                                               XII MATHS ASSIGNMENT   Chapter- Linear Programming   12.1.1 An Optimisation Problem - A problem which seeks to maximise or minimise a function is called an optimisation problem. An optimisation problem may involve maximisation of profit, production etc or minimisation of cost, from available resources etc.  12.1.2 A Linnear Programming Problem (LPP) -  A linear programming problem deals with the optimisation (maximisation/ minimisation) of a linear function of two variables (say x and y) known as objective function subject to the conditions that the variables are non-negative and satisfy a set of linear inequalities (called linear constraints). A linear programming problem is a special type of optimisation problem.   12.1.3 Objective Function  - Linear function Z = ax + by, where a and b are constants, which has to be maximised or minimised is called a linear objective function.  12.1.4 Decision Variables In the objective func

The XI Mathematics annual examination is an important milestone for students studying in the science stream. It requires a thorough understanding of various mathematical concepts and problem-solving skills. To excel in this examination, students need to follow a structured study plan, practice regularly, and stay focused on mastering the key topics.
