Answer 1

Step-by-step explanation:

Question:-

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

Answer:-

Given:-

• 60% of the students are boys.
• Girl's number is 812.

To find:-

• numbers of boys in the school

Solution:-

Let number of boys be x and number of percent 60%

if 60% are boys in a school

then, 40% are girls in a school

Total amount of students = (x + 812)

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

$= \frac{60}{100} ×(x+812) \: =x$

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

$= \: 3x+2436=5x$

$= \: 2x=2436$

$= \: x=1218$

• Hence, the number of boys are 1218.
