Question
A wealthy farmer owns fifty acres of land. He is going to plant each acre with sugarcane or corn. Each acre planted with sugarcane yields Rs 16,000 profit; each with corn yields Rs 8,000 profit.
Labor (workers): sugarcane=5 corn=3
Fertilizer (tons): sugarcane=6 corn =2
150 workers are available, 200 tons of fertilizer are available
A) formulate a linear programming model that will enable the farmer to determine th number of acres where sugarcane and/or corn should be planted in order to maximize profit from his land. (using ALL 50 acres, but not all workers or fertilizers.
B) Make a graph of solution and determine the maximum profit. Show isoprofit lines and identify corner points and feasible region.
Explanation / Answer
let acres of sugarcanee be x and corn be y
5x + 3y <=150
6x + 2y < = 200
x >= 0
y>=0
to maximise 16000x + 8000y
y = 0 x = 30
max profit = 480000
