We know that: 
Now, we have mean of 6 people that is 17
We know the age of 5 people while age of one person is unknown.
Let age of person which is unknown= x
So, we can write:
Sum of all data values = 17+16+ 15+ 17+ 22+x
where x is the age of person who enters the room.
Finding x

So, we get the value of x: x=15
Therefore, the age of the person who entered the room is 15.
