## Sample Maths Questions for Class 9 with Answers

Solve Maths Questions for Class 9 of number systems, polynomial equations, coordinate geometry, lines and angles, triangles, quadratic equations, menstruation, statistics, and probability.

### Number Systems

1. **Simplify:** 3√27×3√8

**Solution:** 3×2=6

2. **Rationalize the denominator:** 1/(√5−2)

**Solution:** √5+2 / (√5−2)(√5+2) = √5−4/5+2 = √5+2

### Polynomials

3. **Find the product:** (x+3)(x−2)

**Solution:** x^{2}−2x+3x−6 = x^{2}+x−6

4. **Factorize:** x^{2}−9

**Solution:** (x+3)(x−3)

5. **Divide:** (x^{3}−3x^{2}+2x+5)÷(x−2)

**Solution:** Using synthetic division, we get a quotient of x^{2}−x+1 and a remainder of 7.

### Coordinate Geometry

6. **Find the distance between points A(2, 3) and B(5, 7).**

**Solution:** d = √(5−2)^{2}+(7−3)^{2} = √9+16 = 5

7. **Find the midpoint of the line segment joining points A(3, 5) and B(7, 9).**

**Solution:** M=((3+7)/2,(5+9)/2) = (5,7)

### Lines and Angles

8. **If two lines intersect, prove that the vertically opposite angles are equal.**

**Solution:** This is a standard geometry proof that involves using the properties of linear pairs and adjacent angles.

9. **If the angles in a triangle are in the ratio 2:3:7, find the angles.**

**Solution:** Let the angles be 2x, 3x, and 7x. Since the sum of angles in a triangle is 180°, we get 12x = 180, so x = 15. Therefore, the angles are 30°, 45°, and 105°.

### Triangles

10. **In a right-angled triangle, the hypotenuse is 13 cm and one of the legs is 5 cm. Find the length of the other leg.**

**Solution:** Using the Pythagorean theorem, we get a^{2}+5^{2}=132, so a^{2}=144 and a = 12 cm.

11. **Prove that the angles opposite to equal sides of an isosceles triangle are equal.**

**Solution:** This is another standard geometry proof that involves drawing a perpendicular bisector of the base.

### Quadratic Equations

13. **Solve the quadratic equation:** x^{2}−5x+6=0

**Solution:** Factoring, we get (x−2)(x−3)=0, so x = 2 or x = 3.

14. **Find the discriminant of the quadratic equation:** 2x^{2}−3x+1=0

**Solution:** The discriminant is b^{2}−4ac=(−3)^{2}−4(2)(1)=1.

### Area of Parallelogram and Triangle

15. **Find the area of a parallelogram with base 12 cm and height 8 cm.**

**Solution:** Area = base × height = 12 cm × 8 cm = 96 cm²

16. **The area of a triangle is 24 cm². If the base is 8 cm, find the height.**

**Solution:** Height = (2 × Area) / base = (2 × 24 cm²) / 8 cm = 6 cm

### Mensuration

17. **Find the volume of a cube with a side 5 cm.**

**Solution:** Volume = side³ = 5³ cm³ = 125 cm³

18. **Find the total surface area of a sphere with a radius 7 cm.**

**Solution:** Total surface area = 4πr² = 4 × π × 7² cm² = 616π cm²

### Statistics

19. **Find the mean, median, and mode of the data: 2, 4, 5, 3, 2, 5, 4, 6.**

**Solution:** Mean = (2+4+5+3+2+5+4+6)/8 = 3.75, Median = 4, Mode = 4 and 5.

20. **Draw a histogram for the following frequency distribution:**

| Class Interval | Frequency | |—|—| | 0-10 | 5 | | 10-20 | 8 | | 20-30 | 12 | | 30-40 | 6 |

**Solution:** A histogram can be drawn using the given data, with the x-axis representing the class intervals and the y-axis representing the frequency.

### Probability

21. **A coin is tossed twice. Find the probability of getting two heads.**

**Solution:** The total possible outcomes are HH, HT, TH, and TT. The probability of getting two heads is 1/4.
