per week. The daily expenditure of the first mine is ` 20,000 and that of the second mine is ` 16,000. The daily production of raw iron in the two mines is as follows:
Mine Daily production (in tons)
High Medium/Fair Low
I 6 2 4
II 2 2 12
To minimize the cost of transportation, for how many days each mine should work in a week? Formulate this as an LPP (DO NOT SOLVE IT).
