How many words can be formed from the letters of the word "ALTER", so that the vowels never comes together
We need to find the ways that vowels never come together.
Vowels are A, E
Let the word be LTR(AE) having 4 words.
Total ways = 4! = 24
Vowels can have total ways 2! = 2
Number of ways having vowel together = 48
Total number of words using all letter = 5! = 120
Number of words having vowels never together = 120-48
