  1. For the linear programming problem 
    Maximize z = x1 + 2x2 + 3x3 - 4x4 
    Subject to      2x1 + 3x2 - x3 - x4 = 15  
                           6x1 + x2 + x3 - 3x4 = 21 
                           8x1 + 2x2 + 3x3 - 4x4 = 30 
                           x1, x2, x3, x4 ≥ 0, 
    x1 = 4, x2 = 3, x3 = 0, x4 = 2 is
    2. A.
