Answer :

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

∴ x and y ≥ 0

The tabular form of the given data in the question is

The profit on a package of screws A is Rs 7 and on package of screws B is Rs 10.

∴ the constraints are

4x+ 6y ≤ 240

And 6x + 3y ≤ 240 and x, y ≥ 0

And total profit is Z = 7x+ 10y

The mathematical formulation of the data is

Maximizing Z = 7x+ 10y

Subject to constraints

4x+ 6y ≤ 240

And 6x + 3y ≤ 240 and x, y ≥ 0

The feasible reason is determined by the system of constraints is:

The corner points are A(40, 0) , B( 30 , 20) , C ( 0 , 40)

The value of Z at these points is

The maximum value of Z is at point B(30, 20)

Therefore factory should produce 30 packages of screw A and 20 packages of screw B to get the maximum profit of Rs 410.
