CAT Logarithms is an important topic in the Algebra chapter of the Quantitative Aptitude (QA) section of the Common Admission Test (CAT). It covers properties of logarithms, change of base, equations and inequalities with logs. Practising CAT Logarithms 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, Logarithms accounted for 14 out of 330 Quantitative Aptitude questions, or approximately 4.2% of the questions analysed.

How to Prepare for CAT Logarithms Using PYQs
Follow a three-stage preparation plan to get the most out of the question bank.
- Build conceptual clarity: Revise properties of logarithms, change of base, equations and inequalities with logs before attempting timed practice.
- Practise topic-wise PYQs: Solve the 43 CAT Logarithms questions in this PDF. Record the year and slot, your accuracy, and the time taken.
- Attempt mixed sets: Once Logarithms 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 Logarithms contributed 4.2% of the five-year QA dataset analysed, give it time in proportion to its share, and keep preparing the other QA chapters as well.
