Answer :

Let the factory manufactures x screws of type A and y screws of type B on each day.

 x≥0, y≥0

Given that:


The constraints are


4x + 6y ≤ 240


6x + 3y ≤ 240


Total profit: Z = 0.70x + y


Subject to,

2x + 3y ≤ 120


2x + y ≤ 120


x≥0, y≥0.

Now, plotting the equations 2x + 3y ≤ 120 and 2x + y ≤ 120 we get,

the common feasible region is OCBAO.



The maximum value of ‘Z’ is 41 at (30,20). Thus the factory showed produce 30 packages at screw A and 20 packages of screw B to get the maximum profit of Rs.41.
