Number Properties

[swerve]

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 \(n\).
