in a class of 40 students, 80% are business majors. of the 24 students who passed the midterm exam, 75% are business majors. What percertange of students in the class who are not business majors passed the examination

80% of 40 = 32
So  8 students are not business majors.
75% of 24 = 18
So 6 nonbusiness majors passed the test.
What percentage is 6 out of 8?
