Question 1207384
<pre>
The number of men must be a multiple of 6.  So let there be 6N men. 
1/6 of 6N men or 1N men are single and the other 5N men are married.
So 5N women are married to those 5N men, and since 1/2 the women are
single, 1/2 the women, or 5N are married, so another 5N women are single.

So the ratio of married to total people is 

{{{(5N+5N)/(5N+5N+N+5N)= (5+5)/(5+5+1+5)=10/16= 5/8=0.625="62.5%"}}}
