gre power prep question

[karanc]

if n is an interger and 99 < n^2 < 200 , then n can have how many values

answer given in power prep is 10 which i feel is wrong as the correct answer is 5

since n is interger only 10,11,12,13,14 square fall between 99-200 so answer should be 5

please correct me how powerprep has given the answer as 10 ?
