Answer:
40 part-time male students were in the survey.
Step-by-step explanation:
Given:
Total number of students in the Phoenix high school = 100
Number of female student = 40
Number of male student who went to Phoenix Full time = 20 students
Total number of full time students = 50 students
To Find:
Number of part time male students in the survey = ?
Solution:
we know that the total number of students = 100
Now total number of male students = total number of students - total number of female student
Now total number of male students = 100 - 40 = 60 students
Now among these 60 students, 20 males went to Phoenix
Full time
So the remaining male students = 60-20 =40 students
Hence these 40 students are part-time male students
