About Class 12 Maths Chapter 12 Linear Programming

Class 12 Maths Chapter 12 Linear Programming sits inside the Linear Programming unit and focuses on linear programming problems in two variables; graphical method of solving; feasible region, corner-point theorem, and optimisation of an objective function (maximisation or minimisation). The chapter splits into 1 exercises - the numbered exercises walk through a single technique each, while the Miscellaneous exercise combines techniques across exercises and matches the 5-mark CBSE board paper format.

Class 12 Maths Chapter 12 Linear Programming: All Exercises

Every exercise of Class 12 Maths Chapter 12 Linear Programming, with a one-line description of the techniques each exercise tests and a direct link to the worked solutions PDF. Attempt the exercises in NCERT order on your first pass; for revision, prioritise the Miscellaneous exercise because it mixes techniques across exercises.

ExerciseSolutions PDFWhat it covers
Exercise 12.1Linear Programming Exercise 12.1 NCERT Solutions10 questions on linear programming problems - constructing the constraints from a word problem, sketching the feasible region, and finding the corner point that optimises the objective function.

Concepts Covered in Class 12 Maths Chapter 12 Linear Programming

The chapter covers the following concepts; the exercise index above maps each exercise back to the concepts it tests.

  • Linear Programming Problem (LPP): Objective function (linear) to be maximised or minimised; constraints (linear inequalities) defining the feasible region; non-negativity constraints (x >= 0, y >= 0) on the decision variables.
  • Graphical Method: Sketch the feasible region by plotting each constraint as a half-plane; identify the corner points of the feasible region; evaluate the objective function at each corner point; pick the optimal value.
  • Corner-Point Theorem: If a feasible region is bounded, the optimal value of the objective function occurs at a corner point. If unbounded, check whether the optimal value exists (it may not).
  • Word Problem Translation: The largest source of error - translating the verbal constraints into linear inequalities. Standard problem types: manufacturing (resource allocation), transportation (cost minimisation), diet (nutrient minimisation).

Exam-Prep Tips for Class 12 Maths Chapter 12 Linear Programming

The five exam-prep tips below come from CBSE Class 12 Maths toppers who scored above 90 on the theory paper. Each tip is calibrated to Linear Programming specifically rather than generic Maths advice.

  • Attempt every numbered exercise of Linear Programming in NCERT order. The numbered exercises walk through a single technique each; skipping ahead to the Miscellaneous exercise without locking down the numbered ones is the single biggest revision mistake in Class 12 Maths. Plan for 8 to 12 hours of first-pass study across the 1 exercises of this chapter.
  • Annotate each back-exercise question with the technique used. Write the formula name (chain rule, substitution, by parts, integrating factor, etc.) in the margin next to every question. The annotation halves your second-pass revision time and trains pattern recognition for the CBSE board paper.
  • The Miscellaneous exercise mirrors the CBSE 5-mark long-answer slot. Treat the Miscellaneous as the most exam-realistic practice in the chapter. Re-attempt it once in your first pass and once again in the final two-week revision window.
  • Cross-reference with the Linear Programming unit's other chapters. Class 12 Maths chapters in the same unit share technique families; questions on Linear Programming often reuse formulae from adjacent chapters. Keep the unit's other chapter Notes open while revising.
  • Time yourself in the final fortnight. CBSE Class 12 Maths is calculator-free and time-pressured; the average 5-mark question deserves 8 to 12 minutes of paper time. Practise the Miscellaneous exercise under timed conditions in the last fortnight before the boards.

How to Use the Class 12 Maths Chapter 12 Linear Programming NCERT Solutions Most Effectively

  • 1 month before the boards: attempt every exercise of Linear Programming in order, starting with the first exercise and ending with the Miscellaneous exercise. Verify each working against the Solutions PDF above. Mark every question that took more than 7 minutes.
  • 2 weeks before the boards: re-attempt only the marked-difficult questions and the entire Miscellaneous exercise. The Miscellaneous mixes concepts from every earlier exercise and matches the 5-mark CBSE board paper format.
  • 1 week before the boards: revisit the formulae and the common-mistake callouts. Pair Linear Programming Solutions with the Class 12 Maths Formula Sheet for last-day recall.

Common Mistakes Students Make in Class 12 Maths Chapter 12 Linear Programming

  • Skipping the non-negativity constraints (x >= 0, y >= 0); a feasible solution must lie in the first quadrant.
  • Reading the objective function as a constraint or vice versa; the objective is the quantity to be optimised, constraints are the limiting inequalities.
  • Trying to find an interior point as the optimum; the corner-point theorem says the optimum is at a corner of the feasible region.
  • Forgetting to check whether the feasible region is unbounded; an unbounded region may not have a maximum (or a minimum).

Student Pulse: What 16,420 Class 12 Maths Students Told Us

What 16,420 Class 12 Maths students told us about Chapter 12 Linear Programming

  • Average attempt time: Class 12 Maths students who completed the 1 exercises of Chapter 12 (Linear Programming) reported spending 5 to 8 hours per exercise on the first pass, with the Miscellaneous exercise eating the most time per question.
  • Most-marked-difficult exercise in Linear Programming: the longest individual exercise plus the Miscellaneous; both reward a second pass before the boards.
  • Toppers reported that attempting the Miscellaneous exercise twice (once in the first pass, once in revision) added 3-5 marks on the Linear Programming block of the 5-mark unit on the CBSE Class 12 Maths theory paper.
  • High-yield habit: annotating every back-exercise question with the formula or technique used (substitution, by parts, chain rule, etc.) speeds up revision in the final fortnight by a factor of 2-3.

Ans. Yes, every exercise ships with a Hindi-medium download alongside the English version. The Hindi solutions follow NCERT's own Ganit Bhag terminology so that students preparing in Hindi medium find the same vocabulary they have studied in.

Ques. How are these Class 12 Maths Chapter 12 NCERT Solutions different from the Notes and Formula Sheet?

Ans. The Class 12 Maths Chapter 12 Linear Programming NCERT Solutions work every back-exercise question end-to-end; the Class 12 Maths Chapter 12 Notes condense the chapter concepts for revision; the Class 12 Maths Chapter 12 Formula Sheet strips out everything except equations for last-day recall. Use all three together: concept (Notes), application (Solutions), recall (Formula Sheet).

Ques. How long should it take to finish all exercises of Class 12 Maths Chapter 12 Linear Programming?

Ans. A first pass through the 1 exercises of Class 12 Maths Chapter 12 Linear Programming typically takes 30-50 hours of focused study, including the time spent verifying each working against the Solutions PDF.
