Permutations

S T S T S = TOTAL 5

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

Sry ..!!

But the options are

6   8   24 .. none of the above :)

They are sitting in a ROUND TABLE ..!!

STSTS cant be taken ..!

Tht shows Tallest is to left of shortest as well ..

U KNOW RIGHT & LEFT SIDE THEN U QUESTION?

it should be 24 i guess

(n-1)!

ie 4! =24

cheers

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)
