Permutation(or the number of possible ways to rearrange a word) of a word

Question

we have to find number of ways by which we can arrange a word .
example
PUSHKAR
possible words are
USHKARP
SUKARPH
RAPUSKH
.
.
.
so on.
and you have to find number of ways like this.
BUT
be careful for the word which contain a letter which contain letter repeated
like in APPLE
here P is repeated. so this will decrease the number of words arrangement.
HINT :-
take help of permutations and combination of maths.this will help a lot.
Go for it.
