Answer:
Correct Answer: B
Solution:
Change the inequalities into equations and draw the graph of lines, thus we get the required feasible region. It is a bounded region, bounded by the vertices $ A(1,0),B(8,0) $ and $ C( \frac{12}{5},\frac{14}{5} ) $ . Now by evaluation of the objective function for the vertices of feasible region it is found to be maximum at (8,0). Hence the solution is $ z=3\times 8+0\times 2=24 $ .
