answered-by-expert Expert Answer
Let x = number of bags of rice , y =  number of bags of wheat
The linear progrmming problem will be:
Max Z = 11x + 9y subject to
3x + 2y ? 25
x + y ? 10
x, y ? 0
 
When you will draw the graph, you will get the maximum profit at point (5, 5) - the point of intersection of the two lines.
 
Thus, for earning maximum profit, 5 bags of rice and wheat should be purchased and sold.
 
Maximum profit = 11(5) + 9(5) = 55 + 45 = Rs 100

In order to ensure optimal health (and thus accurate test results), a lab technician needs to the dogs a daily diet containing a minimum of 24 grams (g) of fat, 36 g of carbohydrates, and 4 g of protein. But the dog should be fed no more than five kg of food a day. Rather than to order dog-food that is custom-blended, it is cheaper to order Food X and Food Y, and blend them for an optimal mix. Food X contains 8 g of fat, 12 g of carbohydrates, and 2 g of protein per kg, and costs Rs0.20 per kg. Food Y contains 12 g of fat, 12 g of carbohydrates, and 1 g of protein per kg, at a cost of Rs0.30 per kg. What is the optimal blend?
