Important 3 Marks Question For CBSE Class 10 Maths

3 marks class 10 maths questions are specific short-answer problems that require logical steps and clear calculations. These questions bridge the gap between simple one-markers and complex long-form queries. Students must show their working clearly to earn full credit, as examiners look for specific formulas and correct intermediate steps during the evaluation process.

How to Solve 3 Marks Class 10 Maths Questions

To do well in your board exam, you need to learn how to handle the middle part of the paper. These problems usually ask you to show how a rule works or to solve a math problem with a few steps. Think of these as a way to show you really know the "why" behind the math.

• How much they count: This part of the exam usually makes up one-third of your total marks.

• Watch the clock: Try to finish each of these problems in about five to seven minutes.

• Marks for steps: Even if your final answer is wrong, you can still get some marks for writing the right formula.

• Stay neat: Use a sharp pencil for drawings and keep your rough work in a neat line on the side.

Easy 3 Marks Questions Class 10 Maths

The best way to get ready is to look for questions that show up year after year. Many times, you will have to find a missing number like "k" or prove that a shape follows a certain rule. Always write a final sentence at the end of your answer because that can get you extra points.

Circles and Shapes

You will often have to prove things about lines that just touch a circle.

• Show that two lines drawn from the same point outside a circle are the same length.

• Find the area of a colored part inside a circle shape.

Mean and Chances

These are easy to score in if you count carefully and don't rush your plus and minus work.

• Find a missing number in a table when you already know the average (mean).

• Find the chance (probability) of winning a game with dice or coins.

Learn 3 Marks Questions for Class 10 Maths Chapter 1

In the first chapter about Real Numbers, the questions are very similar every year. Most 3 marks class 10 maths questions here are about how prime numbers work or why some numbers are special. If you learn these two types of problems, you will get easy marks.

The "Special" Numbers

A very common question is to prove that a number like $\sqrt{5}$ is not a normal fraction.

1. Pretend the number is a normal fraction ($a/b$).

2. Show that this idea leads to a mistake or a "clash."

3. Say that because of this clash, the number cannot be a normal fraction.

4. Write down that your proof is finished.

Word Problems with HCF and LCM

You might see stories about bells that ring at different times or kids running in a circle.

• Find the HCF if the question asks for the "biggest" or "largest" thing.

• Find the LCM if it asks "when will they meet again" or for the "smallest" time.

Help with 3 Marks Questions for Class 10 Maths Chapter 2

Polynomials are all about finding numbers that make a math sentence equal to zero. These 3 marks class 10 maths questions check if you know how these "zeroes" relate to the other numbers in the problem. We suggest checking your work by adding and multiplying your answers at the end.

The Zeroes Rule

If you have two special numbers (called zeroes), you must show:

• Adding them gives you $-b/a$.

• Multiplying them gives you $c/a$.

Dividing Math Sentences

You might have to divide a big math sentence by a smaller one using long division.

1. Write the powers of $x$ from biggest to smallest.

2. Be very careful when you subtract negative numbers.

3. Check if (Divisor × Answer) + Remainder gives you the starting number.

Simple 3 Marks Questions for Class 10 Maths Real Numbers

When you work on Real Numbers, pay attention to how numbers are built from smaller prime numbers. This helps you explain why some numbers can't end in a 0 or a 5. Teachers love to ask this because it shows you understand how numbers work.

Ending Decimals

Can you tell if a fraction stops or goes on forever without actually dividing?

• Look at the bottom number of the fraction.

• If the bottom only has 2s and 5s as its "building blocks," it will stop (terminate).

• If it has any other prime numbers, it will keep going and repeating.

Points on a Graph

Sometimes you have to find a spot on a flat map (graph) that is the same distance from two other spots.

• Write the distance rule for both sides.

• Get rid of the square root signs.

• Solve for the missing number.

FAQs on 3 Marks Class 10 Maths Questions

Do I need to write down what the question tells me?

Yes. Writing "Given" and "To Prove" helps you think clearly and shows the teacher you understand the goal.

What if I forget a math rule?

Don't panic. Try to solve other parts of the question or move to the next one. You might remember it later when you are more relaxed.

How do I answer "Prove that" questions?

Always start with one side of the equal sign. Change it step by step until it looks exactly like the other side.

Is the side-work important?

Yes. Always keep a neat space on the right side of your paper for your rough multiplying and adding. It keeps your main answer looking clean.

Which chapter is the best one to start with?

Most students find the chapters on Mean (Statistics) and Real Numbers the best because the steps stay the same every time.Would you like me to make a list of practice problems for these 3-mark questions?

When you sit down to study, make sure you spend extra time on the harder chapters. We suggest starting with 3 marks questions for class 10 maths polynomials because they help you understand the core rules of algebra that you will need for the rest of the exam.
