Number System Formulas for SSC CGL

SSC CGL Number System questions mainly test basic properties of numbers, divisibility, factors, HCF, LCM, remainders and number calculations. These formulas also help in simplifying questions from other arithmetic chapters.

Basic divisibility rules

2: Last digit is even.

3: Sum of digits is divisible by 3.

4: Last two digits are divisible by 4.

5: Last digit is 0 or 5.

6: Number is divisible by both 2 and 3.

8: Last three digits are divisible by 8.

9: Sum of digits is divisible by 9.

10: Last digit is 0.

11: Difference between the sums of alternate digits is 0 or a multiple of 11.

HCF and LCM

Product of two positive integers = HCF × LCM

For two numbers a and b:

LCM(a, b) × HCF(a, b) = a × b

Sum of first n natural numbers

1 + 2 + 3 + … + n = n(n + 1)/2

Sum of first n odd numbers

1 + 3 + 5 + … + (2n – 1) = n^2

Sum of first n even numbers

2 + 4 + 6 + … + 2n = n(n + 1)

Sum of squares

1^2 + 2^2 + 3^2 + … + n^2 = n(n + 1)(2n + 1)/6

Sum of cubes

1^3 + 2^3 + 3^3 + … + n^3 = [n(n + 1)/2]^2

Percentage Formulas for SSC CGL

Percentage is one of the most useful topics in SSC CGL because it is directly used in Profit and Loss, Discount, Interest, Population, Data Interpretation and comparison questions.

Basic percentage

Percentage = (Part/Whole) × 100

Find a percentage of a number

x% of y = (x/100) × y

Percentage increase

Percentage Increase = (Increase/Original Value) × 100

Percentage decrease

Percentage Decrease = (Decrease/Original Value) × 100

New value after increase

New Value = Original Value × (1 + r/100)

New value after decrease

New Value = Original Value × (1 – r/100)

Successive percentage change

Net Change % = a + b + (ab/100)

Use b as negative when the second change is a decrease.

For an increase of a% followed by a decrease of b%:

Net Change % = a – b – (ab/100)

Population increase

New Population = Original Population × (1 + r/100)^n

Population decrease

New Population = Original Population × (1 – r/100)^n

Reverse percentage

If a number becomes X after an increase of r%:

Original Value = X × 100/(100 + r)

If a number becomes X after a decrease of r%:

Original Value = X × 100/(100 – r)

Ratio and Proportion Formulas for SSC CGL

SSC CGL Ratio compares two quantities, while proportion states that two ratios are equal.

Basic ratio

a:b = a/b

Equivalent ratio

a:b = ka:kb

Proportion

a:b = c:d

Therefore:

ad = bc

Fourth proportional

If a:b = c:x:

x = bc/a

Third proportional

If a:b = b:c:

b^2 = ac

Direct proportion

x1/x2 = y1/y2

Inverse proportion

x1/x2 = y2/y1

Componendo

If a/b = c/d:

(a + b)/b = (c + d)/d

Dividendo

If a/b = c/d:

(a – b)/b = (c – d)/d

Componendo and Dividendo

If a/b = c/d:

(a + b)/(a – b) = (c + d)/(c – d)

Average Formulas for SSC CGL

SSC CGL Average questions are generally based on total values and number of observations. The same formulas are useful for combined average and missing-value questions.

Basic average: Average = Sum of observations/Number of observations

Total when average is known: Sum = Average × Number of observations

Combined average: Combined Average = (n1A1 + n2A2)/(n1 + n2)

New average after adding one value: New Average = (nA + x)/(n + 1)

New average after removing one value: New Average = (nA – x)/(n – 1)

If average increases by d after adding one number: New Number = A + (n + 1)d

Weighted average: Weighted Average = Sum of (Weight × Value)/Sum of Weights

Profit and Loss Formulas for SSC CGL

SSC CGL Profit and Loss questions use Cost Price, Selling Price and percentage calculations. Keep the base of the percentage in mind: profit and loss percentage are calculated on Cost Price.

