The Quantitative Techniques section is the most mishandled section in all of CLAT preparation. Some aspirants ignore it entirely — “it is only 10 questions, it cannot matter that much.” Others spend months drilling advanced mathematics that never appears in the exam. Both approaches are costly mistakes.
Here is the reality: CLAT Quantitative Techniques topics are tested at Class 10 level, entirely through passage-based questions — and in a paper where the margin between rank 100 and rank 300 is often two to three marks, this 10–14 question section is anything but negligible. A student who masters the ten topics in this guide and attempts them accurately can gain a meaningful rank advantage over the majority of aspirants who treat QT as an afterthought.
This guide covers the 10 most tested CLAT Quantitative Techniques topics, what each one looks like in the actual exam, the formulas you need, and a section-level strategy to maximise your score without losing time you cannot spare.
CLAT Quantitative Techniques: Section Overview
Before covering the ten topics, here is what the section actually looks like in CLAT 2027:
| Feature | Details |
| Number of questions | 10–14 (approximately 10% of the paper) |
| Format | Passage-based MCQs — numerical data in text, tables, or graphs |
| Difficulty level | Class 10 standard — no advanced mathematics |
| Negative marking | −0.25 per wrong answer |
| Skills tested | Data interpretation, arithmetic application, percentage and ratio reasoning |
| Time to allocate | 10–12 minutes |
The Quantitative section includes arithmetic and data-based topics like Percentages, Ratios, Profit & Loss, Averages, Data Interpretation, Time & Work, and Mensuration. All questions are passage-based — numerical information is presented in a short paragraph or table, followed by questions that ask you to derive, calculate, or infer from that data.
From 2020 to 2026, questions from Percentage and Ratio topics appeared every single year, sometimes forming the majority of the section. In CLAT 2024, 2025, and 2026, around 12 questions were mainly based on Percentage and Ratio alone. This tells you exactly where to concentrate your preparation.
CLAT Quantitative Techniques Topics: The 10 You Cannot Skip
Topic 1: Percentages
Frequency: Extremely high — appears in every CLAT paper, every year without exception.
Percentages are the single most important topic in the entire CLAT Quantitative Techniques section. Percentages form the backbone of most CLAT maths important topics. They appear in standalone problems as well as embedded in Data Interpretation sets, covering percentage change, conversion of fractions and decimals to percentages, and questions on population growth, discounts, and data comparisons.
What CLAT tests: Percentage increase and decrease, percentage of a total, converting fractions to percentages, comparing two quantities as a percentage of each other, and percentage-based data interpretation from tables or graphs.
Key formulas to know:
- Percentage change = (New Value − Old Value) / Old Value × 100
- X% of Y = (X/100) × Y
- If A is X% more than B, then B is [X/(100+X)] × 100% less than A
How it appears in the paper: A passage describing two groups (men and women, two companies, two years) with different numerical values, followed by questions asking you to find percentage difference, percentage share, or percentage growth. The Oxfam India discrimination report passage is a classic example — presenting average earnings for men and women, then asking percentage gap calculations.
Preparation tip: Master fraction-to-percentage conversions (1/3 = 33.33%, 1/4 = 25%, 1/5 = 20%, 1/6 = 16.67%, 1/8 = 12.5%). These allow mental calculation without a pen during the exam, saving critical seconds.
Topic 2: Ratios and Proportions
Frequency: Extremely high — co-dominates the section alongside percentages.
Ratios and Proportions are the second pillar of CLAT QT. Ratios and Proportions cover calculating ratios, proportions, and relationships that are used to solve various problems related to finance and business. In practice, CLAT passages present data in ratio format and ask you to derive actual values, compare shares, or track changes over time.
What CLAT tests: Simplifying ratios, finding missing values in proportional relationships, combining ratios (A:B and B:C → A:B:C), and interpreting ratio-based data from passages.
Key formulas to know:
- If A:B = m:n, then A = m/(m+n) × Total and B = n/(m+n) × Total
- Compound ratio of a:b and c:d = ac:bd
- Proportion: a/b = c/d → a×d = b×c (cross multiplication)
How it appears in the paper: A passage describing the distribution of budget, workforce, or resources between two or more categories in ratio form, followed by questions asking you to find the actual value of one category given the total or another category’s value.
Preparation tip: Always read ratio questions fully before calculating. CLAT ratio questions frequently embed the total or one component’s value in the passage text — students who rush miss the given value and over-calculate.
Topic 3: Data Interpretation — Tables
Frequency: Very high — at least one table-based DI set in almost every CLAT paper.
Data Interpretation from tables is the most direct test of your ability to extract numbers from structured data and apply basic arithmetic operations under time pressure.
What CLAT tests: Reading two-variable tables (year vs category, product vs region, age group vs population), calculating totals, finding differences, computing percentage shares, and identifying trends across rows and columns.
How it appears in the paper: A table with 3–5 rows and 3–5 columns, followed by 3–4 questions. Questions typically ask for a total, a difference, a percentage of the total, or the highest/lowest value.
