5. There are equal number of boys and girls in a class. If 12 girls entered out, twice the boys as girls remain. What was the total number of students in a class?

• total number of students=2x
  boys=x
  girls=x
  x-12=x/2 (boys and girls are same if 12 are subtracted then girls become half)
  2x-24=x
  x=24
  tolat students=2x=2*24=48
  total students=48

• Initially let x boys and y girls are present.12 girls left y-12,now boys=x=2*(y-12).also x=y.answer is 48

• assume total number of boys=y
  total number of girls=x
  they given that equal number of girls and boys so x/y=1/1
  12 girls are entered out,
  x-12/y=1/2
  y=2x-24 (::x=y)
  x=2x-24
  x=24
  girls are x=24
  boys are y=x=24
  total number of students=x+y=>24+24=>48

• let boy=girl=n, 12 girls are out then it is half so total girls =12*2=24, so boys =24 then total student in class =24+24=48.

• no of boys and girls are 24
  total student =48

• let the no of boys is x and no of girls is y.
  Then,12 girls are entered out =y-12
  also x=2*(y-12)
  and x=y
  solving above equation we get x=24 and y=24
  hence total no of students is 48
