CLAT Quantitative Techniques 2027: Topics, Formulas and Preparation

Content Curator | Updated On - Oct 7, 2026

CLAT Quantitative Techniques tests how you use numbers inside a short data set. The 2027 UG paper assigns it approximately 10–14 questions, or 10% of the paper. The prescribed maths level is Class 10, not advanced Class 12 Mathematics.

Start with ratios, algebra, mensuration and statistical estimation. Then practise choosing the right figures and comparison from a paragraph or table. Knowing a formula is useful only when you know which quantity belongs in its denominator.

CLAT Quantitative Techniques Topics and Weightage

Topic	Skill to practise
Ratios and proportions	Split a total, compare quantities and scale a relationship
Basic algebra	Represent an unknown and solve the relationship in the data
Mensuration	Calculate lengths, areas or volumes with consistent units
Statistical estimation	Read numerical summaries and make the requested estimate
Numerical passages	Extract relevant figures before choosing an operation

The section uses short sets of numerical facts followed by linked questions. You may need to derive a missing value before answering the next question. The Consortium does not publish chapter-wise percentages, so a fixed claim such as “five percentage questions” is not a 2027 rule.

The subject range is approximate. It does not mean every paper must have exactly 12 maths questions or that the largest value in every subject range can occur together.

Build the Calculation Before Using a Formula

Calculation	Formula
Percentage of a total	Part / total × 100
Percentage increase	(New - old) / old × 100
Ratio a:b with total T	Shares are Ta/(a+b) and Tb/(a+b)
Simple average	Sum of observations / number of observations
Rectangle area	Length × breadth; use the same length unit
Weighted average	Total of value × frequency / total frequency

For a percentage question, write the comparison in words first: “out of all students”, “more than last year”, or “as a share of the second group”. These phrases choose the denominator. If 60 students belong to one club and 90 to another, the first club is 40% of the combined 150, but about 66.67% of the second club.

Keep units beside values while solving. A room measured in metres and a tile measured in centimetres cannot be compared directly in an area calculation. Convert the length units first, then square or multiply. Do not round an intermediate ratio if the final options are close.

Worked Data Set: Ratio, Percentage and Average

Original practice example: a library issued 240 books in April. Fiction and non-fiction were in the ratio 3:2. In May, fiction issues increased by 25%, while non-fiction issues fell by 12.5%.

Question	Calculation	Answer
April fiction issues	240 × 3/5	144
April non-fiction issues	240 × 2/5	96
May fiction issues	144 × 1.25	180
May non-fiction issues	96 × 0.875	84
Change in total issues	(264 - 240) / 240 × 100	10% increase
Average monthly fiction issues	(144 + 180) / 2	162

The two percentage changes use different bases. Adding 25% and -12.5%, then calling the result a 12.5% total increase, gives the wrong answer. Find the changed quantities before calculating the overall change.

This set also shows why the first calculation matters. An incorrect split of the April total carries into every later answer. Check that 144 + 96 returns the original 240 before moving on.

A Quantitative Practice Session That Finds the Weakness

Solve one numerical set without a timer. Underline the requested quantity and write the relevant data.
Check the answers, then label each error: extraction, operation, units or arithmetic.
Repair only the failed operation with a few short calculations.
Attempt a fresh set using the same operation with different figures.
Add timing after the method works; include answer recording in the measured time.

A student who can calculate 20% quickly but repeatedly chooses the wrong base needs comparison questions, not another speed-arithmetic sheet. Conversely, if the setup is correct and multiplication is slow, shorter calculation drills target the actual delay.

Use a dated paper from the CLAT question-paper archive to see numerical sets in a complete exam. Keep older paper totals separate from the current 120-question format.

How to Review a Low Quant Score

Error seen in the attempt	Repair task
Copied a figure from the wrong group	Make a two-column list of group and value before calculating
Used new value as the increase base	Write change divided by original value
Averaged percentages with unequal groups	Calculate the weighted total first
Mixed length and area units	Convert lengths before calculating area
One early error spoiled a whole set	Check the starting total or ratio before proceeding

With +1 for a correct answer and -0.25 for a wrong answer, eight correct and two wrong answers give 7.5 marks. Changing one wrong answer to correct adds 1.25 marks: the deduction disappears and a correct-answer mark is added. This is a calculation example, not a section cutoff.

Do not set a universal “safe” maths score. Final admission depends on the complete paper, rank, category and the applicable NLU allocation.

Choose Maths Material for the Right Job

Use Class 10-level material to repair a weak operation, then move to numerical sets that require reading and selecting data. A chapter exercise and a CLAT set solve different preparation problems.

The CLAT 2024 paper offers a historical 120-question paper for full-paper practice. When reviewing any paper, use its matching key and account for withdrawn questions rather than assuming every printed question contributes to the final score.

A useful explanation should show the data chosen, the operation and the arithmetic. If it only gives an option letter, it cannot reveal why your setup failed.

Total growth is 24/240 × 100 = 10%. The 25% fiction increase and 12.5% non-fiction decrease must be applied to their own starting quantities.

From Untimed Work to a Timed Set

Identify what the question compares.
List only the relevant figures and units.
Solve and check the starting total.
Classify the error before choosing another exercise.
Retest on fresh figures, then measure time.

Common Calculation Traps

−

Trap	Correction
Part versus whole	Name the denominator before substituting
Percentage change	Use the original quantity as the base
Unequal group sizes	Use a weighted calculation
Area conversions	Convert lengths before multiplying
Rounding too early	Keep exact fractions until the final step

CLAT Quantitative Techniques 2027 FAQs

Maths Level and Practice

Can a student without Class 12 Mathematics prepare for this section?+

Yes. The prescribed operations are at Class 10 level. A student who has not taken Mathematics in Class 12 can work on the stated foundations and numerical passages. Entrance-section preparation and the eligibility rules of a particular degree programme are separate matters.

Is Quantitative Techniques always exactly 12 questions?+

No. The 2027 format gives an approximate range of 10–14 questions. Twelve may describe a particular past paper, not a fixed future allocation.

Should I finish every arithmetic chapter before solving a CLAT set?+

No. Try a short set early. If the difficulty is a ratio split, repair ratios and return to a fresh set. If the calculation is familiar but the wrong values were selected, work on reading the data rather than postponing all passage practice.

Can I average two percentage changes to find the total change?+

Only when the underlying bases make that calculation valid. In the library example, fiction and non-fiction start at different values. Calculate each new value, add them and compare the new total with the old total.

Does 10% weightage make the section optional?+

It remains one of the five UG subjects. The approximate share describes the paper, not an exemption. How many questions you attempt depends on the set and your judgement within the full test duration.

Is a high Quant score enough for admission?+

No. CLAT admission is not based on the maths section alone. It contributes to the overall entrance score; allocation also depends on rank, preferences, category and the relevant seats.
