- 20%
- 100/3%
- 15%
- 40%

3. If 10 students come by car, how many come by bus ?

- 60
- 50
- 30
- 100

4. If 180 students come walking to school what is the strength of the school ?

- 540
- 450
- 360
- 600

**1. Answer: **144^{0}

**Explanation:-**

The total angle of the circle = 360 degree

The sum of the angle of the children who used transport = 120 + 72 + 24

= 216 degree

** ** The angle at the center representing people walking = 360 – 216

= 144 degree

Hence, the answer is (1) 144^{0}

**2. Answer: (1) 20%**

**Explanation:- **The angle of children whose are using scooter = 72 degree

Then, the percentage of children using scooter = 72 x 100/360

= 20%

Hence, the answer is (1) 20%.

**3. Answer: (2) 50**

**Explanation:- **If 10 students come by car,

Then, the angle of students are come by car = 24 degree

The angle of students are come by bus = 120 = 24 x 5

Then, the number of students are come by bus = 10 x 5

= 50

Hence, the answer is (2) 50.

**4. Answer: (2) 450**

**Explanation:- **If 180 students come walking to school ,

Then, the total number of students in the school = 180 x 360/144

= 450

Hence, the answer is (2) 450.