Profit: Profit = SP – CP

Loss: Loss = CP – SP

Profit percentage: Profit % = (Profit/CP) × 100

Loss percentage: Loss % = (Loss/CP) × 100

Selling Price at profit: SP = CP × (1 + Profit%/100)

Selling Price at loss: SP = CP × (1 – Loss%/100)

Cost Price at profit: CP = SP × 100/(100 + Profit%)

Cost Price at loss: CP = SP × 100/(100 – Loss%)

Marked Price and discount: Discount = MP – SP

Discount percentage: Discount % = (Discount/MP) × 100

Selling Price after discount: SP = MP × (1 – Discount%/100)

Successive discounts: Net Discount % = a + b – (ab/100)

For three successive discounts, apply the same idea step by step rather than adding all percentages directly.

Profit when selling price is known: Profit = SP – CP

Loss when selling price is known: Loss = CP – SP

Simple Interest Formulas for SSC CGL

Simple Interest is calculated only on the original Principal.

Simple Interest: SI = (P × R × T)/100

Amount: A = P + SI

Principal: P = (SI × 100)/(R × T)

Rate: R = (SI × 100)/(P × T)

Time: T = (SI × 100)/(P × R)

Where:

P = Principal

R = Rate per year

T = Time in years

Compound Interest Formulas for SSC CGL

Compound Interest is calculated on the amount accumulated during the previous periods.

Amount: A = P(1 + R/100)^n

Compound Interest: CI = A – P

Depreciation: A = P(1 – R/100)^n

Different compounding periods: For half-yearly compounding:

A = P(1 + R/200)^(2n)

For quarterly compounding:

A = P(1 + R/400)^(4n)

Difference between CI and SI for 2 years: CI – SI = P(R/100)^2

Partnership Formulas for SSC CGL

Partnership questions generally depend on the amount of capital invested and the time for which it remains invested.

Profit sharing ratio

Profit Share ∝ Capital × Time

For two partners

A:B = C1T1:C2T2

Where:

C1, C2 = Capitals

T1, T2 = Investment times

If capitals are equal

Profit ratio = Time ratio

If time is equal

Profit ratio = Capital ratio

Mixture and Alligation Formulas for SSC CGL

Alligation is used when two quantities with different prices or concentrations are mixed to obtain a required mean value.

Alligation ratio

Quantity of cheaper : Quantity of dearer = (Dearer Value – Mean Value) : (Mean Value – Cheaper Value)

Weighted average

Mean Value = Total Value/Total Quantity

For concentration questions, use the same alligation relationship by replacing price with concentration.

Time and Work Formulas for SSC CGL

Time and Work questions become easier when work done in one day is used instead of directly calculating total days.

Basic relationship

Work = Efficiency × Time

One day’s work

If A completes a work in x days:

One day’s work of A = 1/x

If B completes the work in y days

One day’s work of B = 1/y

A and B together

One day’s work = 1/x + 1/y

Time taken by A and B together

Time = xy/(x + y)

For three workers

One day’s work = 1/x + 1/y + 1/z

Efficiency and time

Efficiency Ratio = Inverse of Time Ratio

If:

A:B efficiency = m:n

Then:

A:B time = n:m

Work based on efficiency

Work = Men × Days × Hours × Efficiency

For the same amount of work:

M1D1H1E1 = M2D2H2E2

Pipes and Cisterns Formulas for SSC CGL

Pipes and Cisterns questions use the same basic idea as Time and Work.

Filling pipe

If a pipe fills a tank in x hours:

One hour’s work = 1/x

Emptying pipe

If a pipe empties the tank in y hours:

One hour’s work = -1/y

Combined work

Net work per hour = Sum of filling rates – Sum of emptying rates

Time to fill the tank

Time = 1/(Net work per hour)

Time, Speed and Distance Formulas for SSC CGL

These formulas are used in basic speed questions, trains, relative speed, boats and streams.

Basic formula

Speed = Distance/Time

Distance = Speed × Time

Time = Distance/Speed

Conversion

1 m/s = 18/5 km/h

1 km/h = 5/18 m/s

Average speed

Average Speed = Total Distance/Total Time

Average speed for equal distances

Average Speed = 2xy/(x + y)

Relative speed in same direction

Relative Speed = x – y

Relative speed in opposite directions

Relative Speed = x + y

Trains Formulas for SSC CGL

SSC CGL Train questions are usually based on relative speed and total distance covered while crossing an object or another train.

