Answer 1

Answer:

D. 95%

Solution:

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 $= (\frac{57}{60})\times{100}$= 95% 

∴ The pass percentage of class 4 is 95%
