If the word started with the letter A then the remaining 5 positions can be filled in 5! Ways.



If it started with c then the remaining 5 positions can be filled in 5! Ways.Similarly if it started with H,I,N the remaining 5 positions can be filled in 5! Ways.



If it started with S then the remaining position can be filled with A,C,H,I,N in alphabetical order as on dictionary.
