Dear Student,
Vowels in the word = E , I , O , E (4)
Total number of letters in the word = 11
Now, consider all the vowels as one letter
Therefore total number of letters = 8
Total number of word that can be formed when vowels are together = x 9C4 (After arranging letters except vowels there will be 9 gaps where vowels can be inserted
=
=
= 846720