Train crossing a pole or standing person

Time = Length of Train/Speed

Train crossing a platform

Time = (Length of Train + Length of Platform)/Speed

Two trains crossing in opposite directions

Time = (L1 + L2)/(S1 + S2)

Two trains moving in the same direction

Time = (L1 + L2)/|S1 – S2|

Boats and Streams Formulas for SSC CGL

SSC CGL Boats and Streams questions compare the boat’s speed in still water with the stream’s speed.

Downstream speed

Downstream Speed = Boat Speed + Stream Speed

Upstream speed

Upstream Speed = Boat Speed – Stream Speed

Boat speed in still water

Boat Speed = (Downstream Speed + Upstream Speed)/2

Stream speed

Stream Speed = (Downstream Speed – Upstream Speed)/2

Problems on Ages Formulas for SSC CGL

SSC CGL Age questions mainly depend on the fact that the age difference between two people remains constant.

Present age after n years

Future Age = Present Age + n

Present age n years ago

Past Age = Present Age – n

Age difference

Age Difference = Older Age – Younger Age

Sum of ages after n years

New Sum = Present Sum + Number of Persons × n

Sum of ages n years ago

Past Sum = Present Sum – Number of Persons × n

Algebra Formulas for SSC CGL

Algebraic identities are among the most useful maths formulas for SSC CGL because the same identities can be applied directly in simplification and algebra-based questions.

Square of a sum

(a + b)^2 = a^2 + 2ab + b^2

Square of a difference

(a – b)^2 = a^2 – 2ab + b^2

Difference of squares

a^2 – b^2 = (a – b)(a + b)

Cube of a sum

(a + b)^3 = a^3 + b^3 + 3ab(a + b)

Cube of a difference

(a – b)^3 = a^3 – b^3 – 3ab(a – b)

Sum of cubes

a^3 + b^3 = (a + b)(a^2 – ab + b^2)

Difference of cubes

a^3 – b^3 = (a – b)(a^2 + ab + b^2)

Square of three terms

(a + b + c)^2 = a^2 + b^2 + c^2 + 2ab + 2bc + 2ca

Special identity

If a + b + c = 0:

a^3 + b^3 + c^3 = 3abc

Useful identity

(a + b)^2 = (a – b)^2 + 4ab

Another useful identity

(a – b)^2 = (a + b)^2 – 4ab

Algebraic Surds Formulas

The SSC CGL syllabus includes elementary surds, so basic rules should be revised.

sqrt(a) × sqrt(b) = sqrt(ab)

sqrt(a)/sqrt(b) = sqrt(a/b)

sqrt(a^2) = a, for a >= 0

1/sqrt(a) = sqrt(a)/a

(a + sqrt(b))(a – sqrt(b)) = a^2 – b

Linear Equation

For:

ax + b = c

x = (c – b)/a

Quadratic Equation

For:

ax^2 + bx + c = 0

x = [-b ± sqrt(b^2 – 4ac)]/(2a)

Geometry Formulas for SSC CGL

Geometry questions in SSC CGL cover triangles, circles, chords, tangents, similarity, congruence and related properties. The formulas are useful, but the properties and theorems must also be revised.

Triangle Formulas

Angle sum

A + B + C = 180°

Area of triangle

Area = 1/2 × Base × Height

Perimeter

Perimeter = a + b + c

Pythagoras theorem

Hypotenuse^2 = Base^2 + Perpendicular^2

Equilateral triangle area

Area = (sqrt(3)/4) × a^2

Equilateral triangle height

Height = (sqrt(3)/2) × a

Heron’s formula

s = (a + b + c)/2

Area = sqrt[s(s – a)(s – b)(s – c)]

Similar Triangles

If two triangles are similar:

Corresponding sides are proportional.

Area Ratio = (Corresponding Side Ratio)^2

Perimeter = πr + 2r

Area of quadrant

Area = πr^2/4

Length of quadrant arc

Arc Length = πr/2

Important Circle Properties

Radius is perpendicular to the tangent at the point of contact.

Tangents from the same external point are equal.

Equal chords subtend equal angles at the centre.

The perpendicular from the centre to a chord bisects the chord.

The angle in a semicircle is 90°.

Mensuration Formulas for SSC CGL

Mensuration is an important part of the SSC CGL Maths syllabus. Revise both 2D and 3D formulas because questions may ask area, perimeter, curved surface area, total surface area or volume.

