Solution(By Examveda Team)
$$\frac{{{\text{5 men}} + {\text{2 women}}}}{{4{\text{work}}}}$$ = $$\left( {1{\text{ men}} + {\text{1 women}}} \right)$$$$5{\text{ men}} + {\text{2 women}}$$ = $${\text{4 men}} + {\text{4 women}}$$
$$\eqalign{ & {\text{1 men}} = {\text{2 women}} \cr & \frac{{{\text{Men}}}}{{{\text{Women}}}} = \frac{2}{1} \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{\text{M}}:{\text{W}} \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,2:1 \cr} $$
