Number of words before COCHIN will be 96.On arranging letters in alphabetical order,CC(----) = 4! Since 4 letters are written keeping CC fixed.CH(----) = 4!CI(----) = 4!CN(----) = 4!After these words, next word will be COCHIN.Therefore total words before COCHIN = 4×4!Hence total words before COCHIN = 96.
