Answer 1

Answer:

Number of boys = 450, and

Number of girls = 360.

Step-by-step:

5x + 4x = 810

9x = 810

x = 810/9

x = 90

Therefore, value of x = 90.

So, number of boys = 5x

= 5 x 90

= 450

Now, number of girls = 4x

= 4 x 90

= 360.

Hence proved.

Step-by-step explanation:

It is easy 5x+4x = 810

so 9x=810

x= 90

5x= 450

4x=360
