Question

plzz answer Qno.10 it's very urgent ...

Answer 1

hello,
no. of boys in class is 30 and no. of girls in class is 25
total no. of students in class is 30+25=55
let the percentage be x%
therefore x% of 55=30  (x% of total = value of x)
x%*55=30
x/100=30/55
x/100=6/11
x=(6/11) * 100
x=54(approx.)
therefore percentage of boys in class is about 54%
