1, every point within and on the
boundary of the feasible region OABC
represents feasible solution to the problem For example, the point (10, 50) is a feasible
solution of the problem and so are the points
(0, 60), (20, 0) etc Any point outside the feasible region is
called an  infeasible solution For example,
the point (25, 40) is an infeasible solution of
the problem
