If the letters of the word SACHIN are arranged in all possible ways and these words are written out as in a dictionary, then the word SACHIN appears at serial number Correct Answer 601
The words are arranged as in a dictionary. So the words start with A comes first and then words start with C, H, I, N and at last words start with S will come.
If the word started with the letter ‘A’ then the remaining 5 positions can be filled in 5! Ways.
In the same way, the words started with C, H, I, N can be filled in 5! Ways each.
Total words can be arranged before arranging the words starting with ‘S’ = 5 × 5! = 600
Now, if we start arranging words starting with ‘S’, the first word will be SACHIN.
Hence the word SACHIN appears at serial number 601.
