Master Concise Mathematics Class 9 Solutions with Step-by-Step Answers
Algebra – Understanding Equations and Expressions
What is the value of x in the equation 5x - 7 = 18?
To solve for x, add 7 to both sides: 5x = 25. Now, divide by 5: x = 5.
Factorize the expression x² - 9x + 14.
Break it into factors: (x - 7)(x - 2).
Simplify (3x + 4) + (5x - 2).
Combine like terms: 8x + 2.
Solve for x: 2(x + 3) = 4x - 6.
Expand: 2x + 6 = 4x - 6. Rearrange: 2x = 12, so x = 6.
Find the product of (x + 5) and (x - 2).
Using expansion: x² - 2x + 5x - 10 = x² + 3x - 10.
Geometry – Exploring Shapes and Angles
If a triangle has angles 40° and 60°, find the third angle.
The sum of angles in a triangle is 180°. Third angle = 180° - (40° + 60°) = 80°.
A rectangle has a length of 10 cm and a width of 6 cm. Find its area.
Area = length × width = 10 × 6 = 60 cm².
Find the perimeter of a square with a side of 9 cm.
Perimeter = 4 × side = 4 × 9 = 36 cm.
The radius of a circle is 7 cm. Find its circumference using π = 3.14.
Circumference = 2 × π × r = 2 × 3.14 × 7 = 43.96 cm.
If two angles of a parallelogram are 70° and 110°, find the other two angles.
A parallelogram has opposite angles equal. So, the other angles are also 70° and 110°.
Trigonometry – Understanding Ratios and Heights
Find the sine of a 30° angle.
sin 30° = 1/2.
If tan θ = 3/4, find sin θ.
Using sin²θ + cos²θ = 1 and tan θ = sin θ / cos θ, we get sin θ = 3/5.
A ladder leans against a wall making a 60° angle with the ground. If the ladder is 10m long, how high does it reach on the wall?
Using sin 60° ≈ 0.866, height = 10 × 0.866 = 8.66 m.
Find the value of cos 0°.cos 0° = 1.
If a right-angled triangle has an opposite side of 5 cm and hypotenuse of 13 cm, find sin θ.
sin θ = opposite/hypotenuse = 5/13.
Probability and Statistics – Analyzing Data
What is the probability of rolling a 3 on a fair six-sided die?
There are six possible outcomes, and only one is 3. Probability = 1/6.
A bag contains 4 red, 5 blue, and 3 green balls. What is the probability of picking a red ball?
Total balls = 4 + 5 + 3 = 12. Probability = 4/12 = 1/3.
Find the mean of the numbers 2, 4, 6, 8, 10.
Mean = (2+4+6+8+10)/5 = 30/5 = 6.
Find the median of 3, 7, 2, 8, 10.
Arrange in order: 2, 3, 7, 8, 10. The median is the middle value = 7.
What is the mode of 2, 3, 3, 4, 5, 5, 5, 6?
Mode is the most frequent value = 5.
Mensuration – Calculating Areas and Volumes
Find the area of a triangle with base 12 cm and height 5 cm.
Area = ½ × base × height = ½ × 12 × 5 = 30 cm².
Find the volume of a cube with side length 4 cm.
Volume = side³ = 4³ = 64 cm³.
A cylinder has a radius of 3 cm and height of 7 cm. Find its volume (use π = 3.14).
Volume = πr²h = 3.14 × 3² × 7 = 197.82 cm³.
Find the surface area of a sphere with radius 5 cm (use π = 3.14).
Surface area = 4πr² = 4 × 3.14 × 5² = 314 cm².
A cone has a base radius of 6 cm and a height of 9 cm. Find its volume (use π = 3.14).
Volume = (1/3)πr²h = (1/3) × 3.14 × 6² × 9 = 339.12 cm³.
Coordinate Geometry – Working with Graphs
Find the distance between (2,3) and (6,7).
Using the distance formula: √[(6-2)² + (7-3)²] = √[16 + 16] = √32 = 5.66.

Midpoint = [(4+10)/2, (8+2)/2] = (7,5).
Find the equation of a line passing through (2,5) with slope 3.
Using y = mx + c: y - 5 = 3(x - 2), so y = 3x - 1.
If a line passes through (3,4) and (7,8), find its slope.
Slope = (8-4)/(7-3) = 4/4 = 1.
Find the x-intercept of the line 3x + 4y = 12.
Set y = 0: 3x = 12 → x = 4.

Mathematics in Class 9 sets the foundation for higher studies, and having the right solutions can make a significant difference in understanding complex topics. A well-structured guide with step-by-step solutions allows students to master concepts, solve problems efficiently, and build confidence in their mathematical skills.
One of the biggest challenges students face is grasping abstract mathematical concepts. A good solution book simplifies these concepts with clear explanations, logical derivations, and real-life applications. Step-by-step breakdowns of problems help students develop problem-solving strategies rather than just memorizing formulas.
Algebra and Equations play a major role in Class 9 Mathematics. Many students struggle with linear equations, polynomials, and factorization. A well-structured solutions book provides clear methods to solve equations efficiently, making it easier to understand the underlying logic behind algebraic operations. These books often include solved examples that illustrate different approaches to solving the same problem.
In Geometry, students encounter theorems, constructions, and angle properties. The right solutions book presents proofs in a structured manner, ensuring that students understand how to logically derive results. Visual representations, stepwise constructions, and problem-solving tricks help in mastering difficult concepts like circles, triangles, and coordinate geometry.
Mensuration and Trigonometry often appear tricky, but a well-explained solutions book simplifies calculations by breaking them down into smaller steps. Students learn how to approach volume and surface area problems using systematic formulas and derivations. Trigonometry is introduced with fundamental identities, and a step-by-step approach to sine, cosine, and tangent functions makes it easier to grasp.
Probability and Statistics introduce students to data handling and analysis. Solution books provide real-life examples to explain how probability works in practical situations, from rolling dice to analyzing survey data. A structured approach to calculating mean, median, and mode ensures that students gain a clear understanding of statistical concepts.
Having access to well-explained solutions allows students to prepare effectively for exams. Many books include additional practice questions, previous year’s question papers, and mock tests. These help students get familiar with the exam pattern, improve their time management skills, and identify their weak areas for improvement.
Apart from textbook solutions, several books also focus on conceptual learning through real-world applications. This not only makes Mathematics interesting but also helps students relate mathematical concepts to everyday situations. Understanding the relevance of these topics in fields like engineering, economics, and data science encourages students to develop a deeper appreciation for the subject.
A well-structured Mathematics solution book isn’t just about finding the right answers—it’s about understanding the "why" behind each solution. Clear explanations, multiple solution methods, and interactive exercises help students become independent problem solvers. Whether it's algebraic expressions, coordinate geometry, or probability, a reliable guide ensures that students grasp every concept with clarity and ease
