Wondering how to crack CAT 2020 if you are a GEM? Have heard a lot about how it is grossly unfair to GEMs? You are at the right place then 😄

A favorite of the CAT QA Section, each year you get one to two questions involving quadratic inequalities. You may not study anything else, in inequalities, but do not skip Quadratic inequalities.

This is Set-40 of 100 LRDI Challenge Series. In this we have discussed a past year #CAT Question based on Caselets.

We have asked a question at the end of the video, Try solving it and us know your answer in the comment Section.  Write a comment
Write a comment... CAT QA Explainer | Algebra | Inequalites and Optimization | Maxima-Minima Basics

Over the last few years, CAT QA has slowly moved from solving equations to optimization problems. Maxima-Minima problems are very common in the CAT LRDI Section as well. In this session we discuss the basics of Inequalities and Optimization.

In this CAT QA Explainer we extend the concept of manipulating the roots a quadratic equation to higher order equations and then go about solving questions from past CAT and IIFT Papers.

Write a comment... CAT QA Explainer | Algebra | Quadratic Equations | Manipulating the roots of a Quadratic Equation

You don’t need to solve a quadratic to find the roots. In this CAT QA Explainer session, we use the properties of the roots of a quadratic equation to solve these CAT and XAT questions.

Write a comment... CAT QA Explainer | Algebra | Quadratic Equations | Discriminant | Roots of an equation

Quadratic Equations are a favorite of the CAT QA. Each year you get two to three questions from this area. Another low hanging fruit that students miss in Algebra over arcane shortcuts.

In the Concluding CAT QA Explainer for Indices Surds and Logarithms, we look at combination questions – use of more than one area from the QA Section. We look at how to extend what we learned

Logarithms are the favorite sub topic from Indices-Surds-Logarithms Triad. In this CAT QA Explainer session, we look at how basic questions from Logarithms break the tension during the QA section of CAT. Usually these questions can be solved with minimal manipulations or using options.
