MAT September 2026 Mathematical Skills: Important Topics, Formulas and Practice Tips

The Mathematical Skills section of MAT September 2026 has 40 questions worth 40 marks, and Arithmetic topics alone account for nearly 38 to 45% of all questions in this section.

Conducted by AIMA (All India Management Association), MAT is held in Paper Based Test, Computer Based Test and Internet Based Test modes across multiple sessions each year. The Mathematical Skills section tests quantitative ability across six major topic areas. Knowing the chapter-wise weightage helps you allocate study time more efficiently and focus on high-yield topics first.

• Mathematical Skills section: 40 questions, 40 marks with a recommended attempt time of 30 to 35 minutes
• Arithmetic is the highest-weightage area with approximately 15 to 18 questions expected based on previous years
• Negative marking applies: -0.25 marks per wrong answer
• Attempting 28 to 32 questions with high accuracy typically places students in the 70 to 80 percentile range in this section
• MAT September 2026 registrations are open on the official AIMA portal

Important Formulas for MAT Mathematical Skills

Memorising key formulas reduces solving time significantly in the exam. Below are the most frequently tested formulas across high-weightage topics in the MAT Mathematical Skills section.

Arithmetic Formulas

• Profit Percentage = (Profit / Cost Price) x 100
• Simple Interest = (P x R x T) / 100
• Compound Interest = P x [(1 + R/100)^T - 1]
• Time and Work: If A completes a job in x days and B in y days, together they finish it in (x x y) / (x + y) days
• Average Speed (for equal distances) = (2 x S1 x S2) / (S1 + S2)
• Percentage Change = [(New Value - Old Value) / Old Value] x 100
• Alligation Rule: (Quantity of Cheaper) / (Quantity of Dearer) = (Price of Dearer - Mean Price) / (Mean Price - Price of Cheaper)

Algebra Formulas

• Sum of AP = n/2 x [2a + (n-1)d]; nth term = a + (n-1)d
• Sum of GP = a x (r^n - 1) / (r - 1) for r not equal to 1
• Quadratic Roots = [-b plus or minus root(b^2 - 4ac)] / 2a
• Key Identities: (a+b)^2 = a^2 + 2ab + b^2; (a-b)^2 = a^2 - 2ab + b^2; a^2 - b^2 = (a+b)(a-b)

Geometry and Mensuration Formulas

• Area of Triangle = (1/2) x base x height; using Heron formula: root[s(s-a)(s-b)(s-c)] where s = (a+b+c)/2
• Area of Circle = pi x r^2; Circumference = 2 x pi x r
• Volume of Cylinder = pi x r^2 x h; Curved Surface Area = 2 x pi x r x h
• Volume of Cone = (1/3) x pi x r^2 x h; Slant Height = root(r^2 + h^2)
• Volume of Sphere = (4/3) x pi x r^3; Surface Area = 4 x pi x r^2

Modern Mathematics Formulas

• Permutations: nPr = n! / (n-r)!
• Combinations: nCr = n! / [r! x (n-r)!]
• Probability = Number of Favourable Outcomes / Total Number of Outcomes
• Addition Rule: P(A or B) = P(A) + P(B) - P(A and B)

High-Priority Topics to Focus On for MAT September 2026

With 40 questions to attempt in 30 to 35 minutes, focusing on high-weightage topics first is the most efficient strategy. Arithmetic, Algebra and Geometry together account for approximately 65 to 80% of all questions in the MAT Mathematical Skills section.

Arithmetic — Highest Priority

• Percentages and Profit and Loss — 4 to 6 questions expected; these are the most frequently tested sub-topics in MAT
• Time, Speed and Distance — 3 to 4 questions including trains, boats and streams variants
• Time and Work — 2 to 3 questions including pipe and cistern problems
• Simple Interest and Compound Interest — 2 to 3 questions covering installment and half-yearly calculations
• Ratio, Proportion and Averages — 2 to 3 questions combined
• Mixtures and Alligations — 1 to 2 questions

Algebra — High Priority

• Arithmetic Progressions and Geometric Progressions — 2 to 3 questions
• Linear and Quadratic Equations — 2 to 3 questions
• Logarithms and Surds — 1 to 2 questions

Number System — Medium Priority

• HCF and LCM — 1 to 2 questions
• Divisibility Rules and Remainders — 1 to 2 questions
• Factors, Unit Digit Problems and Number Properties — 1 to 2 questions

Geometry and Mensuration — Medium Priority

• Triangles including similarity, congruence and Pythagoras theorem — 2 questions
• Circles, chords and angles — 1 to 2 questions
• Area and Volume of 2D and 3D figures — 2 to 3 questions

Modern Mathematics — Lower Priority but Scoring

• Permutation and Combination — 1 to 2 questions
• Probability — 1 to 2 questions
• Set Theory and Venn Diagrams — 1 question

Practice Tips for MAT September 2026 Mathematical Skills

A structured preparation approach can push your score from average to above 70 percentile. Students who attempt 28 to 32 questions with 85 to 90% accuracy consistently score above 70 percentile in MAT Mathematical Skills.

• Begin with Arithmetic — spend the first three to four weeks mastering Arithmetic sub-topics as these yield the highest return on study time given their 38 to 45% weightage
• Learn calculation shortcuts for multiplication, squares and percentage calculations to save 15 to 20 seconds per question
• Avoid random guessing — the -0.25 negative marking makes wild attempts costly; skip unfamiliar questions and return only if time allows
• Attempt 2 to 3 full-length MAT mock tests per week in the final four to six weeks before the exam to build speed and identify weak chapters
• Practice previous year MAT papers from 2022, 2023 and 2024 to recognise recurring question patterns and difficulty levels
• Cap time per question at 50 to 60 seconds — move to the next question if you cannot solve it within this limit
• Revise formulas daily — maintain a formula sheet and revise all key formulas at least once every three days in the final month
• Build accuracy before speed — aim for 90% accuracy on Arithmetic and Algebra questions before trying to increase your total attempt count
