Given the pie chart. Obtain the pass percentage of student who passed in 1st class. Correct Answer 25%

Given:

Students who passed in First class = 90° 

Total number of students = 360° 

Calculation:

⇒ Let us assume the total number of students is 360.

⇒ So the number of students who passed in first class = (90°/360°) × 360 = 90 students.

⇒ Percentage of students who passed in first class = 90/360 × 100 = 25%
