Beneath are the theoretical concepts covered in Class 12 Maths Chapter 12 Linear Programming:
12.1 Introduction
This section summarises the preceding grades’ discussions of linear equations, linear inequalities, and linear inequalities applications. It uses an example to illustrate the concept of optimization problems and a subset of optimization problems known as linear programming problems. The maximization of profit while lowering the cost of a production unit is an excellent example of optimization.
12.2 Linear Programming Problem and its Mathematical Formulation
This section contains an example of a furniture trader who is attempting to optimize revenues by experimenting with various chair and table combinations.
12.2.1 Mathematical formulation of the problem
- The formulation of the above-mentioned mathematical issue is further explained in this part. The non-negative restrictions, objective function, and decision variables are all defined in this document.
- An objective function can be used to define the optimal value of a linear function.
- Finding the optimal value [maximum or minimum] of a linear function of variables subject to particular conditions and satisfying a set of linear constraints is a linear programming issue.
- Decision variables are variables that are involved in the objective function.
- The variables are restricted by the constraints.
12.2.2 Graphical method of solving linear programming problems
- The definition of the feasible region, feasible and infeasible solutions, optimal solutions, and bounded and unbounded feasible solution regions are all covered in this section. It gives a quick overview of the Corner Point Method, which is used to solve linear programming issues and includes examples.
- The feasible region is defined as the region obtained by the restrictions [including non-negative constraints].
- Possible solutions are the points that fall within the practicable zone.
- Infeasible solutions are points outside of the feasible zone.
- An optimal solution is a point in the feasible zone that offers the optimal value of the objective function.
12.3 Different Types of Linear Programming Problems
Different types of linear programming problems are discussed in this section.
12.3.1 Manufacturing problems
- These issues can be encountered in the manufacturing industry in order to maximize earnings while optimizing production. Profits can be determined by the number of employees, working hours, resources required, the market value of the product, demand for the product, supply of the product, and so on.
12.3.2 Diet problems
- Such issues entail optimizing the number of different types of foods consumed in order for the body to acquire the nutrients it requires. A diet problem’s aim will be to choose foods that provide the essential nutrition at a lower cost.
12.3.3 Transportation problems
- These issues concern the efficient delivery of manufactured items to various locations at the lowest possible cost. The analysis of transportation costs is very important for large companies because it caters to a wide area.

A few points on NCERT Class 12 Maths Chapter 12 Linear Programming
The chapter Linear Programming is divided into five units, each of which is worth five points out of a possible eighty. This chapter includes two exercises as well as a miscellaneous activity to help students fully comprehend the fundamentals of linear programming. The following are some of the topics covered in Chapter 12 of NCERT Exemplar Solutions for Class 12 Maths:
- A linear programming issue is one in which the goal is to determine the best value (maximum or minimum) of a linear function of numerous variables (called the objective function), given that the variables are non-negative and the variables satisfy a set of linear inequalities (called linear constraints). Decision variables are non-negative variables that are sometimes referred to as decision variables.
- The important linear programming problems are listed below:
- Diet problems
- Manufacturing problems
- Transportation problems
- The viable region (or solution region) of a linear programming problem is the common region given by all the constraints, including the non-negative constraints x 0, y 0.
- Possible solutions to the limitations are represented by points within and on the boundary of the viable zone.
- A solution that is outside the feasible zone is infeasible.
- An optimal solution is a point in the feasible zone that gives the objective function’s optimal value (maximum or minimum).
- If the viable zone is unbounded, there may be no maximum or minimum. If it does exist, it must occur at an R corner point.
- When addressing a linear programming issue, the corner point approach is applied.
- If two feasible region corner points are both optimal solutions of the same kind, i.e., they yield the same maximum or minimum, then every point on the line segment connecting them is likewise an optimal solution of the same type.
Students can learn about the following topics by studying Linear Programming in Class 12 with NCERT Exemplar Solutions: introduction, related terminologies such as constraints, objective function, optimization, different types of linear programming (L.P.) problems, mathematical formulation of L.P. problems, and more. viable and infeasible regions (bounded or unbounded), feasible and infeasible solutions, optimal feasible solutions, the graphical technique of solution for problems in two variables (up to three non-trivial constraints). Furthermore, the NCERT Exemplar Solutions boosts pupils’ confidence when it comes to taking future tests.
