Why Mathematics for Group D Railway Exam is Critical

In the cut-throat scenario of the 2026 exams, math for RRB group D is a scoring area. This area always marks 25 out of the 100 marks. Unlike General Awareness, math provides the surety of "fixed marks" if your logic and calculation are right. By Means of studying through specialized study material such as Smartkeeda, Testbook, and Physics Wallah, students can learn to:

Identifying Repeat Formats: Observe how topics like BODMAS or Divisibility Rules feature in almost all changeovers.
Refine Speed: Practice maths groups d questions in order to refine speed versus accuracy.
Learn Shortcuts: Learn tricks for calculating square roots, reciprocals, and percentage conversions that could cut down valuable seconds in the 90-minute long exam.

Detailed RRB Group D Math Questions with Solutions

The mathematics involved in Group D railway exam is normally at a level corresponding to CBSE Class 10 maths. On the lines of standard formats available for CBSE Class 10, some model questions can be provided as per standard patterns, along with their stepwise solution to give you an idea about the basic concept.

Sample Questions & Explanations

1. Number System (Divisibility)

Question: If the number 5432*2 is divisible by 9, then what is the digit in place of *?
Solution: A number is divisible by 9 if the sum of its digits is divisible by 9.
Sum = 5 + 4 + 3 + 2 + * + 2 = 16 + *.
The next multiple of 9 after 16 is 18.
Therefore, 16 + * = 18, which means ** * = 2**.

2. Time, Speed, and Distance (Trains)

Question: A train 125 m long passes a man running at 5 km/hr in the same direction in 10 seconds. Find the speed of the train.
Solution:

Relative Speed = Distance / Time = 125 / 10 = 12.5 m/s.
Convert m/s to km/hr: 12.5 x (18 / 5) = 45 km/hr.
Since they are in the same direction, Relative Speed = Train Speed - Man Speed.
45 = Train Speed - 5.
Train Speed = 50 km/hr.

3. Simple Interest

Question: Find the Simple Interest on a principal of 2000 at 5% rate for 3 years.
Solution: Use the formula SI = (P x R x T) / 100.

SI = (2000 x 5 x 3) / 100 = 300.
Answer: 300.

High-Weightage Topics to Focus On

Based on an analysis of the RRB group d math question previous year pdf files, the following topics carry the most weight:

Arithmetic: Number System, BODMAS, Percentages, and Averages.
Algebra: Linear and Quadratic Equations, Identities.
Mensuration: Area and Volume of 2D/3D shapes (Cylinders, Spheres, Cones).
Advanced Math: Trigonometry (Identities, Heights, and Distances), Geometry (Triangles, Tangents).

Strategic Preparation for 85+ Marks in 2026

To hit the high scores needed for the 32,438 vacancies in the 2025-26 cycle, candidates must transition from basic learning to exam-oriented execution. The competition is intense, and the 1/3 negative marking means that accuracy is just as important as speed.

The "Mistake Register" Technique

A highly recommended strategy by experts is maintaining a dedicated mock test notebook. Every time you solve an RRB group d math question and get it wrong or find it too time-consuming, write it down.

Note the Solution: Don't just mark it wrong; write out the correct, shortest method.
Daily Review: Spend 15 minutes every morning looking at this register. This prevents the "repetitive error" cycle and builds confidence in weak areas like Mensuration or Algebra.

Speed Mathematics and Vedic Tricks

In the 90-minute window for 100 questions, you cannot afford to do long-form multiplication.

Mental Arithmetic: Practice fraction-to-percentage conversions (e.g., 1/7 = 14.28%).
Simplification Tricks: Use the BODMAS rule strictly and learn Vedic methods for finding squares and cubes up to 30.
Unit Conversion: Instantly convert km/hr to m/s by multiplying by 5/18.

The Strategic Advantage of Mock Test Analysis

Just solving problems is not adequate for the RRB group d math question section; you must become a master in post-test analysis. Revising your mistakes in a maths railway group d question set helps you analyze between the error being due to calculation or conceptual. This disciplined approach entails that you would not be committing the same mistakes in the actual 2026 exam, consequentially bringing considerable improvement in overall accuracy and confidence level.
