Answer 1

Girls are=44%
Boys are=(100-44)=56%

Let Total student =x

Girls=44% of x
Boys=56% of x
Girls 6 less than Boys

A/Q

56% of x-6=44% of x

56%× x-6=44%× x
56/100×x-6=44/100×x
23x/50-6=11x/25
23x/50-11x/25=6 (lcm=50)
23x-22x/50=6
x/50=6
x=50×6
x=300

Total student=300
Here your answer
Thanks
