The number of ways to n people on circular table is (n-1)!<\/p>\n
So, first we fix position of men, the number of ways to sit men = 5!<\/p>\n
Now, women can sit in the gaps between men, there are 6 gaps between 5 mens,<\/p>\n
So, women can sit in \\(^6P_5\\) ways<\/p>\n
Hence, total number of ways = 5! x \\(^6P_5\\) = 5! x 6!<\/p>\n
