Answer provided by our tutors
Let 'm', 'w', and 'c' stand for the number of men, women, and children, respectively. We can write:
2m+.7w+.30c=20
m+w+c=20
This leaves us with 2 equations and 3 unknowns. We need another equation to solve this system. Therefore, without more information, this question is unsolvable.
