Beginner-Friendly Algebra Strategies for the CAT Quantitative Aptitude Section

The first step to prepare for the Algebra section of CAT is to understand the CAT Quant syllabus and exam pattern. A total of 22 questions will be asked from the Quant section. The strategies to answer the CAT Algebra questions with highest accuracy have been provided below.

Strengthen Your Basics

Begin your CAT 2025 preparation by clearing your basic and fundamental concepts by referring to NCERT textbooks and foundational study materials. The topics you should focus on under CAT Algebra are Linear & Quadratic Equations, Logarithms, Inequalities, Progressions, Graphs, Functions, Algebraic Expressions to Polynomials. Gaining clarity on the basics and underlying concepts will help you make faster calculations with lesser errors. If you are using shortcuts or tricks, having a strong fundamental knowledge will help you use them correctly in twisted problems. Once you master the basics, you can move on to tricky and advanced concepts like functions, inequalities, and logarithms.

Learn Important Formulas

It is crucial to memorize key algebraic formulas and identities to solve the maximum number of problems accurately within the time limit. Note down all the formulas in one place to be able to revise them rapidly, retain them in your memory, and practise questions employing them repeatedly. Considering the time-pressure of the CAT exam, you must make use of formulas while solving direct or conceptual problems so that you can solve them in a few steps, rather than relying on lengthy calculations. Since the CAT has negative marking, it is feasible for you to recall key formulas and concepts for solving them directly and eliminate options quickly. Thus, you make less mistakes and consequently the number of correct attempts are increased in the CAT exam.

The key formulas that will help you solve Algebra problems efficiently for CAT are provided in the table below:

Topic	Formula
Logarithm	If x>0 and b is a constant (b≠1), then y=logbx if and only if x=by Logarithmic Identities Log b(xy) = log bx + log by Log b(x/y) = log bx – log by Log b(x^p) = p log bx Log b1 = 0 Log bb = 1 Log b(x) = 1 / log x(b) Change of base formula: log b(x) = log a(x) / log a(b) Common logarithm: log10(x) = log(x) Natural logarithm: log e(x) = ln(x) logaxy = logax + logay loga(x/y) = logax – logay logaxm = mlogax loganxm = m/nlogax logax = 1/logxa logaa = 1 loga1 = 0 alogam = m Logarithm Inequality If a > 1, p > 1 ⇒ logap > 0 If 0 < a <1, p > 1 ⇒ logap < 0 If a > 1, 0 < p < 1 ⇒ logap < 0 If p > a > 1 ⇒ logap > 1 If a > p >1 ⇒ 0 <logap <1 If 0 < a < p < 1 ⇒ logap < 1 If 0 < p < a < 1 ⇒ logap > 1 If logma > b ⇒ {a > mb, if m > 1 a < mb, if 0 < m < 1 logma < b ⇒ {a < mb, if m > 1a > mb, if 0 < m < 1 logpa > logpb ⇒ a ≥ b if base p is positive and >1 or a ≤ b if base p is positive and < 1 e., 0<p<1
	Arithmetic Progression (AP) Formula for n-th term: an = a1+(n−1)d Sum of first n terms: Sn = n/2[2a1+(n−1)d] Geometric Progression (GP) Formula for n-th term: an = a1rn−1 Sum, when r≠1: Sn = a1− 1−rn / 1 - r Harmonic Progression (HP)
Surds and Indices	Product rule: a^m × a^n = a^(m+n) Quotient rule: a^m / a^n = a^(m-n) Power rule: (a^m)^n = a^(m×n) Negative exponent rule: a^(-m) = 1 / a^m Rational exponent rule: a^(m/n) = nth root of a^m Fractional exponent rule: a^(p/q) = qth root of a^p Surds multiplication rule: √a × √b = √(ab) Surds division rule: √a / √b = √(a/b) Surds addition rule: √a + √b ≠ √(a+b) Surds subtraction rule: √a – √b ≠ √(a-b)
Linear Equation	ax + b = c; Here a,b,c are constants while x is Unknown a₁x+by+c₁ = 0 and a2x+ b₂y+c₂ = 0; a,b is not equal to 0 ???? = ???????? + ???? a1x + b1y = c1 and a2x + b2y = c2
Quadratic Equation	f(x) = 0 ax2+ bx + c = 0 D = (b2 - 4ac) ax2+ bx + c = 0 x = (-b ± √(b2 - 4ac)) / 2a x1 + x2 = -b/a x1 * x2= c/a x2 - (Sum of the roots) x + (Product of the roots) = 0 If a > 0 , then we can find the minimum value of the Quadratic equation as y= -D / 4a D=>Discriminant The value of x at the minima is x = (- b)/ (2a) -If a < 0 then we can find the maximum value of the Quadratic equation as y = - D/4a D => Discriminant The value of x at the maxima is x = (- b) / (2a)

Refer to the Best Algebra Books for CAT

You must refer to the following Best books for CAT 2025 exam for strengthening fundamentals, gaining detailed knowledge of all Algebra topics of varying difficulty levels from solved examples, mastering analytical skills, and practising different topics exhaustively.

NCERT Textbooks (Classes 9 & 10) for building a strong foundational knowledge

To know your KMAT exam centre and download the hall ticket (as per the latest 2026 admission cycle), candidates need to log in to the official KMAT portal using their registered credentials, where the admit card is released online. The hall ticket clearly mentions the exam centre address, reporting time, and exam timing, so students should check it carefully and carry a printed copy on exam day. Although KMAT is conducted by the exam authority, Lovely Professional University (LPU) guides applicants through the entire admission process and keeps them updated on entrance exam requirements, making the journey smoother and student-friendly.
