In a city, 30% are females, 40% are males and remaining are children. What per cent are children?

Dear Student

From the question, it is given that
Percentage of female in a city =30%
Percentage of male in a city = 40%
Total percentage of male and female both = 40% + 30%
= 70%
Now we have to find the percentage of children = 100–70
= 30%
So, 30% are children.

Thanks
