Q91.	In how many different ways can the letters of the word �PREVIOUS� be arranged in such a way that the vowels always come together?

1)	2420	2)	2880
3)	3260	4)	4840
5)	None of these

Answer : 2880
Explanation :

Treating the group of four vowels (E, I O and U) as one distinct letter then total number of letters will be 8 - 4 + 1 = 5 [i.e. P, R, V, S and (E, I, O, U)].

The five letters can be arranged in 5! = 120 ways The vowels among themselves can be arranged in 4! = 24 ways,

The letters of the word �PREVIOUS� can be arranged in 120 � 24 = 2880 ways such that vowels always come together.
