What is the Exam?
The Air Force Common Admission Test, commonly known as AFCAT, is a national-level competitive examination conducted biannually by the Indian Air Force (IAF) to select officers for various branches, including Flying, Ground Duty (Technical), and Ground Duty (Non-Technical). As one of the most prestigious defence examinations in India, AFCAT attracts lakhs of dynamic graduates aspiring to serve the nation as commissioned officers.
The Numerical Ability section tests a candidate's basic mathematical aptitude, speed, and mental agility under time constraints. While the questions are generally of matriculation (Class 10) level, the challenge lies in solving them accurately within seconds. To conquer this section, candidates must master core quantitative concepts such as percentages, profit and loss, simple and compound interest, time and work, speed, distance, and time, along with algebra and mensuration formulas.

Syllabus 2026
The numerical ability section evaluates a candidate's competency across various arithmetical and advanced mathematical topics. Below is the detailed syllabus breakdown along with the AFCAT numerical ability important formulas required for each topic:
| Topic | Key Sub-Topics & Concepts | Essential Formulas |
|---|---|---|
| Number System | Divisibility rules, unit digit, factors, LCM & HCF | (LCM \times HCF = Product , of , two , numbers) |
| Percentages | Percentage change, successive percentage, population growth | (% , Change = \frac{Final - Initial}{Initial} \times 100) |
| Profit & Loss | SP, CP, Profit%, Loss%, Discount, Marked Price | (Profit% = \frac{SP - CP}{CP} \times 100), (SP = MP \times (1 - \frac{Discount%}{100})) |
| Simple & Compound Interest | SI, CI, difference between SI and CI for 2 years | (SI = \frac{P \times R \times T}{100}), (CI = P(1 + \frac{R}{100})^T - P) |
| Average | Arithmetic mean, weighted average, speed averages | (Average = \frac{Sum , of , Observations}{Number , of , Observations}) |
| Ratio & Proportion | Partnership, mixture and allegation, proportional divisions | (\frac{A}{B} = \frac{C}{D} \implies AD = BC) |
| Time & Work | Efficiency, pipes and cisterns, alternate days | (Work = Efficiency \times Time) |
| Time, Speed & Distance | Relative speed, trains, boats and streams | (Speed = \frac{Distance}{Time}), (Relative , Speed = S_1 \pm S_2) |
| Mensuration | Area and perimeter of 2D shapes, volume of 3D solids | Area of triangle = (\frac{1}{2} \times base \times height) |
Exam Pattern
The AFCAT question paper comprises four distinct sections: General Awareness, Verbal Ability in English, Numerical Ability, and Reasoning and Military Aptitude Test. For candidates applying to the Ground Duty (Technical) branch, an additional Engineering Knowledge Test (EKT) is conducted.
| Section | Number of Questions | Marks | Negative Marking |
|---|---|---|---|
| General Awareness | 25 | 75 | (-1) for incorrect |
| Verbal Ability in English | 30 | 90 | (-1) for incorrect |
| Numerical Ability | 20 | 60 | (-1) for incorrect |
| Reasoning & Military Aptitude | 25 | 75 | (-1) for incorrect |
| Total | 100 | 300 | - |
