उत्तर

OABC is the feasible region whose corner points are O(0, 0), A(7, 0), B(3, 4) and C(0, 2)

Evaluating the value of Z, we get

Corner points Value of Z  
O(0, 0) Z = 5(0) + 7(0) = 0  
A(7, 0) Z = 5(7) + 7(0) = 35  
B(3, 4) Z = 5(3) + 7(4) = 43 ← Maximum
C(0, 2) Z = 5(0) + 7(2) = 14  

Hence, the maximum value of Z is 43 at (3, 4).
