ANSWER=20/3

Step-by-step explanation:

Answer 2

One day work of 6 men or 12 women or 18 children is  $\frac{1}{30}$

One day work of 6 men, 12 women and 18 children $=\frac{1}{30}+\frac{1}{30}+\frac{1}{30}$

$=\frac{1+1+1}{30}\\=\frac{3}{30}\\=\frac{1}{10}$

one day work of 6 men, 12 women and 18 children$=\frac{1}{10}$

Hence, in 10 days work will be finished by 6 men, 12 women and 18 children.
