In how many ways can the letters of wordELECTRICALbe arranged such that all the Consonants always appear together?  Choose the most appropriate option:
A) 9!	B) 5!*4!	C) 5!*6!	D) 5!*4!*2!	E) 6!*4!
Let the arrangment be: _ _ _ _ _ _ _ _ _ _ (10 letters, 4 vowels E, E, I, A and 6 consonant L, C, T, R, C, L)   For all consonants together, consider them as 1 group {L, C, T, R, C, L} E E I A --&gt; this gives us 5! arrangements with {} group considered as 1 . Now {} group can in itself be arranged in 6! ways   Thus total arrangements with all consonants together = 5!*6! --&gt; 5!*6! is the correct answer.
