Time for a new math puzzle.
Alice lives on the south side of a long street.
On the south side, all of the houses have even numbers: 2, 4, 6, ...
Alice's house number has three digits.
Alice, who is compulsive about numbers, says, "The sum of the even house numbers on this street below mine is exactly equal to the sum of the even house numbers on this street above mine! Moreover, this common sum is just one less than my zip code."
a) What is Alice's house number?
b) What is the highest even house number on this street?
c) Where does Alice live?
Solution will be posted in one week if nobody solves it.
