Question

if 50% of the school students are girls.find the total number of students,if the numbers of boys are 180

Answer 1

if 50 % of total is number of girls then boys are also 50 %
so , 50 / 100 × total number of students = 180
total number of students = 360

Answer 2

50% of school students are girls => Remaining 50% are boys.
=> No. of Girls = No. of Boys.
Given that no. of boys = 180.
=> No. of Girls = 180
Total no. of students = No. of girls+ No. of boys
=> Total no of students = 180 + 180 = 360
