Complete Karnataka PGCET MBA quant formula list: topic-wise formulas, quick tips and a 30-day plan

The Karnataka PGCET MBA 2026 exam is scheduled for 14 June 2026 and the paper is 100 MCQs across four sections with no negative marking , so formula mastery directly improves both speed and accuracy. This Karnataka PGCET MBA quant formula list gives you chapter-wise formulas, memorisation tips, mental-maths drills and a ready-to-follow 30-day plan you can start today.

Why a dedicated Karnataka PGCET MBA quant formula list matters

The PGCET quant section is largely concept- and formula-based. When you know the right formula, you cut down calculation time and avoid multiple re-workings on the clock. With no negative marking , attempting smartly becomes easier if your formulas are automatic.

Arithmetic topics return the most marks in past papers — percentages, averages, ratio, and simple & compound interest (SI-CI) are high-yield. Use previous years' papers to spot which formulas appear often and practise those first.

How to use the Karnataka PGCET MBA quant formula list: quick prep checklist

• Make a short chapter-wise formula notebook. Carry it during revisions.
• For each formula, solve 5–10 questions without a calculator to build recall and speed.
• Schedule regular mocks and reserve daily slots for your weakest topics.
• Keep a one-page printable cheat sheet of only must-know formulas for the final week.

High-yield arithmetic formula bank (easy to memorise, high impact)

Percentages (must-know)

• X is what percentage of Y = (X / Y) × 100
• X% of Y = (X × Y) / 100
• Successive change: Net % = R1 + R2 + (R1 × R2)/100
• Percentage change = (Difference / Original) × 100

Averages, Ratio & Proportion

• Average of n numbers = (Sum of numbers) / n
• If A : B = p : q and total is T, A = (p / (p+q)) × T
• Mean relation for weighted averages: (Σ weight × value) / Σ weight

Profit & Loss

• S.P. = C.P. + Profit; S.P. = C.P. − Loss
• Profit% = (Profit / C.P.) × 100; Loss% = (Loss / C.P.) × 100
• To convert, S.P. = C.P. × (1 + Profit%/100)

Simple Interest (S.I.) & Compound Interest (C.I.)

• S.I. = (P × R × T) / 100
• Amount for annual CI: A = P(1 + R/100)^n ; CI = A − P
• Half-yearly compounding: A = P(1 + R/(2×100))^(2T)
• Difference CI − SI for 2 years = P × (R/100)^2

High-yield tip: practice successive percent increases and decreases (they are frequent in PGCET).

Number system and algebra: compact formulas and identities

Number system essentials

• Product = HCF × LCM (for two numbers)
• Sum of first n naturals = n(n+1)/2
• Sum of first n even = n(n+1); sum of first n odd = n^2
• Sum of squares = n(n+1)(2n+1)/6; sum of cubes = (n(n+1)/2)^2

Algebra identities and quick-use rules

• (a ± b)^2 = a^2 + b^2 ± 2ab
• a^2 − b^2 = (a − b)(a + b)
• (a + b)^3 = a^3 + b^3 + 3ab(a + b)
• Quadratic formula: x = [−b ± sqrt(b^2 − 4ac)] / (2a)
• Log rules: log(mn) = log m + log n ; log(m^n) = n log m ; change-of-base formula

Exam tip: for quick factor detection, look for perfect-square patterns or use (a+b)^2 expansion to convert expressions into solvable forms.

Geometry, mensuration and circular-track formulas (visual memory tips)

Areas and basic 2D formulas

• Triangle area: (1/2) × base × height
• Heron: area = sqrt[s(s−a)(s−b)(s−c)] where s = (a+b+c)/2
• Rectangle: length × breadth; Square: side^2
• Circle: area = πr^2 ; circumference = 2πr

Volumes & surfaces (short forms)

• Cube: V = a^3 ; TSA = 6a^2
• Cuboid: V = l × b × h ; TSA = 2(lb + bh + hl)
• Cylinder: V = πr^2h ; CSA = 2πrh
• Cone: V = (1/3)πr^2h ; CSA = πrl
• Sphere: V = (4/3)πr^3 ; SA = 4πr^2

Circular track and meeting problems

• First meeting (same direction) = D / |a − b|
• First meeting (opposite direction) = D / (a + b)
• Time to meet at starting point typically uses LCM of lap times: LCM(D/a, D/b)

Visual tip: sketch speeds as fractions of lap-time. Convert to relative speed early to avoid unit mistakes.

