उत्तर

Given that: Z = 3x + 4y and the constraints x + y ≤ 1, x ≥ 0, y ≥ 0

Let x + y = 1

x 1 0
y 0 1

The shaded area OAB is the feasible region determined by x + y ≤ 1, x ≥ 0, y ≥ 0

The feasible region is bounded.

So, maximum value will occur at the corner points O(0, 0), A(1, 0), B(0, 1).

Now, evaluating the value of Z, we get

Corner points Value of Z  
O(0, 0) 3(0) + 4(0) = 0  
A(1, 0) 3(1) + 4(0) = 3  
B(0, 1) 3(0) + 4(1) = 4 ← Maximum

Hence, the maximum value of Z is 4 at (0, 1).
