Hey Sorry, there was a typo in the previous post and a correction..

Fix "3" at "third" position.
Number of ways would be : 3!*3!*2


Now, fix "3" at "fourth" position.
Number of ways would be : 4!*2!

Now, fix "3" at "fifth" position.
Number of ways would be 4!*2!.

Just add all of them to get total number of ways.