Trigonometry Formulas for SSC CGL

SSC CGL Trigonometry is included in both the Tier-I and Tier-II syllabus. Focus on trigonometric ratios, standard angles, identities, complementary angles and simple Height and Distance questions.

Basic Trigonometric Ratios

sin θ = Perpendicular/Hypotenuse

cos θ = Base/Hypotenuse

tan θ = Perpendicular/Base

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Trigonometric Identities

sin^2 θ + cos^2 θ = 1

1 + tan^2 θ = sec^2 θ

1 + cot^2 θ = cosec^2 θ

tan θ = sin θ/cos θ

cot θ = cos θ/sin θ

Complementary Angles

sin(90° – θ) = cos θ

cos(90° – θ) = sin θ

tan(90° – θ) = cot θ

cot(90° – θ) = tan θ

sec(90° – θ) = cosec θ

cosec(90° – θ) = sec θ

Standard Trigonometric Values

Angle	sin θ	cos θ	tan θ
0°	0	1	0
30°	1/2	sqrt(3)/2	1/sqrt(3)
45°	1/sqrt(2)	1/sqrt(2)	1
60°	sqrt(3)/2	1/2	sqrt(3)
90°	1	0	Not defined

Height and Distance

For a right triangle:

tan θ = Height/Base

Therefore:

Height = Base × tan θ

Base = Height/tan θ

For a right triangle:

Hypotenuse^2 = Base^2 + Height^2

Statistics Formulas for SSC CGL

SSC CGL Tier-II Mathematical Abilities includes measures such as mean, median, mode and standard deviation. Basic statistics formulas should therefore be part of your SSC CGL maths formula sheet.

Arithmetic mean

Mean = Sum of observations/Number of observations

Mean for frequency distribution

Mean = Sum(fx)/Sum(f)

Weighted mean

Weighted Mean = Sum(wx)/Sum(w)

Median for ungrouped data

Median = Middle observation after arranging the data.

For an odd number of observations:

Median = ((n + 1)/2)th observation

For an even number of observations:

Median = Average of the (n/2)th and ((n/2) + 1)th observations

Mode

Mode = Observation occurring most frequently

Range

Range = Maximum Value – Minimum Value

Population standard deviation

SD = sqrt[Sum(x – mean)^2/n]

For a frequency distribution:

SD = sqrt[Sum f(x – mean)^2 / Sum f]

Probability Formulas for SSC CGL

The SSC CGL 2026 Tier-II syllabus includes simple probability. Focus on basic probability rather than complex probability methods.

Basic probability

P(E) = Number of favourable outcomes/Total number of possible outcomes

Complement

P(not E) = 1 – P(E)

Probability of impossible event

P(E) = 0

Probability of certain event

P(E) = 1

Addition rule

P(A or B) = P(A) + P(B) – P(A and B)

For mutually exclusive events

P(A or B) = P(A) + P(B)

Multiplication rule for independent events

P(A and B) = P(A) × P(B)

Data Interpretation Formulas for SSC CGL

SSC CGL Data Interpretation mainly tests whether you can read tables and graphs quickly and apply basic arithmetic correctly. The formulas are usually simple, but calculation speed matters.

Percentage from data

Percentage = (Part/Total) × 100

Percentage change

Percentage Change = (New Value – Old Value)/Old Value × 100

Pie chart angle

Angle = (Value/Total Value) × 360°

Value from pie chart

Value = (Angle/360°) × Total Value

Average from data

Average = Sum of Values/Number of Values

Ratio from data

Ratio = First Value/Second Value

For DI, revise Percentage, Ratio, Average, Profit and Loss and basic arithmetic together because those formulas are frequently used while interpreting the data.

Extra SSC CGL Maths Formula Topics for Quick Revision

Some commonly circulated SSC Maths formula sheets include topics that are not separately listed in the SSC CGL 2026 Quantitative Aptitude syllabus. These formulas can still be useful for broader competitive-exam practice, but they should not replace the topics explicitly mentioned in the current CGL syllabus.

Permutation and Combination

Factorial

n! = n × (n – 1) × (n – 2) × … × 1

Permutation

nPr = n!/(n – r)!

Combination

nCr = n!/[r!(n – r)!]

