A firm makes two products A and B has a total production capacity of 9 tonnes per day , with A and B utilising the same production facilities . The firm has a permanent contract to supply at least 2 tonnes of A per day to another company. Each tonne of A requires 20 machine hours of production time and each tonne of B required 50 machine hours of production time . The daily maximum possible number of machine hours is 360 . All the firm's output can be sold and the profit made is Rs. 80 per tonne of A and Rs. 120 per tonne of B . Formulate the problem of maximizing the profit as an LPP and solve it graphically
Let the product A be x and product B be y. Therefore we have :
Each tonne of A requires 20 machines hours of production time and each tonne of B requires 50 machine hours of production time. The daily maximum possible number of machine hours is 360, thus
All the firm's output can be sold and the profit made is 80$ per tonne of A and 120$ per tonne of B. Thus,
Max
Solving for x and y we get and
Thus,
Graphically it can be solved as :
