When you sit down to prepare for the WB ANM GNM exam, one section you can’t take lightly is Mathematics. Don’t worry, it’s not advanced maths like calculus or trigonometry. The exam mainly tests your class 10-level concepts, so you are already familiar with most of them. The math section has around 10 questions (1 mark each). In this article, we will help you with the important chapters for the WB ANM GNM 2025 exam and explain all the details so you can revise perfectly.
List of WB ANM GNM Mathematics Important Chapters 2025
The maths questions in WB ANM GNM are based on the West Bengal Class 10 syllabus. That means topics you have already studied, but here the exam tests how well you can apply them in problem-solving. Here are the important mathematics chapters that you should prepare for.

WB ANM and GNM 2025 Important Examination Rules
1. Number System and Variables
This is the base of everything. Questions may look simple, but they test how quickly you can work with numbers and represent them using variables. You can practice writing everyday problems in variable form. For example, “If the cost of 1 pen is x, the cost of 5 pens is 5x.”
What to Study | Why It’s Important |
Types of numbers - natural, whole, integers, rational | Builds your foundation for other topics |
Variables in expressions | Helps in solving small algebra-based questions |
Prime factorization basics | Links to LCM, HCF, and Fundamental Theorem |
2. Like and Unlike Fractions
Fractions always carry good weight in this exam. You’ll need to add, subtract, multiply, and divide both like and unlike fractions. Keep a sheet of common denominators handy when practising. It trains your brain to simplify faster.
What to Study | Why It’s Important |
Simplifying fractions | Appears in 3-4 questions |
Converting unlike fractions to like | Essential for addition/subtraction |
Fraction word problems | Common in the exam |
3. Multiplication and Division
Sounds basic, right? But examiners love testing simple multiplication and division, especially with large numbers, fractions, or decimals.
What to Study | Why It’s Important |
Multiplication/ division of whole numbers | Builds accuracy |
Operations with fractions and decimals | Frequently tested |
Word problems (division as sharing) | Real-life application based |
4. Law of Exponents
If you memorize the laws, this chapter becomes one of the easiest scoring areas. You can write these rules on a flashcard and revise them every morning.
Rule | Example |
a^m × a^n = a^(m+n) | 2³ × 2² = 2⁵ |
(a^m)^n = a^(m×n) | (3²)³ = 3⁶ |
a^0 = 1 | 7^0 = 1 |
a^-n = 1/a^n | 2^-3 = 1/8 |
5. Integers in a Number Line
Integers seem simple, but examiners love to test sign rules and number line understanding.
What to Study | Why It’s Important |
Placing integers on a number line | Basic but commonly asked |
Addition and subtraction using the number line | 2-3 questions appear every year |
Rules of signs | Prevents silly mistakes |
6. Word Problems on Decimals
Decimals generally appear in situations like costs, distances, or measurements.
What to Study | Why It’s Important |
Addition, subtraction, and multiplication of decimals | 3-4 frequent questions |
Conversion of decimals to fractions | Helpful in applied problems |
Word problems involving money or length | Direct exam relevance |
7. Fundamental Theorem
This may not carry heavy weightage, but when it comes, it’s usually straightforward.
What to Study | Why It’s Important |
Prime factorization of numbers | Often tested in LCM/ HCF questions |
Using factorization in word problems | Simplifies big calculations |
Quick tricks for divisibility | Time-saving in the exam |
8. Ratio and Proportion
This is one of the most practical and repeated chapters. You will face at least 2-3 questions from this chapter.
What to Study | Why It’s Important |
Basic ratio simplification | Always tested |
Direct and inverse proportion | 2-3 questions almost every year |
Word problems (age, mixture, work sharing) | High application value |
9. Percentages
Percentages are a must-prepare chapter. They link to profit, loss, discounts, and everyday calculations.
What to Study | Why It’s Important |
Basic % calculation | Repeated questions |
Profit, loss, discount | Very common |
Percentage increase/decrease | Seen in word problems |
10. Fraction to Decimal Conversion
This is usually a quick question type, but it also helps in other chapters, like percentages.
What to Study | Why It’s Important |
Converting fractions into decimals | Easy scoring |
Repeating decimals | Occasionally tested |
Decimal to fraction conversion | Supports other problems |
11. Geometric Sequence
Not a heavyweight chapter, but you might see one question from here.
What to Study | Why It’s Important |
nth term formula (a × r^(n-1)) | Direct questions |
Finding a common ratio | Simple but needs clarity |
Small sequence sums | Occasionally asked |
