Correct Answer: 50400
Explanation:
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.
