SSC CHSL Quantitative Aptitude: Topics, Weightage & a Day-Wise Practice Plan
Quant decides many CHSL results. Tier 1 has only 25 questions on it, yet they often separate a safe score from a miss. Most students feel stuck for the same reasons: fear of maths, little time, and no clear place to start. This post gives you the topics, their weightage, a 30-day plan, and the mistakes to avoid.
Try this quick self-check first:
How comfortable are you with percentages? Beginner, Okay, or Strong?
How well do you know squares up to 30? Slow, Medium, or Fast?
How many hours can you give daily? One, two, three, or more?
SSC CHSL Quantitative Aptitude at a Glance
Quant is one of four sections in Tier 1. It carries 25% of the paper and tests school-level maths, mostly up to Class 10. Tier 2 has a longer maths section with harder questions.
Detail | Tier 1 | Tier 2 |
Maths questions | 25 | 30 |
Marks for maths | 50 | 90 |
Marks per question | 2 | 3 |
Negative marking | 0.50 per wrong answer | 1 per wrong answer |
Time | 60 minutes for all four sections | Check the notification |
Note: Always confirm the latest pattern on the official SSC notification. SSC has changed the exam format before.
Tier 1 has no separate timer for each section. You decide how long to spend on quant. Because the overall cutoff is the sum of all four sections, strong quant marks can cover weaker areas elsewhere.
SSC CHSL Maths Syllabus: Complete Topic List
The syllabus has seven groups of topics. Learn them in the order below, since the later topics use skills from the earlier ones.
Arithmetic
Arithmetic is the largest part of the paper. It covers Percentage, Profit and Loss, Ratio and Proportion, Average, Time and Work, Time-Speed-Distance, Simple and Compound Interest, Mixture and Alligation, and Partnership.
Example type: A shopkeeper buys a shirt for ₹400 and sells it at a 25% profit. Find the selling price.
Number System and Simplification
This group tests how fast and correctly you calculate. It includes BODMAS (the order of operations), divisibility rules, remainders, and approximation.
Example type: Find the remainder when 7⁴ is divided by 5.
Algebra
Expect linear equations, standard identities, and simple algebraic expressions. The questions are usually short.
Example type: If x + 1/x = 3, find x² + 1/x².
Geometry
Geometry covers lines and angles, triangles, circles, and similarity. Knowing the theorems matters more than long calculations.
Example type: Two angles of a triangle are 50° and 60°. Find the third.
Mensuration
Mensuration means finding area, perimeter, surface area, and volume of 2D and 3D shapes such as circles, cones, cylinders, and spheres.
Example type: Find the volume of a cylinder with radius 7 cm and height 10 cm.
Trigonometry
This covers trigonometric ratios, standard identities, and heights and distances. Learn the table of values for 0°, 30°, 45°, 60°, and 90°.
Example type: If sin θ = 3/5, find cos θ.
Data Interpretation and Statistics
You read tables, bar charts, and pie charts, and find the mean, median, and mode. The calculation is simple, but you must read the chart carefully.
Example type: A bar chart shows sales for five months. Find the average monthly sale.
SSC CHSL Maths Topic-Wise Weightage (What to Study First)
Arithmetic gives the most questions, so study it first. The numbers below are approximate trends from previous years' papers. SSC does not publish a fixed split, and it changes each year.
Topic | Approx. questions | Difficulty | Priority |
Arithmetic | 9 to 11 | Easy to Medium | High |
Number System and Simplification | 2 to 3 | Easy | High |
Algebra | 2 to 3 | Medium | Medium |
Geometry | 3 to 4 | Medium to Hard | High |
Mensuration | 2 to 3 | Medium | Medium |
Trigonometry | 2 to 3 | Medium | Medium |
Data Interpretation and Statistics | 1 to 2 | Easy | Low |
The 80/20 rule of CHSL quant: Arithmetic plus Algebra plus Geometry carries most of the paper. Master these three before spending time on rare topics.
Pick your weakest topic. Which one is it: Arithmetic, Geometry, Algebra, Mensuration, Trigonometry, or DI? Note it down. Give that topic an extra 30 minutes each week in the plan below.
How to Prepare Maths for SSC CHSL from Scratch
Start with calculation basics, then learn one topic at a time, and then practice with a timer. This order works because speed comes from strong basics, not from tricks.
Step 1: Fix the basics. Learn tables up to 30, squares up to 30, cubes up to 15, and common fraction-to-percentage values (1/8 = 12.5%, 1/6 = 16.67%).
Step 2: Learn concepts topic by topic. Finish one topic before starting the next. Jumping between topics leaves gaps.
