Let the total number of students be a
Number of girls + Number of boys = Total number of students
=> 3a/5 + 200 = a
=> a - 3a/5 = 200
=> 2a / 5 = 200
=> a = 200 ×5 / 2
=> a = 100 × 5
=> a = 500
Total number of students = 500
Number of girls + Number of boys = Total number of students
=> 3a/5 + 200 = a

=> a = 100 × 5

Let the total no. Of students be x
According to ques.
3/5 of x + 200=x
3/5x+200=x
200=x-3/5x
200=5x-3x/5
200=2x/5
200×5=2x
1000/2=x
500=x
I will verify it also for u
Now no. Of girls =3/5×500
=300
And no of boys given =200
So total =500
