The number of students takings neither of the juices is

Therefore the answer is 75 students

Answer 2

Solution:

Total number of students in a school = 400
Number of students taking apple juice = 100
Number of students taking orange juice = 150
Number of students taking both juices = 75
Total number of students taking apple juice, orange juice and both = (100 + 150 + 75) = 325 students
Number of students not taking apple juice neither orange juice = (400 - 325) = 75 students
