Question 1141507
The married couple can sit in 6 different positions, as follows: 
<pr>
OOXXXXX
XOOXXXX
XXOOXXX
XXXOOXX
XXXXOOX
XXXXXOO
<pr>
Also, in each of the above 6 positions, the husband and wife can swap places. So, in total, the married couple can sit at the table in 12 different ways.
<pr>
With the remaining 5 guests/positions at the table, they can sit in 5*4*3*2*1...or 120...different ways.
<pr>
The total ways the married couple can sit (12) multiplied by the total ways the other guests can sit (120) equals 1440.  
<pr>
So, a grand total of 1440 seating arrangements are possible.
