Short Trick:
Total students = 900
Boys : Girls = 30 % : 70% = 3 : 7
So, exactly Boys : Girls = 270 : 630
Total failed students = 18% of 900 = 162
Failed boys = 30% of 270 = 81
Failed girls = 162 - 81 = 81
Passed female students = 630 - 81 =549
Basic Method:

⇒ Let us consider total number of students be 100x
⇒ ∴ Males students = 30x , female students = 70x
⇒ According to condition given in the problem, of this 30x male students, 70 % male students pass the exam.

900 students
30% boys, which is 270 boys
Rest 630 are girls.

Now no of passed students is 82%
That is 738 pass

which means 162 failed

If 30% of boys had failed... then it is 81
Thus no of failed girls is also 81

we have total no of girls and no of failed girls...
630-81= 549
