Explanation:

Solution:
9* 200 children = 18 * 150 men = 12 * 180 women
=>1800 children = 2700 men = 2160 women
=> 10 children = 15 men = 12 women
Now, 10 children + 3 men + 12 women
= 10 children + 2 children + 10 children = 22 children
=> 22 children can complete the work in = (200*9)/22 = 81(9/11) days
