Explanation:  

Linear Programming is a mathematical technique for finding the optimal allocation of resources

  • In a graphical solution of solving linear programming problems to convert inequalities into equations, it is essential to use them to be equations.
  • linear programming is used for the optimization of limited resources when there is a number of alternate solutions possible of the problem.
  • In this linear term is used for variables and it simply means that the relationship between different variable can be represented in form of a straight line.

Requirement of Linear Programming

  • Objective Function: It is the main function; clearly identifiable and measurable in quantity.
  • Constraints: These are limited resources within which we have to obtain the objective.
