Given that,

There are 4 men and 4 women attending a conference meeting at a round table.

The number of ways 4 men and 4 women attend a meeting is 4!

Thus, the number of ways the men and the women were assigned alternate seats is 

\left ( 4-1 \right )!\times 4!=3!\times 4!

Therefore, the possible number of ways is 144.
