Question

If 60% of the students in a school are boys and the girls number is 812 , how many boys are there?

Note : pleas give the answer with steps.

Answer 1

it means 40% are girls
let the total students be x
40% of x = 812
40/100×x = 812
0.4x =812
x =812/0.4=2030
no. of boys = 60% of x = 60% of 2030= 0.6×2030 = 1218

Answer 2

Answer:

The number of boys is 1218.

Step-by-step explanation:

Let a number of boys are x and the number of percent 60% if 60% are boys in a school then, 40% are girls in a school.

The total amount of students $=(\mathrm{x}+812)$

60% of (x+812) is boys (x)

$&\frac{60}{100} \times(x+812)=x$

$&\frac{3}{5}(x+812)=x$

$&3 x+2436=5 x$

$&2 x=2436$

So,

$&x=1218$

The number of boys is 1218.
