Question
In how many different ways can the letters of the word 'LEADING' be arranged in such a way that the vowels always come together?A360B480C720D5040ENone of these
Solution
To solve this problem, we first consider the vowels EA and I as a single letter. So, we have the letters L, N, D, G, and 'vowel group' to arrange, which gives us 5! (5 factorial) ways to arrange these letters.
5! = 54321 = 120
Next, within the 'vowel group' of EA and I, we have 3! (3 factorial) ways to arrange these letters.
3! = 321 = 6
So, the total number of ways to arrange the letters in 'LEADING' such that the vowels always come together is 120*6 = 720.
Therefore, the answer is C720.
