​

Answer 1

Answer:

200

Step-by-step explanation:

Let the no. of total children in a school be x

No. of boys in the school= 3/5of the children= 3/5×x=3x/5

No. of girls in the school= 800

A/q

x= 3x/5+800

x-3x/5=800

x×5/1×5-3x×1/5×1=800

5x/5-3x/5=800

2x/5=800

2x=800×5

2x=4000

x=4000/2

x=2000

No. of boys in the school= 2000
