Top 4 Videos on Modulus for Quantitative Aptitude for CAT by PW

Modulus questions in CAT Quantitative Aptitude can be difficult when you need to consider sign changes, interpret graphs or divide a problem into different cases. You may understand the basic rules but still struggle with nested expressions, inequalities, minimum values or questions involving multiple modulus terms. Choosing the wrong case can lead to an incorrect answer, even when your algebra is correct.

PW’s MBA Wallah videos help you understand Modulus through worked examples, graphical methods, shortcut techniques and CAT-level practice. You can begin with the basic concepts, then move to graphs, equations and special cases as your understanding improves.

These lessons also help you practise previous-year questions and compare different approaches to solving modulus problems.

Video 1: Understand Modulus Rules and Shortcuts with Exam-Focused Questions

This Modulus class revises fundamental concepts, key properties, rules, and standard solving methods. You will work through CAT-level questions while learning practical shortcuts, faster calculation approaches, and ways to avoid common mistakes.

The session connects conceptual understanding with exam-focused problem-solving, helping you choose a suitable method for different types of Quantitative Aptitude questions. If you already understand the basic rules but take too long to solve questions or frequently make calculation errors, use this lesson for revision.

Practise the examples and compare your approach with the methods demonstrated to identify where you can simplify your working and improve accuracy during timed CAT practice.

Video 2: Understand Modulus Graphs, Equations and Solution Counts

This Algebra session focuses on solving modulus problems through graphs. You will learn graph basics, how to plot expressions containing multiple modulus terms, identify critical cases and determine ranges or solution counts.

The lesson compares traditional and shortcut methods for modulus equations and covers transformations, special cases, quadratic expressions inside modulus and CAT previous-year questions.

If you find it difficult to decide which cases to consider or interpret the graph of a modulus expression, these examples can help you understand the relationship between the graph and its solutions.

Watch this after revising the fundamentals to practise graph-based questions and improve your approach to CAT Quantitative Aptitude.

Video 3: Practise Modulus Special Cases, Inequalities and Nested Graphs

This advanced Modulus lecture focuses on special cases that require careful analysis. You will study sign analysis, critical points, equations, inequalities, graph transformations, mirror images and problems involving multiple variables.

The session also covers integer solutions, ordered pairs, contradictory cases and nested modulus graphs. CAT Previous-Year Questions are solved using options, logic, factoring and shortcut methods, with coordinate geometry applications included for additional practice.

If you understand the basic rules but struggle with complicated expressions or inequalities, use this lesson to practise selecting the relevant cases and checking possible solutions. It is particularly useful when revising challenging Modulus questions before attempting CAT Mock Tests.

Video 4: Revise Modulus Fundamentals with One-Shot Revision and Practice Questions

This One-Shot lesson introduces the Modulus Function, starting with its basic meaning and moving towards CAT-level applications. You will revise core rules, methods for finding minimum values and an important modulus concept before applying them to practice questions.

The session also includes previous-year questions and additional problems for guided solving. If you are learning Modulus for the first time or need to revisit the basics before attempting tougher questions, this lesson gives you a starting point.

Use the examples to connect the rules with their applications and practise choosing suitable methods before moving to advanced equations and graphs.

These four PW videos cover Modulus from fundamental rules to graphs, equations, inequalities and advanced special cases. Start with the One-Shot lesson to build your understanding, then use the graph-focused session to practise interpreting expressions and finding solutions.

Move to special cases once you are comfortable with the basics, and revise the final lesson to practise shortcuts and exam-level questions.

While practising, pay attention to sign changes, critical points and the conditions that determine each case. Review incorrect answers to understand where your approach went wrong.

Regular practice with these lessons can help you solve Modulus questions more accurately and prepare more effectively for CAT Quantitative Aptitude.
