The word 'SINGING' has 7 different letters.   When the vowels II are always together, they can be supposed to form one letter.   Then, we have to arrange the letters SNGNG (II).   Now, 6 (5 + 1 = 6) letters can be arranged in 6! = 720 ways.   The vowels (II) can be arranged among themselves in 1! = 1 way.   Required number of ways = (720 x 1) = 720.   ANSWER:720
