CBSE Class 12 Maths Chapter 12 Linear Programming MCQs

Maths Class 12 Linear Programming MCQs: The Central Board of Secondary Education is responsible for holding the annual term-end board exam for class 12, which is considered the most important exam for students and is essential to clear to graduate school. The question paper follows a fixed format every year and comprises questions of various types like short-answer, long-answer, descriptive and MCQs.

Each question requires a different approach to solving depending on its difficulty level and marks. Multiple choice questions are usually a requisite of all papers, but unlike other subjects, they aren’t direct in mathematics. Solving MCQs requires fast calculation skills and problem-solving from students. So it becomes necessary to go through several MCQs before appearing in the exam. You can check out the MCQs for CBSE Class 12 Maths Chapter 12 Linear Programming below.
