Important CAT Quant Formulas

Candidates explore these fundamental formulas that are essential for achieving exceptionally high scores in the CAT exam. Learning these formulas and their applications can improve problem-solving skills, enhance accuracy, and boost the chances of achieving an excellent percentile in the CAT exam.

CAT Arithmetic Formulas

Arithmetic formulas are shortcuts to solving math problems linked to addition, subtraction, multiplication, and division. Here is an analysis of some standard arithmetic formulas in simple terms:

Percentage Change(New Value – Old Value) / Old Value) × 100
Simple Interest(Principal × Rate × Time) / 100
Compound InterestP(1 + R/n)^(nt) (where P is principal, R is rate, n is number of times compounded annually, t is time in years)
Profit and LossSelling Price – Cost Price Loss = Cost Price – Selling Price
Average(Sum of all terms) / (Number of terms)
Ratio and ProportionIf a : b = c : d, then (a/b) = (c/d)
PartnershipRatio of investment × Time = Share in Profit or Loss

CAT Algebra Formulas

Algebra formulas take arithmetic a step additional by using variables to express unfamiliar numbers. Here are some familiar algebra formulas in simple terms:

Quadratic EquationFor ax² + bx + c = 0, x = (-b ± √(b² – 4ac)) / 2a
Arithmetic Progression (AP) Sumn/2  * (First Term + Last Term)`
Geometric Progression (GP) Suma * (1 – r^n) / (1 – r), where a is the first term and r is the common ratio
Binomial Theorem(a + b)^n = nC0 * a^n + nC1 * a^(n-1)b + … + nCn * b^n
Factorizationa² – b² = (a + b)(a – b) (a + b)² = a² + 2ab + b²
Linear Equationsc Solve for x: x = (c – by) / a Solve for y: y = (c – ax) / b
InequalitiesIf a > b, then a + c > b + c and ac > bc (for positive c)

CAT Geometry Formulas

Geometry formulas permit you to calculate lengths, areas, and volumes of different shapes. Here are some familiar ones for 2D and 3D shapes:

Area of Triangle0.5 * Base * Height
Perimeter of RectanglePerimeter = 2(Length + Width)
Circumference of Circle2πr (r is the radius)
Area of Circleπr²
Volume of Cylinderπr²h (h is the height)
Pythagorean TheoremIn a right triangle, a² + b² = c²
Area of Trapezoid0.5 * (Sum of parallel sides) * Height

CAT Number System Formulas

The number system formulas we commonly use do not include complex variables like algebra. They are more about shortcuts for calculations affecting typical sets of numbers. Mention below are some common examples:

Divisibility Rule by 2A number is divisible by 2 if its units digit is even (0, 2, 4, 6, 8).
Divisibility Rule by 3A number is divisible by 3 if the sum of its digits is divisible by 3.
Divisibility Rule by 9A number is divisible by 9 if the sum of its digits is divisible by 9.
Prime FactorizationExpressing a number as a product of prime numbers.
