Question

Find the no. Of ways in which letters of the word valedictory

Answer 1

There are 4 vowels and 7 consonants in VALEDICTORY. If these have to be kept together, we have to consider AEIO as one letter. Then the problem transforms itself into arranging 8 letters among themselves (8! ways). Besides we have to look at the internal arrangement of the 4 vowels among themselves. (4! ways).
