Question

Frame the equation and solve:

The total number of students in a school is 2100. If the number of boys are 210 more than the number of girls. Find the number of boys and girls.

Answer 1

$\boxed{#ANSWER....!!!}$

Let the number of girls be 'x'..

Then the number of boys will be x + 210.

The total number of students in the school is 2100.

Equation -:

x + x + 210 = 2100

Now solving the equation ,

2x + 210 = 2100

2x = 2100-210

2x = 1890

x = 1890/2

x = 945

Now ,

The number of girls in the school = x

= 945

The number of boys in the school =
x + 210

= 945 + 210

= 1155...

Now , verifying the equation,

No. of girls + no. of boys = 2100

945 + 1155 = 2100

2100 = 2100..

:)

Answer 2

let the number of girls = x
so , the no of boys =210 more than girls
=x+x+210
x+x+210=2100
2x+210=2100
2x=2100-210
2x=1890
x=1890÷2
x=945

so, the no of girls in school =945
hence, the no of boys is = 945+210
=1155
