Question

Given a minimization problem with the following constraints: 
 x1+x3>=5 
 x1+2x2+4x3>=20 
 And the following optimal solution: 
 Xb=(x1, x2)=(5, 5).  
 Xn=(e1, e2, x3) With reduced costs (1/3, 2/3, 8/3) respectively. 
 Select the right answer:

Answer

Reducing independent term of the first constraint from 5 to 4, would increase the value of the objective function by 1/3

Answer

Increasing independent term of the first constraint from 5 to 4, would increase the value of the objective function by 1/3

Answer

Increasing independent term of the first constraint from 5 to 4, would reduce the value of the objective function by 1/3

Answer
