lheiannie07 wrote:What percent of Jefferson high school students study German?
(1) Of the male students enrolled at Jefferson high school 20 percent study German.
(2) Of the female students enrolled at Jefferson high school 35 percent study German.
Statements combined:
Case 1: Jefferson High consists of 20 male students and 80 female students, for a total of 100 students
Number of male students who study German = 20% of 20 = 4.
Number of female students who study German = 35% of 80 = 28.
(students who study German)/(total students) = (2+28)/100 = 30/100 = 30%.
Case 2: Jefferson High consists of 80 male students and 20 female students, for a total of 100 students
Number of male students who study German = 20% of 80 = 16.
Number of female students who study German = 35% of 20 = 7.
(students who study German)/(total students) = (16+7)/100 = 23/100 = 23%.
Since the percentage who study German can be different values, the two statements combined are INSUFFICIENT.
