Complete SSC Maths Formula Guide for Competitive Exams

Mathematics is one of the most important and scoring subjects in government competitive examinations. Exams such as SSC GD, Railway (RRB), SI, Police Constable, Delhi Police and many other state-level exams include a compulsory Maths section.

Most aspirants fail to score well in Maths not because the syllabus is difficult, but because they do not revise formulas properly or lack structured notes. This detailed guide by NotesLover.com is designed to solve exactly that problem.

SSC Maths Syllabus Overview

SSC and Railway Maths syllabus mainly includes Arithmetic, Geometry, Mensuration, Trigonometry and Data Interpretation.

1. Arithmetic - Backbone of SSC Maths

Arithmetic contributes nearly 40-50% of the total Maths questions in SSC GD and Railway exams.

Percentages

• Percentage = (Part / Whole) × 100
• x% = x / 100
• Increase or Decrease % = (Change / Original) × 100

Profit & Loss

• Profit = SP − CP
• Loss = CP − SP
• Profit % = (Profit / CP) × 100
• Loss % = (Loss / CP) × 100

Simple Interest

• SI = (P × R × T) / 100
• Amount = P + SI

Time & Work

• If a person completes work in x days, 1 day work = 1/x
• Combined work = 1/A + 1/B

2. Geometry

Geometry is highly scoring if concepts are clear.

Triangles

• Sum of angles = 180°
• Area = ½ × base × height
• Pythagoras theorem: a² + b² = c²

Circles

• Circumference = 2πr
• Area = πr²

3. Mensuration

• Cube Volume = a³
• Cylinder Volume = πr²h
• Sphere Volume = 4/3 πr³

4. Trigonometry
