Let x and y be number of bottles of medicines A and B be prepared.
∴According to the question,
x + y ≤ 45000 , 3x + y ≤ 66000, x ≤ 20000, y ≤ 40000, x ≥ 0, y ≥ 0
Maximize Z = 8x + 7y
The feasible region determined by x + y ≤ 45000 , 3x + y ≤ 66000, x ≤ 20000, y ≤ 40000, x ≥ 0, y ≥ 0 is given by
The corner points of feasible region are A(0,0) , B(0,40000) ,C(5000,40000),D(10500,34500),E(20000,6000),F(20000,0).
The value of Z at corner points are
Corner Point |
Z = 8x + 7y |
|
A(0, 0) |
0 |
|
B(0, 40000) |
280000 |
|
C(5000, 40000) |
320000 |
|
D(10500, 34500) |
325500 |
Maximum |
E(20000, 6000) |
202000 |
|
F(20000, 0) |
160000 |
|
The maximum value of Z is 325500 at point (10500,34500).
Hence, the manufacturer should produce 10500 bottles of medicine A and 34500 bottles of medicine B.
