As per alphabetical order first of all we get words starting with 'C'
'COCHIN' is one of the word in this group of words.
Before 'COCHIN' we get:
Words starting with CC = $4!=24\:words$
Words starting with CH = $4!=24\:words$
Words starting with CI = $4!=24\:words$
Words starting with CN = $4!=24\:words$
COCHIN comes next to these words.
The no. of words that appear before 'COCHIN' = $24+24+24+24=96$
