Answer 1

Answer:

25 Girls.

Step-by-step explanation:

Total no. of students= 90 Out of which 45 are boys which means 45 are girls.

Now, Students who got A grade = 90×50/100

=45

So 45 students got A grade marks

Out of which 20 are boys which means girls who got A grade = 45-20=25

Hence, 25 Girls got A grade.
