NCERT CBSE Class 12 Maths Chapter 12

The NCERT Solutions for Class 12 Maths Chapter 12 Linear Programming cover all topics and sub-topics covered in this chapter. Some of them have been discussed below.

Feasible region

In this section, you will get to know about the meaning of feasible regions. A solution region or feasible region is defined as the common region that is represented by all the boundaries, including the non-negative boundaries x ≥ 0, y ≥ 0.

This chapter also teaches you about feasible choice, infeasible choice, and infeasible solution.

Optimal solution

Under this topic of CBSE NCERT Class 12 Maths Chapter 12, you will get to know about some fundamental theorems like the optimal solution of an objective function. The optical solution in an objective function of any point in the feasible region gives the optimal maximum value or the optimal minimum value.

Theorems of linear programming

In this section, of NCERT Class 12 Maths Chapter 12, you will learn about crucial theorems that will help in solving problems related to linear programming. The theorems are elaborated with examples so that you do not face any difficulties in learning. Following are the two theorems covered in this section on NCERT Class 12 Maths Chapter 12.

Theorem 1

Let R be the feasible region (convex polygon) for a linear programming problem.

Let Z = ax + by be the objective function. 

When Z has an optimal value (Maximum or minimum) where the variables x and y are subject to boundaries described by linear inequalities, this optimal value must occur at a corner point (vertex) of the feasible region.

Theorem 2

Let R be the feasible region (convex polygon) for a linear programming problem.

Let Z = ax + by be the objective function. 

If R is constrained, then the objective function Z has both minima, and maximum value of R and each of these occurs at a corner point (vertex) of R

Class 12 Maths Linear Programming chapter teaches you about the corner point method of solving linear programming problems within a feasible region. It also teaches you the graphical method to solve linear programming problems and Isom-profit or iso-cost method of solving a linear programming problem.
