if the average score for the 25 students was 75, then the total score for all students had to be 25 * 75 = 1875.
if the average score for the 15 female students was 70, then the total score for the female students had to be 15 * 70 = 1050.
the total score for the male students had to be 1875 - 1050 = 825.
since there were 10 male students, then their average score had to be 825 / 10 = 82.5.
that should be selection c.
