📌 SSC Maths Syllabus (Chapter-wise)

1. Number System / Arithmetic

Integers, Fractions, LCM-HCF, Divisibility rules, Simplification

Important Formulas/Concepts:



BODMAS Rule

Divisibility test (2,3,4,5,8,9,11)

Rational & Irrational Numbers




---

2. Percentage

Basic calculation, increase/decrease, profit-loss, discount, marks, population problems

Formulas:

% = (Value / Total) × 100

Successive % Change =




---

3. Ratio & Proportion

Comparison, partnership, mixture problems

Formulas:

Ratio = a : b ⇒ a/b

Partnership: Profit ∝ (Investment × Time)




---

4. Average

Formula:

Average = (Sum of observations) / (Number of observations)




---

5. Algebra

Identities, equations, simplifications

Formulas:












---

6. Mensuration (2D & 3D Geometry)

Square, rectangle, triangle, circle, cone, sphere, cylinder, cuboid

Formulas:

Square area = , Perimeter =

Rectangle area = , Perimeter =

Triangle area =

Circle area = , Circumference =

Cone volume =

Cylinder volume =

Sphere volume =




---

7. Geometry

Lines, angles, triangles, circles, polygons

Important Points:

Sum of angles of triangle = 180°

Exterior angle of polygon = 360°/n

Area of equilateral triangle =




---

8. Trigonometry

Heights & distances, ratios & identities

Formulas:












---

9. Speed, Time & Distance

Relative speed, trains, boats-streams

Formulas:

Speed = Distance/Time

Relative speed (same direction) = v1 – v2

Relative speed (opposite) = v1 + v2

Boat in stream: Upstream = (u–v), Downstream = (u+v)




---

10. Simple Interest & Compound Interest

Formulas:

SI =

CI =




---

11. Profit, Loss & Discount

Formulas:

Profit = SP – CP

Loss = CP – SP

Profit% = (Profit/CP)×100

SP = CP × (100+Profit%)/100

SP = CP × (100–Loss%)/100




---

12. Time & Work / Pipes & Cisterns

Formulas:

Work = Rate × Time

If A can do a work in x days ⇒ 1 day work = 1/x

If A = x days, B = y days ⇒ Together = (xy)/(x+y)




---

13. Data Interpretation (DI)

Tables, bar graphs, pie charts

Needs % and ratio concepts



---

14. Miscellaneous (Simplification, Surds & Indices, Probability, Permutation & Combination)

Formulas:

Surds:

Probability = Favourable / Total cases

nPr = n! / (n–r)!

nCr = n! / (r!(n–r)!)
