CBSE Class 10 Maths Solutions: Questions and Answers

  1. What is the value of x if 2x + 5 = 15?
    Answer: To solve for x, subtract 5 from both sides to get 2x = 10. Then, divide by 2 to get x = 5.

  2. If a triangle has angles of 30°, 60°, and 90°, what type of triangle is it?
    Answer: This is a right-angled triangle because one angle measures 90°.

  3. Find the area of a circle with a radius of 7 cm.
    Answer: The area of a circle is calculated using the formula πr². So, the area = π * 7² = 49π cm².

  4. What is the perimeter of a rectangle with length 12 cm and width 5 cm?
    Answer: The perimeter of a rectangle is calculated by adding twice the length and twice the width: 2(12 + 5) = 34 cm.

  5. What is the solution to the equation 3y – 4 = 14?
    Answer: Add 4 to both sides to get 3y = 18. Then divide by 3 to find y = 6.

  1. A person invests ₹5000 at an interest rate of 5% per annum. What is the amount after 2 years?
    Answer: Use the formula for simple interest: A = P(1 + rt). A = 5000(1 + 0.05 * 2) = ₹5500.

  2. What is the volume of a cube with side length 4 cm?
    Answer: The volume of a cube is side³, so the volume = 4³ = 64 cm³.

  3. Simplify the expression: 2x + 3x – 5.
    Answer: Combine like terms to get 5x – 5.

  4. A cylindrical container has a radius of 3 cm and a height of 10 cm. What is its volume?
    Answer: The volume of a cylinder is πr²h. So, the volume = π * 3² * 10 = 90π cm³.

  5. What is the median of the numbers 5, 8, 12, 15, 20?
    Answer: Arrange the numbers in order: 5, 8, 12, 15, 20. The median is the middle number, so the median = 12.

  6. If a right triangle has one leg of 8 cm and the other leg of 15 cm, what is the length of the hypotenuse?
    Answer: Use the Pythagorean theorem: a² + b² = c². So, 8² + 15² = c², which gives c² = 64 + 225 = 289, so c = 17 cm.

  7. Solve for x: 5x – 10 = 20.
    Answer: Add 10 to both sides to get 5x = 30. Then divide by 5 to get x = 6.

  8. A triangle has sides of 7 cm, 24 cm, and 25 cm. Is it a right-angled triangle?
    Answer: Check if 7² + 24² = 25². 49 + 576 = 625, which is true, so it is a right-angled triangle.

  9. If the area of a circle is 154 cm², what is its radius?

Having access to reliable CBSE Class 10 Maths solutions can make a world of difference when it comes to understanding complex concepts and practicing effectively.

Why CBSE Class 10 Maths Solutions Matter

Maths solutions play a vital role in helping students grasp the concepts in a structured way. With numerous chapters and formulas to remember, it’s easy to lose track of the basics. Well-organized solutions not only help students solve problems efficiently but also clarify any doubts they may have while studying. The key to success in CBSE Class 10 Maths is practice, and solutions provide a step-by-step approach to help students tackle every question with confidence.

CBSE Class 10 Maths solutions are designed to offer clear, concise, and easy-to-follow explanations. Each problem is broken down into smaller, manageable steps, which help students understand the process behind the solution. Instead of simply giving the final answer, the solutions guide students through each stage of the problem, reinforcing the importance of logical thinking and accuracy.

For instance, when working on algebraic expressions or quadratic equations, students are shown how to manipulate terms or apply the right formula. This ensures that they not only know the answer but also understand the reasoning behind it.

The CBSE Class 10 Maths syllabus is vast, covering a range of topics from Number Systems to Coordinate Geometry. Each topic comes with its own set of challenges, but with proper guidance, even the toughest chapters can be mastered. Solutions provided for each chapter give students the opportunity to practice problems of varying difficulty levels. These solutions ensure that no topic is left unexplored, making students well-prepared for the exams.

Using CBSE Class 10 Maths solutions is an excellent way to boost exam preparation. By solving sample problems and referring to solutions, students get an idea of the types of questions that are likely to appear in the exam. Regular practice, combined with referring to accurate and well-explained solutions, enhances problem-solving speed, ensuring that students can manage their time efficiently during the exam.

Additionally, by revisiting difficult questions and comparing solutions, students can identify recurring mistakes and rectify them before the actual exam. This approach promotes thorough revision and helps reduce the chances of errors.

  1. Understand the Concept First: Before diving into the solutions, ensure that you have a clear understanding of the underlying concepts. Solutions work best when you already know the fundamentals.

  2. Solve Problems Independently: Try solving problems on your own first. Use the solutions only when you're stuck, and analyze each step carefully.

  3. Practice Regularly: Consistency is key in mastering Maths. Solve as many problems as you can, covering a variety of question types from the solutions.

  4. Focus on Weak Areas: Pay extra attention to the topics or types of problems that challenge you the most. Use the solutions to practice and improve these areas.
