In the word 'CORPORATION', we treat the vowels OOAIO as one letter.   Thus, we have CRPRTN (OOAIO).   This has 7 (6 + 1) letters of which R occurs 2 times and the rest are different.   Number of ways arranging these letters =	7!	= 2520.   2!   Now, 5 vowels in which O occurs 3 times and the rest are different, can be arranged   in	5!	= 20 ways.   3!   Required number of ways = (2520 x 20) = 50400.   50400
