"Class of 2018 graduates were 1250 students, 40% of them were female students, and the rest were male."

This means there were 500 female students and 750 male students in 2018.

"10% of the female students got a grade of “A” and 10 students of the female graded “A” were international students."

This means 50 female students got a grade of A in 2018, of which 10 were international students.

"Class of 2019 had 875 male students."

This means there were 375 female students in 2019. (It's later stated the total number of students (1250) hasn't changed since 2018.)

"10 female students got an “A” in their grade in class 2019."

10 female students got a grade of A in 2019. (Obviously.)

1. The number of Female students with a grade “A”.

50 + 10 = 60

2. The percentage of the female international students graded “A” out of the total number of female students with a grade “A”.

10/60 = 1/6 = 0.1667 = 16.67%

3. What is the percentage increase or decrease in the number of male students in comparison to class 2018?

= 125/750 = 1/6 = 0.1667 = +16.67%

4. What is the percentage of female students who got “A” out of the female students?

= 60/875 = 12/175 = 0.0686 = 6.86%
