. In how many different ways can the letters of the word 'LEADING' be arranged in such a way that the vowels always come together?
(a) 360 (b) 480 (c) 720 (d) 5040

• Ans : 5!*3!=720
  Vowels in letter are {A,E,I}.since vowels came together
  Arrangement will be {(A,E,I),L,D,N,G}
  here the arrangement will be 5! and (A,E,I) itself arrange in 3 ways hence 5!*3! =720
