Question

a total of 1800people gathered in an auditorium. 11/24of them were women and 7/18of them were men. the remaining of them were children. what fraction of them were children and how many children were present in the auditorium

Answer 1

(11/24)×(1800)=825 i.e women are 825
(7/18)×(1800)=700 i.e men are 700
So 1800-825+700=275 i.e children are 275
