Dear Student,
The number of words starting with the letter ‘e’ = 5! = 120
The number of words starting with the letter ‘h’ = 5! = 120
The number of words starting with the letter ‘m’ = 5! = 120
The number of words starting with the letter ‘oe’ = 4! = 24
The number of words starting with the letter ‘oh’ = 4! = 24
So adding the above we get the first word starting with ‘om’ will have the rank 409 which is the word ‘omehrt’
So the word which will have the rank 412 is ‘omerth’,
Hope it helps!
