Class 11 Mathematics — Chapter 6: Linear Inequalities

66 practice questions · 22 Easy · 22 Medium · 22 Hard

Practise Class 11 Mathematics Chapter 6, "Linear Inequalities", with 66 NCERT-aligned multiple-choice questions. The set is split into 22 Easy, 22 Medium and 22 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams, JEE Main and JEE Advanced.

"Linear Inequalities" is one of the chapters where problem-solving speed, formula recall and step-by-step reasoning really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.

Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Linear Inequalities, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 11 Mathematics mastery score. A few sample questions are shown below; sign in free to practise all 66.

Key concepts: Linear Inequalities (Class 11 Mathematics)

This chapter solves linear inequalities in one and two variables, algebraically and graphically, including systems of inequalities.

Linear inequality
An inequality like ax + b < 0 (or ≤, >, ≥); the solution is a range of values, not a single number.
Rule of signs
Multiplying or dividing both sides by a negative number reverses the inequality sign.
Solution on the number line
Solutions of one-variable inequalities are intervals shown on the number line.
Two-variable inequalities
Represented as a half-plane; the boundary line is solid (≤, ≥) or dashed (<, >).
Systems of inequalities
The common (feasible) region is the intersection of all the individual solution regions — the basis of linear programming.

Key formulas — Linear Inequalities

Sign-reversal rule
if a < b and c < 0, then ac > bc

💡 Exam tips for Linear Inequalities

  • Reverse the inequality sign whenever you multiply or divide by a negative number — the most common mistake.
  • For two-variable inequalities, test a point (often the origin) to decide which side to shade.

Sample questions

Q1Easy

Solve 2x > 6:

A.x > 3✓ correct
B.x < 3
C.x = 3
D.x ≥ 3
Why

Divide both sides by 2.

Q2Medium

Solve 1 ≤ x+2 < 5:

A.−1 ≤ x < 3✓ correct
B.1 ≤ x ≤ 5
C.x > 0
D.x ≥ 1
Why

Subtract 2 throughout.

Q3Hard

Solve |x|<3:

A.−3 < x < 3✓ correct
B.x > 3
C.x < −3
D.x = 0
Why

|x|<a ⇔ −a<x<a.
