Solution
4 men and 4 women to be seated alternatively.
We can have men in the odd places and women in the even places: M W M W M W M W
Arrangements for Men = 4 * 3 * 2 * 1 = 24
Arrangements for Women = 4 * 3 * 2 * 1 = 24
Total arrangements for the above = 24 * 24 = 576
Similarly we can have 576 arrangements for women in the odd places and men in the even places: W M W M W M W M
Therefore total arrangements = 576 + 576 = 1152
