Question

30% of the population of a town are woman 55% are male and the remaining are children if the number of women are 15000 find the number of children in the town

Answer 1

Let x be the total no. of people
30% of x = 15000
x=50000
55% of x = 55% of 50000= 27500
hence no. of children = 50000-(27500+15000)=50000-42500=7500

Answer 2

let population of town be x
30/100×x=15000
x=15000×100/30
x=50000
children are 100-(30+55) =15%
no. of children =15/100×50000=7500
