Answer 2

Step-by-step explanation:

Given: According to the given pie chart about Number of students, nationwide, it can be inferred,

⇒ Indian students = 180°

⇒ American students = 90°

⇒ African students = 45°

⇒ Others = 45°

To Find: The Percentage of ,

⇒ Indian students

⇒ African students

We know, The angle made by a circle is 360°

So,

⇒ The fraction of Indian students = $\frac{180}{360}$

⇒ $\frac{1}{2}$

⇒ Percentage = $\frac{1}{2}\times100$%

⇒ $50$%

Hence, the percentage of Indian students = $50$%

⇒ The fraction of African students = $\frac{45}{360}$

⇒ $\frac{1}{8}$

⇒ Percentage = $\frac{1}{8}\times100$

⇒ $12.5$%

Hence, the percentage of African Students = $12.5$%
