A company manufactures two types of sweaters: type A and type B. It costs Rs 360 to make a type A sweater and Rs 120 to make a type B sweater. The company
can make at most 300 sweaters and spend at most Rs 72000 a day. The number of sweaters of type B cannot exceed the number of sweaters of type A by more
than 100. The company makes a profit of Rs 200 for each sweater of type A and Rs 120 for every sweater of type B.
Formulate this problem as a LPP to maximize the profit to the company.
Let’s assume x and y to be the number of sweaters of type A and type B respectively.
From the question, the following constraints are:
360x + 120y ≤ 72000 ⇒ 3x + y ≤ 600 … (i)
x + y ≤ 300 … (ii)
x + 100 ≥ y ⇒ y ≤ x + 100 … (iii)
Profit: Z = 200x + 120y
Therefore, the required LPP to maximize the profit is
Maximize Z = 200x + 120y subject to constrains
3x + y ≤ 600, x + y ≤ 300, y ≤ x + 100, x ≥ 0, y ≥ 0.