Relation

nCr = nC(n – r)

SSC CGL Maths Tricks for Faster Calculation

SSC CGL maths tricks are most useful when they reduce calculation without changing the basic method. Learn a small number of reliable shortcuts and practise them repeatedly instead of memorising many tricks without knowing when to use them.

Multiplication by 11

For a two-digit number ab:

ab × 11 = a(a + b)b

Example:

43 × 11 = 473

For 52 × 11:

5 + 2 = 7

Answer = 572

Multiplication by 99

n × 99 = n × (100 – 1)

Example:

45 × 99 = 45 × 100 – 45 = 4455

Multiplication by 999

n × 999 = n × (1000 – 1)

Example:

654 × 999 = 654000 – 654 = 653346

Squaring a Number Ending in 5

For a number n5:

(n5)^2 = n × (n + 1) followed by 25

Example:

35^2 = 3 × 4 followed by 25 = 1225

Squaring Numbers Near 100

For:

(100 – a)^2 = 10000 – 200a + a^2

Example:

98^2 = 10000 – 400 + 4 = 9604

Percentage Shortcut

10% of a number = Divide by 10

5% = Half of 10%

20% = Double of 10%

25% = One-fourth

50% = One-half

75% = Three-fourths

Fraction to Percentage Conversions

1/2 = 50%

1/3 = 33 1/3%

2/3 = 66 2/3%

1/4 = 25%

3/4 = 75%

1/5 = 20%

2/5 = 40%

3/5 = 60%

4/5 = 80%

1/6 = 16 2/3%

5/6 = 83 1/3%

1/8 = 12.5%

3/8 = 37.5%

5/8 = 62.5%

7/8 = 87.5%

1/10 = 10%

1/12 = 8 1/3%

Basic Calculation Revision

Before the exam, revise:

• Multiplication tables up to 20 or 25
• Squares up to 50
• Cubes up to 20
• Common fraction-percentage conversions
• Basic algebraic identities
• Standard trigonometric values

These calculations are not separate formulas, but they can reduce the time spent on direct questions.

How Many Maths Formulas Are Important for SSC CGL?

There is no official number of formulas that SSC asks candidates to memorise. The Commission specifies topics and concepts in the SSC CGL syllabus, not a fixed formula count.

Instead of trying to memorise hundreds of formulas separately, learn the formulas that are repeatedly used in different question types. For example, Percentage is used in Profit and Loss, Discount, Interest, Population and Data Interpretation questions.

The SSC CGL maths formula sheet below covers the major formulas needed for the official SSC CGL Mathematics syllabus, along with a few useful extra formulas and shortcuts for revision.

How to Memorize SSC CGL Maths Formulas

Do not try to memorise the entire SSC CGL maths formula sheet in one sitting. Formula retention improves when formulas are attached to the type of question in which they are used.

Use this method:

1. Learn 5-10 formulas from one topic.
2. Solve 10-15 questions using those formulas.
3. Mark the formulas you forgot.
4. Revise them again the same day.
5. Revisit them after 2-3 days.
6. Use PYQs to check whether you can identify the correct formula quickly.
7. Add repeatedly forgotten formulas to a one-page revision sheet.

For example, do not memorise the Time and Work formulas alone. Solve questions on two people working together, efficiency comparison and work completed in different numbers of days. The formula then becomes easier to remember.

How to Use SSC CGL Maths Formulas in the Exam

Knowing maths formulas for SSC CGL is not enough. You must also know which formula fits the question.

Before solving, identify:

• What is given?
• What is being asked?
• Which quantities are related?
• Which formula connects those quantities?
• Can the calculation be simplified?

Do not force a shortcut when the normal method is shorter. A shortcut is useful only when it saves time and does not increase the chance of a mistake.

The 2026 SSC CGL Tier-I Quantitative Aptitude section has a 15-minute sectional timer, so calculation speed matters. In Tier-II, the Mathematical Abilities section also has a separate 30-minute sectional timer. Practise formulas with a timer so that recall becomes faster under exam conditions.

Common Mistakes While Using SSC CGL Maths Formulas

Memorising an SSC CGL  formula without understanding its variables is one of the most common mistakes. Candidates should also be careful about units, percentage bases and signs.

