Question
Solve the linear programming problem and determine the maximum profit to the manufacturer.

Answer

We have Maximise Z = 100x + 170y Subject to
$3\text{x}+2\text{y}\leq3600,\text{x}+4\text{y}\leq1800,\text{x}\geq0,\text{y}\geq0$
From the shaded feasible region it is clear that the coordinates of corner points are (0, 0), (1200, 0), (1080, 180) and (0, 450).
On solving x + 4y = 1800 and 3x + 2y = 3600, we get x = 1080 and y = 180.
Corner points
Corresponding value of Z = 100x + 170y
(0, 0)
(1200, 0)
(1080, 180)
(0, 450)
0
1200 ×100 = 12000
100 × 1080 + 170 × 180 = 138600 (maximum)
0 + 170 × 450 = 76500
 Hence, the maximum profit to the manufacture is 138600.

A diet is to contain at least $80$ units of vitamin $A$ and $100$ units of minerals. Two foods $F_1$ and $F_2$ are available. Food $F_1$ costs $Rs. 4$ per unit and $F_2$ costs $Rs. 6$ per unit one unit of food $F_1$ contains $3$ units of vitamin $A$ and $4$ units of minerals. One unit of food $F_2$ contains $6$ units of vitamin $A$ and $3$ units of minerals. Formulate this as a linear programming problem and find graphically the minimum cost for diet that consists of mixture of these foods and also meets the mineral nutritional requirements.
