Q. Find the number of words that can be formed from the letters of the word FORTRAN if the two R’s are to be next to each other.
Solution:-
When the two R’s are next to each other then, the places left to fill remain 5
So,
5! = 120
Hence the required numbers of words are 120.
Answer by ramkikk66(644)   (Show Source):
You can put this solution on YOUR website! You missed one thing.
If you count the 2 R's as one letter, then there are actually 6 letters!
Hence they can be arranged in 6! = 720 ways.
Of course, the 2 R's can also be arranged in 2 ways, but since they are identical
letters, it does not count as a different word.
So the answer is 720 possible words and not 120.
Hope you got it :)