Avoid these errors:

• Using Profit % on Selling Price instead of Cost Price
• Using Discount % on Selling Price instead of Marked Price
• Forgetting to convert km/h into m/s
• Using ordinary average when weighted average is required
• Adding successive percentage changes directly
• Forgetting that efficiency and time are inversely proportional
• Using the wrong train relative speed
• Confusing Curved Surface Area with Total Surface Area
• Using diameter in a formula that requires radius
• Forgetting the square on radius in area formulas
• Mixing degrees and radians
• Using the wrong trigonometric ratio
• Ignoring the frequency while calculating mean
• Repeating a formula when the question can be solved with a simpler method

Conclusion

SSC CGL Maths Formulas 2026 should be treated as a quick-revision tool that works alongside concepts, PYQs and timed practice. The latest SSC CGL syllabus covers a wide range of Arithmetic and Advanced Maths topics, so candidates should organise formulas chapter-wise instead of trying to memorise them randomly.

Start with Percentage, Ratio, Average, Profit and Loss, Interest, Time and Work and Time, Speed and Distance. Then revise Algebra, Geometry, Mensuration and Trigonometry, followed by Statistics, Probability and Data Interpretation. Use SSC CGL Maths Short Tricks only where they genuinely save time. Candidates can also use PracticeMock for regular practice and timed tests to apply these formulas.

Keep the complete formula sheet available during revision, solve questions immediately after learning a formula and repeatedly revisit the formulas you forget. This approach makes the maths formulas for SSC CGL easier to remember and easier to apply under the sectional time limits of the examination.

SSC CGL Maths Formulas FAQs

What are the most important maths formulas for SSC CGL?

The most important maths formulas for SSC CGL come from Percentage, Ratio and Proportion, Average, Profit and Loss, Discount, Simple and Compound Interest, Time and Work, Time and Distance, Algebra, Geometry, Mensuration and Trigonometry. For Tier-II, also revise Statistics, Probability and data-based formulas.

Where can I find the SSC CGL Maths Formulas PDF?

The SSC CGL Maths Formulas PDF in this article is designed for quick revision of the major formulas used in the Quantitative Aptitude and Mathematical Abilities syllabus. Candidates can keep the PDF on their phone or computer and use it for repeated revision before sectional tests, previous year papers and full-length mocks.

Are SSC CGL Maths Short Tricks important?

SSC CGL Maths Short Tricks can save time in calculation-heavy questions, especially when the method is simple and reliable. However, candidates should first understand the basic concept and standard formula. A shortcut should be used only when it reduces calculation time without increasing the chance of a wrong answer.

How should I memorize maths formulas for SSC CGL?

Memorise SSC CGL formulas topic-wise and immediately use them in practice questions. Revise a small group of formulas on the same day, again after 2-3 days, and then during weekly revision. PYQs are especially useful because they show when a particular formula should be applied.

How many formulas should I learn for SSC CGL Maths?

SSC does not prescribe a fixed number of formulas. Instead, candidates should learn the formulas needed for the topics mentioned in the official syllabus. A well-organised SSC CGL maths formula sheet covering Arithmetic, Algebra, Geometry, Mensuration, Trigonometry, Statistics and Probability is more useful than trying to memorise an arbitrary number of formulas.

Which formulas should I revise first for SSC CGL Maths?

Start with Percentage, Ratio, Average, Profit and Loss, Discount, SI and CI, Time and Work, Time and Distance, Algebraic Identities, Geometry, Mensuration and Trigonometry. These formulas support a large part of the arithmetic and advanced mathematics preparation and are useful for both speed building and revision.

Can I prepare SSC CGL Maths only through formulas?

No. Formulas are a revision tool, not a complete SSC CGL preparation method. Candidates also need concept clarity, previous year questions, calculation practice, timed tests and mock-test analysis. A formula is useful only when you know what the variables mean and when the formula should be applied.

What is the SSC CGL Maths syllabus for 2026?

The SSC CGL 2026 Quantitative Aptitude syllabus includes Number System, Percentage, Ratio and Proportion, Square Roots, Average, Interest, Profit and Loss, Discount, Partnership, Mixture and Alligation, Time and Distance, Time and Work, Algebra, Geometry, Mensuration, Trigonometry and statistical charts. Tier-II additionally specifies statistics and simple probability.
