thanks for ur response...but this is not right ans...there is repeatition of s and p.So the right ans is 8!/4! .2!×4!
as you not mentioned Repetation is allowed
so
okk I accept that I had not mentioned that repeatition is allowed but ur answer is not right also now...bcoz if repetition is not allowed then then the answer will be 4!.3!
no
why no...the letters of M ,S and P are taken only once if repetition is not allowed
no
