If n is an integer between 100 and 900, what is the tens digit of n?
(1) If n is rounded to the nearest ten and the result is then rounded to the nearest hundred, the final value differs from the result of rounding n to the nearest hundred.
(2) The tens digit of n is half the units digit of n and is twice the hundreds digit of n.
