Inequalities are one of the important topic in the quantitative part of the CAT exam that can present tricky questions. These questions are often integrated with other sections like ratio and proportion, and progressions. Without a solid understanding of the concepts, candidates may find these questions time-consuming. Mastery of algebraic expressions and equations is crucial.
Practicing with CAT previous years' question papers is an excellent way to become familiar with the exam pattern. Additionally, taking free CAT mock tests can help you understand the types of questions that are likely to appear on the exam.
We have compiled all the inequality questions from past CAT exams. You can download these questions in a PDF format, which includes detailed solutions explained by CAT experts. Click the link below to download the CAT linear equation questions PDF with detailed video solutions
