Bheja fry question

 This bheja fry question I heard it recently on web radio.

Question 

2 ducks in front of a duck, 2 ducks behind a duck and a duck in the middle. How many ducks are there ??

Answer 

If we go by word to word as given on the question, we end up with answer as  5 ducks. 

But we can still think of one more probability. 

This answer meets the above said requirements suitably. 

             Total ducks are     3   !!!!

If we refer to last duck, there are 2 more ducks in front of it.

If we refer to first duck, there are 2 more ducks at the back. 

Still one duck at the centre  !!!!
