SSC CGL Quantitative Aptitude Notes — Free PDF Download

Quantitative Aptitude is one of the most scoring yet feared sections in the SSC CGL exam. With the right notes, formulas, and shortcuts, it can become your strongest section. Sikhami provides free, topic-wise Quantitative Aptitude notes designed specifically for SSC CGL aspirants.

Topics Covered in SSC CGL Quant Section

The SSC CGL Quantitative Aptitude section tests your mathematical ability and problem-solving skills. Here are the key topics you must prepare:

Number System

The foundation of Quant. Topics include divisibility rules, HCF & LCM, remainder theorems, and properties of numbers. Sikhami’s notes cover all shortcuts for finding HCF and LCM quickly, division tricks, and frequently asked number system questions in SSC CGL.

Percentage

One of the most frequently tested topics. You need to know fraction-to-percentage conversions (1/3 = 33.33%, 1/7 = 14.28%, etc.) by heart. Sikhami’s percentage notes include all standard conversions, shortcut methods for percentage change problems, and SSC CGL-specific question patterns.

Profit, Loss & Discount

This topic appears in almost every SSC CGL exam. Key concepts include cost price, selling price, markup, successive discounts, and dishonest dealer problems. Sikhami provides formula sheets and shortcut tricks for solving profit-loss questions in under 30 seconds.

Simple & Compound Interest

Understand the difference, learn the formulas, and practice with real SSC CGL previous year questions. Sikhami’s notes break down SI and CI into simple steps with solved examples.

Ratio, Proportion & Partnership

Covers ratio comparison, mixture problems, and partnership profit distribution. These questions are straightforward if you know the concepts well. Our notes include the alligation method and other quick-solving techniques.

Time, Speed & Distance

One of the trickier topics. Includes trains, boats & streams, and relative speed problems. Sikhami’s notes provide a formula chart and 10+ shortcut methods specifically useful for SSC CGL level questions.

Time & Work

Pipes and cisterns, efficiency-based problems, and work equivalence. Learn the LCM method which makes time & work problems significantly easier. Detailed notes available on Sikhami.

Geometry

Triangles, circles, quadrilaterals — geometry is a high-weightage topic in SSC CGL. You need to memorize key theorems and properties. Sikhami’s geometry notes include visual diagrams and all important theorems with their applications in SSC CGL questions.

Mensuration

Area and volume formulas for 2D and 3D figures. This topic is formula-heavy but very scoring if you’ve memorized the formulas. Download the complete mensuration formula sheet on Sikhami.

Trigonometry

Heights and distances, trigonometric identities, and standard angle values. SSC CGL typically asks 3–4 trigonometry questions. Sikhami’s notes cover all identities with trick-based solutions.

Algebra

Algebraic identities, simplification, and factorization. Learn key identities like (a+b)³, (a-b)³, a³+b³, and their applications. Available in Sikhami’s algebra notes with SSC CGL-specific examples.

Data Interpretation

Bar graphs, pie charts, tables, and line graphs. DI questions test your calculation speed more than concepts. Practice with Sikhami’s DI quizzes to build speed.

SSC CGL Quant Preparation Tips

Start with basics. If your fundamentals in Percentage, Ratio, and Number System are strong, advanced topics become much easier.

Memorize key formulas and conversions. There’s no shortcut to this — you must know fraction-percentage conversions, area/volume formulas, and trigonometric values by heart.

Practice with a timer. SSC CGL gives you less than a minute per question. Speed matters as much as accuracy.

Focus on high-weightage topics. Geometry, Mensuration, and Algebra together account for nearly 40% of the Quant section. Don’t skip them.

Solve previous year papers. SSC often repeats question patterns. Sikhami has PYQ-based quizzes to help you practice.
