In this paper, by giving an example we answer positively the question \Does there exist a P -primary ideal I in a Noetherian domain R such that PI = I 2 , but I is not almost prime?", asked by S. M. Bhatwadekar and P. K. Sharma. We also investigated conditions under which the answer to the above mentioned question is negative.
