A farmer possesses 100 hectometers of land and wants to grow corn and wheat. Cultivation of corn requires 3 hours per hectometer while cultivation of wheat requires 2 hours pert hectometer. Working hours cannot exceed 240. If he gets a profit of Rs. 20 per hectometer for corn and Rs. 20 per hectometer for wheat. The profit function for the farmer is

Choose an answer

P(x,y) = 20x + 15y

P(x,y) = 2x + 3y

P(x,y) = x + y

P(x,y) = 3x + 2y