Step 3: Practice with timers. Set 20 minutes for 15 questions. The clock builds exam habits early.
Step 4: Keep a mistake notebook. Write each wrong question, the reason you got it wrong, and the correct method. Re-read it every Sunday.
Step 5: Take sectional tests, then full mocks. Attempt topic tests first. Move to full mocks once you finish the SSC CHSL syllabus.
Which learner are you?
Beginners: Follow the 30-day plan from Day 1. Spend the first three days only on basics.
Repeaters: Skip topics you scored well on. Start with your mistake list from the last attempt and take a mock in Week 1.
Working candidates: Study 60 to 90 minutes on weekdays and 3 hours on weekends. Practice on your phone during travel.
SSC CHSL Quant 30-Day Practice Plan
This plan covers the full syllabus in four weeks. It assumes about 1.5 to 2 hours a day.
Week | Focus topics | Goal |
Week 1 | Basics, number system, percentage, ratio, average | Solve basic questions in under 1 minute |
Week 2 | Profit and loss, time and work, time-speed-distance, interest | Know every formula without looking |
Week 3 | Algebra, geometry, mensuration, trigonometry | Finish all theorems and identities |
Week 4 | Data interpretation, mixed practice, full mocks | Take 3 to 4 full mocks and review each |
Daily routine template
20 minutes: theory and formulas
40 minutes: practice questions
20 minutes: revision of earlier topics
15 minutes: mistake notebook
Tick off your day. Mark each finished day on a calendar. If you read this online, comment "Day 1 done" and keep a streak going.
Need more time? 60-day and 90-day tweaks
Double each week's length for 60 days, so each week becomes two. This gives time for extra practice sets. For 90 days, add one full week of Class 8 to 10 maths revision at the start, and take one mock every week from Day 45.
Last 15 days before the exam
Do not start new topics. Take one full mock every alternate day and spend the other days reviewing mistakes. Revise formulas and shortcuts daily for 20 minutes.
How to Improve Speed and Accuracy in SSC CHSL Maths
You gain speed by choosing the right questions and using simple calculation methods. Accuracy matters just as much, because each wrong answer costs 0.50 marks.
Calculation tricks:
Learn squares and cubes by heart.
Use approximation in simplification questions. Round 49.8 to 50 when options are far apart.
Use Vedic shortcuts, such as multiplying by 11, only after you understand the basic method.
Question selection:
Attempt easy topics such as percentage, average, and simplification first.
Skip long questions on the first round and return if time remains.
Target numbers:
Attempts: 20 to 22 questions
Accuracy: 85% or higher
Time: about 15 to 18 minutes for the section, which is roughly 40 seconds per question
How many questions are safe to attempt? Cutoffs change every year and differ by post and category. Check the cutoff of previous years on the official result notices, then aim 10 to 15 marks above it. Do not guess blindly: three wrong answers cancel out one correct answer plus half a mark.

Common Mistakes in SSC CHSL Quant (and Fixes)
Most lost marks come from habits, not from lack of ability. Check yourself against these five.
Studying too many topics at once. You forget old ones. Fix: Finish one topic before starting another.
Skipping mocks. You never learn your real speed. Fix: Take at least one mock a week from Week 3.
Ignoring weak areas. One weak topic can cost 3 to 4 questions. Fix: Give it extra time every week.
Memorizing without understanding. A changed question breaks the formula. Fix: Learn why a formula works, then memorize it.
No timing practice. You know the answer but run out of time. Fix: Solve every practice set with a timer.
Sample Questions and Quick Solutions
These five questions show the common patterns. Try each one before you read the answers.
A price rises by 20% and then falls by 20%. What is the net change?
A 300 m long train crosses a pole in 15 seconds. What is its speed in km/h?
The angles of a triangle are in the ratio 2:3:4. Find the largest angle.
A can finish a job in 10 days and B in 15 days. How many days will they take together?
If x + 1/x = 3, find x² + 1/x².
Try before you scroll. Answers are below.
1. Net change = 4% decrease. Trick: for successive changes of x% and y%, net change = x + y + (xy/100). Here, 20 − 20 − 4 = −4%.
2. 72 km/h. Speed = 300 ÷ 15 = 20 m/s. Multiply by 18/5 to convert to km/h: 20 × 3.6 = 72.
3. 80°. The ratio adds up to 9 parts. One part = 180 ÷ 9 = 20°. The largest angle = 4 × 20 = 80°.
4. 6 days. Trick: for two people, time together = (A × B) ÷ (A + B) = 150 ÷ 25 = 6.
5. 7. Square both sides: x² + 2 + 1/x² = 9. So x² + 1/x² = 9 − 2 = 7.
