What is CBSE Class 12 Applied Maths Linear programming?
So now that we know what Applied Mathematics is all about, it will be easier for us to understand Linear programming. In the previous section, while discussing Applied Mathematics, we dropped a hint on CBSE Class 12 Linear Programming. To explain it in the shortest choice of words, Linear programming is the calculation of the best outcome of any event.
As per Wikipedia, Linear Programming is a method to achieve the best outcome (such as maximum profit or lowest cost) in a mathematical model whose requirements are represented by linear relationships. Linear programming is a special case of mathematical programming (also known as mathematical optimization).
CBSE 12 Applied Maths Linear programming is the calculation of best outcomes under given situations. The aim of the CBSE 12 Applied Maths Linear programming is to introduce you to the concept of Mathematical Modelling and build a strong foundation of concepts involved in it.

What to expect in the Linear Programming Exam?
Like we mentioned in our other article on CBSE Class 12 Financial Mathematics, “Syllabus is the guiding light”. It does actually stand true for every subject of CBSE Class 12. It is an undisputed fact that a student who knows the syllabus inside out has higher chances of topping the exam as compared to a student you don't know about the syllabus of the subject.
Let us figure out what the subject of Linear programming expects from you. And how you are expected to approach problems of the subject to score full marks in it. CBSE Class 12 Applied Mathematics (Linear programming) expects you to inculcate mathematical language and symbolism. This is encouraged for you to communicate and relate everyday experiences mathematically. So that you are able to understand the concepts and their utility in a much more profound way.
During your Class 12 Home and Pre Boards and CBSE Class 12 Board examinations, you should be ready for some questions based on logic and algorithms. While some of the questions will be straightforward and will ask you directly to calculate, while some others will try to cloud the question with unnecessary data and information. And some will even resemble questions from your textbooks exercises and reference books examples.
The purpose of questions in CBSE Class 12 Linear programming exam is to test your adaptability to solve logics and form algorithms. You should not be afraid of dealing with complex situations in questions. You should be agile and vigilant for any errors on the part of your calculation.
