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

Solution

The word software can be split as
Vowels O A E
Consonants S F T W R

These can be arranged in 6! ways. But there will also be internal arrangement among A E O. This will happen in 3! ways.
