Mathematics Questions for RRB NTPC: Mathematics is the backbone of the RRB NTPC paper – predictable, high-yield, and extremely coachable. This article collects the most important types of Mathematics Questions for RRB NTPC, explains why they matter, gives representative practice questions with worked solutions, and offers a practical strategy and cheat-sheet you can use during revision.
Why Focus on these Mathematics Questions?
Mathematics is an important subject in the RRB NTPC Syllabus. Some of the main reasons why candidates must focus on these questions are as follows:
- They appear repeatedly across years and zones.
- Many are short, objective, and mark-dense – quick wins if practiced.
- With timed practice you can score high in the Maths section even if your fundamentals are average.
Important RRB Group D Mathematics Topics
Every exam applicant must cover the important mathematics topics from the syllabus. Given below are some topics:
- Number System & Divisibility — LCM, HCF, remainders, divisibility rules.
- Ratio, Proportion & Percentage — mixtures, profit & loss, successive percentages.
- Time, Speed & Distance — relative speed, trains, boats and streams.
- Work & Time — efficiency problems, pipes and cisterns.
- Algebra (Basic) — linear equations, simple quadratics, surds.
- Simple & Compound Interest — yearly/compound, nominal vs effective.
- Mensuration — area, perimeter, surface area & volume of common shapes.
- Geometry & Trigonometry (basic) — angles, triangles, sin/cos basics for simple problems.
- Average, Ratio & Proportion, and Problems on Ages — direct formulaic application.
- Partnership, Probability & Permutation/Combination (basic) — mostly short questions.
Topic Wise Distribution of RRB NTPC Mathematics Topics
The table below shows the topic-wise distribution and importance of RRB NTPC Mathematics topics:
| Topic | % of Maths Questions (approx.) | Why important |
| Number System & Arithmetic | 25% | Short, repeated question types |
| Algebra | 15% | One or two straightforward equations |
| Geometry/Mensuration | 12% | Formula based; easy if memorized |
| Time/Work & Time/Speed | 18% | Standard patterns; train/boat staples |
| Ratio/Percentage/Average | 20% | Frequent across tests |
| Misc (Probability, Partnership) | 10% | Occasional but doable |

Common Mistakes
There are certain mistakes that candidates repeatedly make. Some of these are given below:
- Skipping unit conversions (km/h to m/s).
- Misreading “successive” vs “simultaneous” percentages.
- Neglecting to rationalise surds or simplify fractions wastes time.
- Using calculator habits in mock tests; practice without a calculator where possible (paper-based exam mindset).
Time Management Strategy for RRB NTPC Exam
Having a proper time management strategy is mandatory to score well in the exam. Essential tips are given below:
- First 10–12 minutes: solve all very easy arithmetic and number system questions (easy marks).
- Next 20–25 minutes: take on time/speed, work/time, and straightforward algebra.
- Last 15–20 minutes: tackle mensuration, geometry and trickier algebra.
- If a question looks messy or long, mark it and move on — come back only if time permits.
Revision Plan for Exam Aspirants
Applicants must have a proper revision plan for the important topics. We have shared below a sample revision plan:
- Days 1–7: Master formulas and do topic-wise short quizzes (20 Qs/day).
- Days 8–16: Take timed mock tests; review mistakes thoroughly.
- Days 17–24: Focus on weak topics; do mixed topic sets under timed conditions.
- Days 25–30: Light revision: formula sheet, 2 full mocks, and relax the day before the test.
Key Points of Mathematics Questions for RRB NTPC
The key points of the article are summarized below for the applicants:
- Prioritize Number System, Percentage, Time/Work, and Time/Speed — they give most easy marks.
- Memorize a small formula sheet (LCM/HCF, CI, area/volume, relative speed).
- Practice short, timed sets to build speed and accuracy. Aim to solve the first 10–12 Maths questions within 10–12 minutes.
- Avoid traps: convert units, read “successive” correctly, and never assume integer answers.
- Mock review is more important than extra practice questions — analyze mistakes, not just attempt tests.
Mathematics Questions for RRB NTPC reward disciplined practice and formula mastery. The exam favors accuracy and speed – both learned through deliberate, repeated practice of the high-priority topics listed above. Use the cheat-sheet and time management plan, practice the representative problems until your method is automatic, and you’ll convert mathematics into a strong scoring section on the RRB NTPC.
FAQs
High-priority topics include Number System, Simplification, Time & Work, Time, Speed & Distance, Ratio & Proportion, Percentage, Profit & Loss, Simple & Compound Interest, Mensuration, and basic Algebra & Geometry. Mastering these areas can help secure maximum marks in the Maths section.
Typically, Mathematics accounts for 25–30 questions in the RRB NTPC CBT-1 and CBT-2 exams, out of 100 questions in total, depending on the stage of the exam.
Yes. Practicing shortcut methods for topics like simplification, percentage, time-speed-distance, and interest calculations can save significant time and improve accuracy during the exam.
Absolutely. Key formulas include:
LCM × HCF = Product of two numbers
Simple Interest: SI = (P × R × T)/100
Compound Interest: A = P(1 + R/100)^T
Time = Distance / Speed, Relative Speed formulas
Area and Volume formulas for rectangle, square, triangle, circle, cylinder, cuboid
Solve topic-wise practice sets first.
Attempt timed mock tests to improve speed and accuracy.
Review mistakes and revise trick methods and formulas regularly.
Focus on high-yield topics first and gradually cover all areas.
