Tips, tricks & guides to master speed math for competitive exams
Explore well-researched articles on mental math techniques, Vedic math shortcuts, speed calculation tricks, and exam strategies for SSC, IBPS, SBI, CAT and more. Whether you're a beginner or brushing up before an exam, our blog covers everything from basic arithmetic to advanced problem-solving patterns.
Average — also called mean — is one of the most frequently tested topics in every major competitive exam. SSC CGL, RRB NTPC, IBPS PO, and school-level examinations all include average problems in various forms: finding the mean of a data set, finding a missing value when the average is known, calculating weighted averages, and solving word problems involving changing averages.
Fractions appear in nearly every branch of mathematics — arithmetic, algebra, geometry, data interpretation, and probability. Yet for many students, simplifying fractions remains slow and uncertain. The standard approach of finding the HCF through repeated prime factorization works correctly but inefficiently, especially under exam time pressure.
Division is the arithmetic operation most people find slowest and most error-prone. Multiplication has dozens of well-known shortcuts — but division shortcuts are rarely taught systematically, leaving most students dependent on long division even when faster methods exist.
Vedic Mathematics is a system of mental calculation derived from ancient Indian scriptures called the Vedas. Rediscovered and compiled by Bharati Krishna Tirthaji in the early 20th century, it consists of 16 main sutras (formulas) and 13 sub-sutras that cover virtually every branch of arithmetic and algebra.
The RRB NTPC Computer Based Test contains 30 mathematics questions to be solved within a combined 90-minute window shared across three sections. In practice, strong candidates allocate roughly 25–30 minutes to the mathematics section — meaning each question must be answered in under 90 seconds on average.
The IBPS PO Preliminary examination contains 35 quantitative aptitude questions to be solved in 20 minutes — a pace of just 34 seconds per question. The Mains examination is more generous with time but significantly more complex, featuring data interpretation sets, data sufficiency, and higher-order arithmetic that demand both speed and analytical depth.
The SSC CGL Tier 1 examination gives you 60 minutes to answer 100 questions across four sections. The Quantitative Aptitude section contains 25 questions — meaning you have roughly 40 minutes if you allocate time equally, but in practice most candidates finish General Awareness quickly and redirect that time to Math and Reasoning.
Percentages are everywhere — in exam papers, bank interest calculations, discount offers, tax computations, salary hikes, and data interpretation tables. Yet for many students, percentage calculations remain slow, error-prone, and mentally exhausting.
In almost every competitive exam — SSC, IBPS, CAT, RRB, UPSC — squares of numbers appear repeatedly. They show up in simplification problems, geometry questions, algebra, data interpretation, and number series. A candidate who instantly knows that 67² = 4489 or 83² = 6889 has a measurable edge over someone who must work it out from scratch.
