ANSWER: C. 105
The simplest way to approach these problems is to divide the total number of students (189) by the combined ‘parts’ (5+4=9). Thus 189/9=21.
Multiply 21 by the gender of interest ratio (5): 21*5 = 105 male students
For females you would multiply 21 by 4 = 84 female students.
Add 105+84 to verify = 189
