10% of students = 240/3=80 students
70%=7x80=560 boys
total no of students = 70%+30%=560+240=800 students

Answer 2

Hey user here is your answer
___________________________

✅let the total students be x

✔️Number of girls =240

✅Number of boys= x-240

◆Total students - 240 = Number of boys

✅if 70% students in a school are boys then rest are girls that is 30%

✔️30%x=240

✅30x/100=240

✅30x=240×100

✔️30x=24000

✅x=24000/30

✔️x=800

⭕️Total number of students are 800

⭕️Total number of boys =total students -240

⭕️total number of boys=800-240

⭕️Total number of boys= 560
