1 2 3 4 5 6 7 8 9 10 11 12
imagine each of the above as seats with named with numbers. we could start the row from 1 or 2 or 3 or 4 or 5 and still 8 people would fit the row. remember, there are no spaces between them. so we have 5 options to start from. again within each arrangement, the people could be positioned in 8! or 8P8 ways
so the answer is 5*8!

The site was down. My paper went awesome.. it was quite easy actually.. compared to papers of 2010 and 2011.. If I hadn't misread a question and remembered what I had to do in that n and k question I would have gotten 50/50
but oh well.. Insha Allah should get around 40 or so. You?
