Question

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

Answer 1

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)

60/100 ×(x+812)=x

3/5(x+812)=x

3x+2436=5x

2x=2436

x=1218
