NCERT Solutions Class 12 Maths Chapter 12 Linear Programming
NCERT solutions for class 12 maths chapter 12 linear programming applies the systems of linear inequalities/equations to solve real-life problems. In earlier classes, kids have learned about the various systems of linear equations and how to solve day-to-day problems by utilizing them. Another topic introduced to students previously is linear inequalities and systems of linear inequalities in two variables as well as how to find their solutions by graphical methods. This lesson combines the knowledge of these two concepts with certain newer optimization topics. Optimization problems are a general class of questions that seek to maximize (or, minimize) profit (or, cost). Thus, an optimization problem may involve finding the maximum profit, minimum cost, or minimum use of resources, etc. NCERT solutions for class 12 maths chapter 12 elaborate on such sums with the help of linear programming.
Class 12 maths NCERT solutions chapter 12 is a simple but very important chapter with a wide range of industrial applications in finance, statistics, mathematics, economics, etc. There are many methods to solve linear programming problems however, this lesson focuses on the easiest technique, that is, the graphical approach. When kids are solving such questions the most important point they have to keep in mind is that after reading the problem sum the mathematical formulation should be done correctly. Once they are able to derive the correct equations, getting the final answer is very easy. The NCERT solutions Chapter 12 linear programming has a detailed explanation of all the NCERT textbook sums. In this article, we will explore the study tips and tricks that will ferry students to success in exams. , download the exercises provided in the links below.

Linear programming problems came to the forefront in World War II when war operations had to be planned to minimize expenditure and maximize damage to the enemy. The first problem in linear programming was formulated in 1941 by the Russian mathematician, L. Kantorovich and the American economist, F. L. Hitchcock. However, both worked independently of each other. Further research gave birth to the concept as we know it today. There are many other such facts in the NCERT solutions class 12 maths that aim to provide a good understanding of linear programming while ensuring that kids remain motivated in studying these topics. The links to all these solutions are given below:

Topics Covered: The class 12 maths NCERT solutions chapter 12 is entirely based on linear programming. The topics covered are solving linear programming problems graphically, maximizing and minimizing a given equation as well as diet, manufacturing, and transportation questions.
Total Questions: Class 12 maths chapter 12 Linear Programming consists of 31 questions which can be further segregated into 14 simple, 10 tougher, and 7 complex high-order thinking sums.
List of Formulas in NCERT Solutions Class 12 Maths Chapter 12
NCERT solutions class 12 maths chapter 12 is not based on formulas rather it needs two other skills, namely, visualization and interpretation. Firstly, students need to interpret a problem sum and convert it into the correct minimization or maximization question. The next point is to draw the graph and shade the right area to represent the solution set. If children have issues in constructing the graph of a line, they can revisit topics on linear inequalities that they have seen in previous classes. Students must also learn how to pinpoint the optimal solution. The NCERT solutions for class 12 maths chapter 12 have certain terminologies that need to be understood before sums on the same can be solved. Some of them are as follows:
- Feasible or solution region: It is the common region determined by all the constraints including the non-negative constraints x ≥ 0, y ≥ 0 of a linear programming problem.
- Feasible solutions: These are the points within and on the boundary of the feasible region.
- Infeasible solution: These are the points outside the feasible region.
- Optimal solution: The point in the feasible region that gives the optimal value (maximum or minimum) of the objective function.
