3 Best YouTube Videos on Quantitative Aptitude – Linear Equations, Mixtures & Allegations, and Distance, Time and Speed by Physics Wallah

Quant in CAT rarely feels unfamiliar, it feels time-consuming. Questions often look standard, but small algebraic slips, lengthy arithmetic, or choosing the wrong method can cost valuable minutes. The real separator is not formula knowledge, but how efficiently you translate concepts into steps under pressure.

In these sessions, Physics Wallah breaks down three high-weightage areas, Linear Equations, Mixtures & Allegations, and Time–Speed–Distance, with an emphasis on method selection, simplification techniques, and avoiding common traps. The goal is to help you approach questions with more control rather than rushing through calculations.

Video 1: Linear Equations by Rahul Bathla Sir– Complete Algebra Framework with Shortcuts 

This session from the Algebra series focuses on Linear Equations, one of the foundational topics in CAT Quant. It covers core algebraic concepts, equation formation techniques, and methods to simplify and solve linear equations efficiently.

You learn how to translate word problems into equations, manage multiple variables, and apply shortcut approaches to reduce calculation time. With detailed explanations and exam-oriented problem types, the session strengthens algebraic clarity and helps improve accuracy in one of the most scoring areas of Quantitative Aptitude.

Video 2: Mixtures & Allegations – Ratio Logic, Alligation Method & Fast Calculation Techniques

In this session, Rahul Bathla Sir covers the second chapter, Mixtures and Allegations, a key arithmetic topic frequently tested in CAT. It explains how to approach mixture problems using logical ratio methods instead of lengthy calculations.

The video covers foundational concepts, an organised setup of mixture equations, and practical techniques to solve CAT-level questions efficiently. By focusing on clarity in ratio application and step-by-step simplification, the session helps students reduce errors and handle arithmetic-based problems with greater confidence.

Video 3: Time, Speed & Distance by Udit Saini Sir– Master Average Speed, Boats & Circular Track Problems

This session covers Time, Speed, and Distance in a comprehensive manner, moving from foundational concepts to advanced applications. It explains key subtopics such as average speed, time constant and distance constant concepts, boats and streams, linear races, and circular tracks.

You learn how to select the right approach based on the question type, apply efficient calculation strategies, and avoid common mistakes in multi-step problems. With detailed concept explanation and exam-focused examples, the session builds the precision and speed required to handle TSD questions confidently in CAT and other management entrance exams.

These three Physics Wallah Quant sessions provide focused coverage of important algebra and arithmetic topics tested in CAT. By combining clear concept explanation with shortcut techniques and exam-level application, they help improve speed, reduce calculation errors, and strengthen overall Quant performance.
