Linear Programming is an application-based chapter in the CBSE Class 12 Mathematics syllabus. It focuses on optimizing a linear objective function subject to linear constraints. This chapter helps students understand how mathematics is used in real-life decision-making problems related to profit maximization and cost minimization. CBSE frequently includes Assertion and Reason questions from Linear Programming to test conceptual clarity and logical reasoning.

Assertion and Reason questions consist of two statements:
Assertion (A) is a mathematical statement that may be true or false.
Reason (R) is a statement that explains or supports the assertion.
Students must choose the correct option based on the truth value and logical relationship between Assertion and Reason. These questions are designed to evaluate conceptual understanding rather than calculation skills.
Determinants play a crucial role in the CBSE Class 12 Mathematics syllabus. This chapter contributes significantly to board exam marks and also helps in understanding future topics. Assertion and Reason questions from determinants often appear in objective sections and are considered high-scoring when prepared well.
A determinant is a real number associated with a square matrix. It provides information about the nature of solutions of linear equations and the invertibility of matrices.
The order of a determinant depends on the number of rows and columns in the matrix. CBSE commonly asks questions from determinants of order 2 and 3.
Expansion of determinants using minors and cofactors is an important concept. Assertion questions often test whether students understand expansion along rows or columns.
Assertion and Reason questions consist of two statements. The Assertion is a mathematical statement that may be true or false. The Reason is a statement that explains or justifies the Assertion. Students must analyze both statements carefully and decide whether the Reason correctly explains the Assertion.
Linear Programming carries noticeable weight in the CBSE Class 12 Mathematics board examination. Questions are commonly asked from this chapter in objective and long-answer formats. Assertion and Reason questions are scoring when students clearly understand concepts such as feasible region and optimal solution.
A linear programming problem consists of an objective function, linear constraints, and non-negativity conditions. Assertion and Reason questions often test whether a given problem can be classified as a linear programming problem.
The objective function represents the quantity to be maximized or minimized. Many Assertion and Reason questions test identification of objective functions.
Constraints are linear inequalities or equations that restrict the solution. Assertion and Reason questions often test whether constraints are correctly formed from word problems.
Non-negativity restrictions ensure that variables do not take negative values. Assertion and Reason questions frequently test the necessity of these restrictions.
Each constraint is represented graphically as a line or half-plane. Assertion and Reason questions often test interpretation of these graphical representations.
The feasible region is the common region that satisfies all constraints. Assertion and Reason questions commonly focus on identifying feasible regions correctly.
Corner points are the vertices of the feasible region. Assertion and Reason questions often test why optimal solutions occur at corner points.
The optimal solution gives the maximum or minimum value of the objective function. Assertion and Reason questions may test whether a given solution is optimal.
A feasible region may be bounded or unbounded. Assertion and Reason questions often test whether an optimal solution exists in both cases.
If no common region satisfies all constraints, the problem has no feasible solution. This concept is frequently tested through Assertion and Reason questions.
These questions test whether students correctly identify feasible regions and explain the logic behind them.
Such questions focus on why the optimal value of the objective function occurs at a particular corner point.
Students may be asked whether a mathematical model is correct. The Reason often explains how constraints or objective functions are formed.
Students often make mistakes in plotting constraints. Another common error is incorrect identification of feasible regions. Confusion between bounded and unbounded regions also leads to wrong Assertion and Reason answers.
Students should understand each term used in Linear Programming clearly.
Regular practice helps improve accuracy in identifying feasible regions.
Each statement in Assertion and Reason questions should be analyzed independently.
CBSE emphasizes competency-based learning. Assertion and Reason questions are included in the objective section and test understanding of concepts rather than calculations.
With clear understanding of graphical methods and concepts, Linear Programming becomes a very scoring chapter. Assertion and Reason questions are mostly conceptual and straightforward.
