Given , number of Female students : 32
40% of the students were female
So, 40x/100 = 32
so, x=80 ... the number of students.
Thus , males = 80-32=48
As given that one third males were average .. this leads to below fact:
1/3 * 48 = 16 males were average.
Thus remaining 22 males are good.

Also given half the students are excellent or good as well as total 30 are good and 10 males are excellent. so number of excellent females = 0. Number of good females = 30 - 22 =8.
Number of average females = 32 - 8 - 0 = 24.
Total average students = 40
