Answer:
Let
number of packages of screws A produced = x
and
number of packages of screws B produced = y
The
number of minutes for producing 1 unit of each item is given below.
Therefore,
the above L.P.P. is given as
Maximize,
P = 7x + 10y subject to the constaints.
4x
+ 6y 240; 6x + 3y 240
i.e.
2x + 3y 120; 2x + y 80, x, y 0
L1
: 2x + 3y + 120 L2 : 2x + y + 80
Here
profit is maximum at E (30, 20)
Number of
packages of screws A = 30
Number
of packages of screws B = 20
Maximum
profit = Rs.410
