What are CAT Algebra Questions?

As discussed above, Algebra questions in CAT are important and come under the Quantitative Ability section. Infact, the maximum number of quantitative questions are from Algebra and Arithmetic in the aptitude test. Resultantly, this section is considered to be one of the highest-scoring. Speaking of the difficulty level of this section, CAT Algebra questions ask for a lot of calculations and mastery over quantitative formulas, thus, it scales between moderate to difficult level

For all those wondering, the Algebra section tests the candidates’ knowledge of linear and quadratic equations, logarithms, algebraic entities, etc. Here are the major topics that will be covered in the CAT quantitative aptitude section:

Important CAT Algebra Formulas for Preparation

To prepare for the CAT exam, the candidate needs to learn all the formulas by heart which will help them in solving all the questions. Here are some important algebraic formulas which will help you solve all the questions in the CAT exam. 

Linear Equation Formulas

Standard Formax + by = c

Quadratic Equation Formulas

Quadratic Formulax=-b±b2−4ac2a

Arithmetic Progression (AP)

General TermAn = a1 + (n – 1) d
Sum of first n TermsSn = n[2a+(n-1)d]/2

Geometric Progression (GP)

General TermAn = ar(n-1)
Sum of first n TermsIf r 1: Sn = a(rn – 1)r-1
If r = 1: S= na

Logarithms Formula 

loga (xy) = loga x + logay
loga(x/y) = loga x – logay
logx x = 1
Loga1 = 0
loga(xn) = n(loga x)
Logax = 1/(logx a)
Logax = (logbx)/(logba) = (log x)/(log a)

Exponents Formula

a0 = 1
am an = am + n
am/an = am – n
(am)n = amn

Number Properties

a2 – b2(a – b)(a + b)
(a + b)2a2 + 2ab + b2
(a – b)2a2 – 2ab + b2
a2 + b2(a + b)2 – 2ab
(a + b + c)2a2 + b2 + c2 + 2ab + 2bc + 2ca
(a – b – c)2a2 + b2 + c2 – 2ab + 2bc – 2ca
(a + b)3a3 + 3a2b + 3ab2 + b3 ; (a + b)3 = a3 + b3 + 3ab(a + b)
(a – b)3a3 – 3a2b + 3ab2 – b3 ; (a – b)3 = a3 – b3 – 3ab(a – b)
a3 – b3(a – b)(a2 + ab + b2)
a3 + b3(a + b)(a2 – ab + b2)
(a + b)4a4 + 4a3b + 6a2b2 + 4ab3 + b4
(a – b)4a4 – 4a3b + 6a2b2 – 4ab3 + b4
a4 – b4(a – b)(a + b)(a2 + b2)
a5– b5(a – b)(a4 + a3b + a2b2 + ab3 + b4)
