Consider the word UNBIASED. How many words can be formed with the letters of the
word in which no two vowels are together?
If we arrange consonant first it will be:-
4*3*2*1 = 24
Now we are arrange 4 vowels as:-
X C X C X C X C X
Permutation of 5 objects taken 4 at a time. 5! = 120
Answer is coming to be 120 * 24 = 2880
But the actual answer is different.
