CAT Quant: Algebra

Why this matters

Algebra questions in CAT rarely resemble textbook algebra problems directly. They are usually wrapped inside a word problem, an inequality constraint, or a functions-based puzzle, which is what makes this topic feel harder than its underlying mathematics actually is.

What you'll learn

The core sub-topics within Algebra, how CAT tends to disguise them inside word problems, and how to practice in a way that builds genuine comfort rather than memorized templates.

The core sub-topics

• Linear equations — including systems of two or three variables
• Quadratic equations — roots, sum and product of roots, nature of roots
• Functions — domain, range, composition of functions
• Inequalities — solving and interpreting inequality constraints

Why these questions feel harder than they are

CAT frequently presents an Algebra concept as a real-world scenario — ages, costs, mixtures — rather than a bare equation. The mathematics required is often no more advanced than a standard equation, but recognizing which concept applies, and translating the word problem into the correct equation, is the actual skill being tested.

A common mistake

Treating Algebra as a set of formulas to memorize, rather than a translation skill to practice. Two candidates who both know the quadratic formula perfectly can perform very differently if only one of them can reliably convert a wordy scenario into the correct quadratic equation in the first place.

A practical approach

1. Practice translating word problems into equations before worrying about solving speed
2. Build comfort with quadratic root relationships (sum and product of roots) since these often shortcut a full solve
3. Treat inequality questions as a distinct skill — they are graded differently from equation-solving and reward careful boundary-condition thinking
4. Revisit functions periodically even if they feel less frequent, since a single confident question here is easier marks than a mistimed attempt elsewhere
