5 men and 2 women working together can do four times as much work per hour as a men and a women together. The work done by a men and a women should be in the ratio ?

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