Explanation
Object function of LPP is
Let the number of goods of type A and B produced be respectively x and y.
To maximize, Z=(100x+120y)
Subject to the constraints:
2x+3y≤30 ---- (1)
3x+y≤17---- (2) where x,y≤0.
Take the testing points as (0,0) for (1) we have: 2(0)+3(0)≤30⇒0≤30, which is true.
Take the testing points as (0,0) for (2) we have: 3(0)+(0)≤17⇒0≤17, which is true.
The shaded region OACBO as shown in the given figure is the feasible region, which is bounded.
The coordinates of the corner points of the feasible region are A(173,0),E(3,8),C(0,10)andO(0,0).
So, Value of Z at A(173,0)=17003
Value of Z at B(0,10)=1200
Value of Z at C(3,8)=1260
Value of Z at O(0,0)=0
The maximum value of Z is Rs.1260 which occurs at x=3 and y=8.
Thus the factory must produce 3 units and 8 units of the goods of type A and B respectively. The maximum obtained profit earned by the factory by producing these items is Rs.1260.
Yes, we agree with the view of manufacturer that men and women workers are equally efficient and so should be paid at the same rate.