Preparation tip: When you encounter a table, spend 20–30 seconds scanning it fully before reading the questions — understand what the rows, columns, and units represent. Students who jump directly to questions without understanding the table structure waste time re-reading it for every question.
Common trap: Unit mismatches. CLAT QT tables frequently use values in thousands or lakhs without stating it prominently. Check the table header and footnotes carefully before calculating.
Topic 4: Data Interpretation — Bar Graphs and Pie Charts
Frequency: High — graphical DI appears in most CLAT papers, alternating between bar graphs and pie charts across sections.
What CLAT tests: Reading bar heights accurately, comparing bars across categories, computing percentages from pie chart segments, and combining graph data with calculation.
How it appears in the paper: A bar graph showing sales, population, or budget data across years or categories, with 2–3 questions asking for totals, differences, or percentage comparisons. Pie charts typically show proportional distribution with percentage values or actual values marked.
Preparation tip: For bar graphs, train your eye to estimate values quickly — you will rarely need to calculate exactly to the decimal to identify the right answer. The answer choices are usually spaced far enough apart that a close approximation is sufficient. For pie charts, know that a segment showing X% of a total T = (X/100) × T — this one formula covers most pie chart questions.
Topic 5: Averages
Frequency: High — appears in most CLAT papers, often embedded in percentage or ratio passages.
Averages test your ability to quickly summarise data and are one of the most straightforward topics in CLAT QT when approached correctly.
What CLAT tests: Calculating the mean of a set of values, finding a missing value when the average is given, calculating weighted averages, and comparing averages across two groups.
Key formulas to know:
- Average = Sum of all values / Number of values
- Sum = Average × Number of values (use this to find the missing value)
- Weighted average = (Sum of each value × its weight) / Total weight
How it appears in the paper: A passage presenting earnings, marks, or production data for a group, with questions asking for the group average, the average after adding/removing one member, or comparison between two groups’ averages.
Preparation tip: The most common CLAT average question type involves finding the sum from the average (Sum = Average × Count) and then using that sum to derive a new value. Practice this calculation direction — most students instinctively think average → individual values, but CLAT more often requires individual values → average or sum.
Topic 6: Profit, Loss, and Discount
Frequency: Moderate to high — appears consistently, especially in passages involving commercial or business scenarios.
Profit, Loss, and Discount questions are among the most straightforward in CLAT QT once the formulas are memorised — making them reliable scoring opportunities.
What CLAT tests: Calculating profit or loss as a percentage of cost price, finding selling price from cost price and profit percentage, applying successive discounts, and computing marked price vs selling price.
Key formulas to know:
- Profit% = (Profit / CP) × 100
- SP = CP × (1 + Profit%/100)
- Discount% = (Discount / Marked Price) × 100
- Net discount for two successive discounts of a% and b% = a + b − (ab/100)
How it appears in the paper: A short business scenario passage — a shopkeeper buying goods at a cost price and selling at a marked price with a discount, followed by questions asking for profit percentage, selling price, or effective discount.
Preparation tip: Always identify whether the percentage is calculated on Cost Price (for profit/loss) or Marked Price (for discount) — the distinction is where most errors occur. When in doubt, write CP and SP clearly before calculating.
Topic 7: Simple Interest and Compound Interest
Frequency: Moderate — appears intermittently, more common in years when the QT passage involves banking or financial data.
What CLAT tests: Calculating SI and CI for given principal, rate, and time; finding the difference between CI and SI; comparing returns across two financial instruments.
Key formulas to know:
- Simple Interest = (P × R × T) / 100
- Compound Interest = P × [(1 + R/100)^T − 1]
- For 2 years, CI − SI = P × (R/100)²
- For CLAT, T is typically 1–3 years — keep calculations manageable
How it appears in the paper: A passage involving a person investing money in a bank or scheme, with questions asking for the interest earned or the final amount after a specified period.
Preparation tip: For most CLAT CI questions, the time period is 2 years — making the calculation formula manageable without a calculator. Know the 2-year CI formula by heart and practise applying it to round numbers quickly.
Topic 8: Time, Work, and Pipes
Frequency: Moderate — appears in some years, particularly when the QT passage is set in an industrial or project context.
What CLAT tests: Calculating combined work rate when multiple workers or machines work together, finding the time taken to complete a task given individual rates, and solving pipe-filling or pipe-emptying problems.
Key formulas to know:
- If A completes a task in X days, A’s rate = 1/X per day
- Combined rate of A and B = 1/X + 1/Y; Time together = XY/(X+Y)
- Pipe A fills in X hours, Pipe B empties in Y hours; Net rate = 1/X − 1/Y
How it appears in the paper: A passage describing workers completing a project or pipes filling a tank, with questions asking for time taken or work completed in a given period.
Preparation tip: Always convert the problem to rates (fraction of work per day or hour) before calculating. Students who try to intuit these problems without converting to rates almost always make errors. The rate-based approach is slower to set up but produces the right answer consistently.
