The given chart shows the number of students in Class 4, Class 5, Class 6 and Class 7 who got first class, second class and failed in the final examinations. What is the pass percentage of Class 4? Correct Answer 95%

Given:

  First-class Second class Third class
Class 4 45 12 3
Class 5 38 15 7
Class 6 42 10 8
Class 7 30 25 5

Concept used:

Total number of student in class 4 = 45 + 12 + 3 = 60 

Number of student who passed in class 4 = 45 + 12 = 57 

Pass percentage of class 4 = (57/60) × 100 = 95% 

∴ The pass percentage of class 4 is 95%
