## Important topics for Xam Idea Class 12 Maths Solutions Chapter 13 – Linear Programming

In this section, we will focus on the important topics of the chapter, linear programming.

• Linear Programming: It is a mathematical modelling technique used to achieve maximized or minimized linear functions when subjected to various constraints. This technique is most useful in business planning and industrial engineering for making decisions.
• Feasible Region: A region that is common to all the linear inequality constraints, is called a feasible region.
• Constraints: The system of linear inequalities (or equalities) under which the objective function is to be optimized is called constraints.
• Problem Constraints: Linear inequalities that are derived from the application, are called problem constraints.
• Objective functions: The function which is to be optimized (maximized/minimized) is called an objective function.
• Bounded region: Bounded region is a workable region that can be enclosed in a circle. A bounded region will have both maximum and minimum values.
• Unbounded region: A feasible region that cannot be enclosed in a circle. The objective function of the unbounded region is infinite.
• Corner Point: The vertices of the feasible region are called Corner point. When we draw the graph of the system of linear inequalities, then just by looking at the graph we can easily find out the corner point. But, not all the points at lines intersecting are corner points.
• Linear Programming Problems: A linear programming problem consists of a linear function to be maximized or minimized subject to certain constraints in the form of linear equations or inequalities.
• Different types of Linear Programming Problems: The various types of linear programming problems covered in this chapter are:

Manufacturing Problem: Under this, we maximize profit with the help of minimum utilization of the resources.

Diet Problem: Diet problems can be achieved if we select the set of healthy nutritive food required at minimum cost.

Transportation Problem: Transportation problems can be achieved by calculating the cheapest way of the transport of the product in minimum time.

Steps for solving linear programming problems using the corner point method:

• Converting the word problem into a mathematical equation by using given constraints.
• Solve the mathematical linear equation formed and plot the graph.
• Find the feasible region and determine its corner points.
• Evaluate the objective function at each corner point.
• If a feasible region is bounded, then the maximum and minimum values of the objective function are obtained.
• If a feasible region is unbounded, then the objective function has no maximum and minimum values.
