उत्तर

ABCA is the feasible region.

Corner points C(0, 3), B(0, 5) and for A

We have to solve equations

x + 3y = 9 and x + y = 5

Which gives x = 3, y = 2

i.e., A(3, 2)

Evaluating the value of Z, we get

Corner points Value of Z  
A(3, 2) Z = 11(3) + 7(2) = 47  
B(0, 5) Z = 11(0) + 7(5) = 35  
C(0, 3) Z = 11(0) + 7(3) = 21 ← Minimum

Hence, the minimum value of Z is 21 at (0, 3).

To maintain his health a person must fulfil certain minimum daily requirements for several kinds of nutrients. Assuming that there are only three kinds of nutrients-calcium, protein and calories and the person's diet consists of only two food items, I and II, whose price and nutrient contents are shown in the table below:
 

  Food I
(per lb)
  Food II
(per lb)
    Minimum daily requirement
for the nutrient
 Calcium 10   5     20
Protein 5   4     20