Permutation, combination and probability: go-to formulas for quick answers

Permutations & combinations

• n! ; nPr = n!/(n−r)! ; nCr = n!/(r!(n−r)!)
• Circular arrangements = (n − 1)!
• Repetition allowed for arrangements of length r from n types = n^r

Probability basics

• P(E) = favorable outcomes / total outcomes
• 0 ≤ P(E) ≤ 1
• Addition rule: P(A ∪ B) = P(A) + P(B) − P(A ∩ B)
• For independent events: P(A ∩ B) = P(A) × P(B)

Exam tip: convert combinatorics problems to counts quickly by checking whether order matters and whether repetition is allowed.

Mistakes students make applying formulas (common pitfalls and fixes)

Mixing base values in percentage and interest questions

• Pitfall: using new value as base instead of original. Fix: mark the ‘original’ value clearly before applying percent formula.

Wrong units in TSD and train problems

• Pitfall: mixing km/h with m/s or forgetting to add lengths when crossing. Fix: convert units at the start and write lengths explicitly.

Sign errors in work and pipes problems

• Pitfall: treating emptying pipe as positive efficiency. Fix: assign negative rates to emptying pipes and add algebraically.

Misusing LCM for circular start-point timing

• Pitfall: applying LCM on speeds instead of times. Fix: compute lap times (D/ speed) first, then take LCM.

Daily practice routine and mental-maths drills

Build mental shortcuts

• Memorise multiplication tables up to 20 and common squares/cubes.
• Keep quick fraction-to-percentage conversions ready (1/3 = 33.33%, 3/8 = 37.5%).
• Spot factors early: if a number ends with 0 or 5 check divisibility by 5; sum digits for 3 and 9.

Practice rule

• For each formula: solve 5–10 focused questions without a calculator.
• Do timed mini-sets of 20 questions: 25 minutes, then review mistakes for 20 minutes.

Quick mental drill: take 10 minutes daily to multiply two-digit numbers mentally using (a+b)(a−b) or (a+b)^2 − a^2 − 2ab patterns.

30-day focused plan till the exam (sample schedule and time allocation)

Use this schedule if your exam is on 14 June 2026 . The plan balances formula revision, practice, mocks and tapering.

Notes: - Keep Sundays lighter: 60–90 minutes for review. - Swap topics based on your weak areas but keep arithmetic front-loaded—it's high-impact.

Sectional time management and mock-test strategy

Suggested split for the 100-MCQ, 4-section paper (adjust if section weights differ):

Mock-test steps

• Simulate full exam conditions: same time limits and no calculator.
• Track time per section and per question type.
• After each mock: log errors and classify them (formula mistake, calculation, reading error). Focus next week on the most frequent type.

Create printable revision tools: one-page sheet and formula notebook tips

One-page cheat sheet (what to include)

• Only must-know formulas: percentages, averages, ratio, SI-CI, TSD basics, time & work formulas, nCr/nPr, and common geometry area/volume formulas.
• Short reminders: conversion factors, sign rules for pipes, how to convert speeds between km/h and m/s.
• A 6–8 item error checklist: units, base value, signs, order of operations.

Formula notebook organisation

• One section per topic with 4–6 example problems pinned under each formula.
• Use coloured tabs for arithmetic, algebra and geometry so you can flip to high-yield areas in seconds.

Resources to amplify formula retention (papers, tests, and tools)

• Use previous year papers to identify frequent formula applications and question patterns.
• Take regular free mocks and short sectional tests; track improvement per topic.
• Flashcards or spaced-repetition apps help memorise formulas—write one formula per card and test daily.
• Practise without a calculator to improve mental maths as recommended for PGCET preparation.

Wrap-up: action plan you can start today

Three immediate actions:

1. Make a short chapter-wise notebook and write the top 3 formulas of each chapter.
2. Do a timed set of 20 quant questions under exam-like conditions and mark the errors.
3. Schedule your first full-length mock within the next 7 days and a second mock after 10 days to measure progress.

If the exam date moves, keep the same structure: front-load arithmetic, maintain daily mocks and taper to short, sharp formula revision in the final week.