Topic 9: Number System and Basic Arithmetic
Frequency: Moderate — provides the conceptual foundation for several other topics and appears directly in some papers.
What CLAT tests: Factors and multiples, divisibility rules, LCM and HCF, prime numbers, and basic properties of integers. These appear both as standalone questions and as embedded calculations within larger DI sets.
Key concepts to know:
- Divisibility rules for 2, 3, 4, 5, 6, 8, 9, 11
- LCM × HCF = Product of two numbers
- A number is prime if it has no factors other than 1 and itself
- Perfect squares up to 400 (speeds up calculation across multiple topics)
How it appears in the paper: A passage presenting numerical data about groups, distributions, or arrangements, with questions that require identifying factors, finding LCM/HCF, or applying divisibility to filter options quickly.
Preparation tip: This topic rewards students who know their multiplication tables up to 20 and their squares up to 30 by heart. In a no-calculator exam, mental arithmetic fluency saves 30–60 seconds per question — time that matters enormously in a 120-minute paper.
Topic 10: Mensuration — Area, Perimeter, and Volume
Frequency: Lower but non-negligible — appears when QT passages describe land, floor space, construction, or geometric arrangements.
What CLAT tests: Area and perimeter of rectangles, squares, triangles, and circles. Volume of cubes, cuboids, and cylinders. Comparing two shapes’ areas or volumes given a constraint.
Key formulas to know:
- Rectangle: Area = l × b; Perimeter = 2(l + b)
- Circle: Area = πr²; Circumference = 2πr (use π = 22/7 or 3.14)
- Triangle: Area = ½ × base × height
- Cube: Volume = a³; Surface area = 6a²
- Cuboid: Volume = l × b × h
How it appears in the paper: A passage describing a field, room, or container with given dimensions, followed by questions asking for area, perimeter, or volume — sometimes with a comparison (e.g., “if the length increases by 20%, by what percentage does the area change?”).
Preparation tip: Mensuration questions in CLAT are typically single-step calculations — identify the shape, apply the formula, and calculate. The passages are short and the numbers are usually clean (designed to be solved without a calculator). Do not overthink these.

Section Strategy for CLAT Quantitative Techniques
Knowing the topics is necessary. Having a strategy for the 10–12 minutes you have to spend on this section is what converts that knowledge into marks.
Attempt QT Last — Always
QT is the only section in CLAT where a single difficult DI set can consume 4–5 minutes without producing a correct answer. Attempting it last ensures that if you run over time on a difficult passage, you have already secured marks in higher-volume sections. This is the most consistent time management advice from CLAT toppers and coaching faculty alike.
Identify and Solve the Easy Questions First
Within the QT section, not all questions are equally time-consuming. A standalone percentage or average question with clean numbers can be solved in 40–50 seconds. A complex multi-variable DI table with messy numbers can take 3–4 minutes. Scan the QT passages before attempting and solve the straightforward questions first — then return to the time-intensive ones if time permits.
Apply the 90-Second Rule
If a QT question has not yielded an answer within 90 seconds, mark it and move on. There is no partial credit in CLAT, and a 90-second abandoned question is less costly than a 4-minute wrong answer with negative marking.
Never Guess Blindly — The Negative Marking Is Real
At −0.25 per wrong answer, blind guessing in QT is a losing strategy. If you have eliminated two of four options, a calculated guess is worth attempting. If you cannot eliminate any option, leave the question blank. Unlike some competitive exams, CLAT QT’s negative marking makes strategic skipping more valuable than speculative attempts.
The Formula You Need to Remember About CLAT QT
The Quantitative Techniques section carries only 10 per cent weightage in the CLAT exam, yet it can prove to be a deciding factor for those aiming for law admissions at the prestigious NLUs. A candidate cannot risk losing marks in CLAT by not preparing the Quantitative Techniques section.
Ten questions at one mark each — fully solved — can be the difference between rank 150 and rank 350. In a paper where margins of two to three marks separate top NLUs, dismissing QT as a minor section is among the costliest preparation mistakes an aspirant can make.
The ten CLAT Quantitative Techniques topics in this guide cover everything that has been tested in the exam from 2020 to 2026. None of them require knowledge beyond Class 10. All of them are learnable in four to six weeks of focused practice. There is no excuse for leaving marks on the table in this section.
Final Word
The CLAT Quantitative Techniques topics most aspirants fear are, in reality, among the most learnable parts of the entire paper. Class 10-level mathematics, passage-based format, clean numbers, and predictable question types — this is not a section designed to test advanced mathematical ability. It is designed to test whether you can read data accurately, apply basic formulas under time pressure, and make smart decisions about which questions to attempt.
Master the ten topics in this guide. Build your formula fluency. Practise from previous year CLAT papers under timed conditions. And stop treating QT as the section you will figure out later — because in CLAT 2027, later arrives faster than you expect.
