S T S T S = TOTAL 5

NO. OF ARRANGEMENT = 5-1! = 4! = 24.

Dude the ans is 6
because there are 5 people out of them 1 is the tallest and 1 is the shortest .... since they sit always together we consider those 2 ppl as 1 ....... so the total no. of people will become 4 and these 4 can be arranged around a round table in 3! ways i.e 6(circular permutations)
