Question

School 4/7 of the students are boys if there are 210 girls find the number of boys in the school​

Answer 1

Answer:

Let total no. Of students be x.

Now boys=4x/7

Girls =210

So,total students =girls+boys

x=4x/7+210

x-4x/7=210

3x/7=210

3x=210×7

x=1470/3

x=490

So total no. of students =490

Boys=490-210=280

So, there are 280 boys in the class.

I HOPE THIS ANSWER IS HELPFUL!
