CAT Linear Equations is an important topic in the Algebra chapter of the Quantitative Aptitude (QA) section of the Common Admission Test (CAT). It covers simultaneous equations, word problems, systems with no or many solutions. Practising CAT Linear Equations PYQs helps candidates understand question patterns, improve calculation speed, and identify concepts that appear frequently. Based on a five-year analysis of CAT 2021-2025, Linear Equations accounted for 11 out of 330 Quantitative Aptitude questions, or approximately 3.3% of the questions analysed.

How to Prepare for CAT Linear Equations Using PYQs
Follow a three-stage preparation plan to get the most out of the question bank.
- Build conceptual clarity: Revise simultaneous equations, word problems, systems with no or many solutions before attempting timed practice.
- Practise topic-wise PYQs: Solve the 53 CAT Linear Equations questions in this PDF. Record the year and slot, your accuracy, and the time taken.
- Attempt mixed sets: Once Linear Equations is comfortable, mix it with other Algebra questions. Review incorrect answers and identify whether the mistake came from concept selection, calculation, or time management.
Because Linear Equations contributed 3.3% of the five-year QA dataset analysed, give it time in proportion to its share, and keep preparing the other QA chapters as well.
