Let's say there is a TOTAL of 100 students at this college.
50 percent of the total number of students are freshmen.
# of freshmen = 50% of 100 = 50
20 percent of the fresh-men are enrolled in the school of liberal arts...
Number of liberal arts freshmen = 20% of 50 = 10
...and, of these, 30 percent are psychology majors...
Number of liberal arts freshmen who are psychology majors = 30% of 10 = 3
What percent of the students at the college are freshmen psychology majors enrolled in the school of liberal arts?
3/100 = 3%
Answer: A

consider total number of students as 100
freshman students are 50% = 50 students
freshman enrolled in liberal arts = 20% of 50 = 10 students
freshman enrolled in liberal arts for psychology majors = 30 % of 10 = 3 students
percent of students at college who are freshmen psychology majors enrolled in the school of liberal arts = (3/100) * 100 = 3%
correct answer option A
freshman students are 50% = 50 students
freshman enrolled in liberal arts = 20% of 50 = 10 students
freshman enrolled in liberal arts for psychology majors = 30 % of 10 = 3 students
percent of students at college who are freshmen psychology majors enrolled in the school of liberal arts = (3/100) * 100 = 3%
correct answer option A
