Distinguish between Basic feasible solution and Optimal solution in LPP

Distinguish between Basic feasible solution and Optimal solution in LPP. (Apr 2005)

Basic feasible solution means the 1^st simplex table. In basic feasible solution, the basic variables are slack variables. The Z value, i. e. profit value of that table is zero.

Optimal solution means the last table of simplex. In this table, all “C – Z (delta)” values, i. e. opportunity costs are either zero or negative. Hence, no further improvement in the solution is possible. The profit of this table is maximum. No further increase in profit is possible.
