Of the 230 single-family homes built in City X last year, how many were occupied at the end of the year?

(1) Of all single-family homes in City X, 90 percent were occupied at the end of last year.

(2) A total of 7,200 single-family homes in City X were occupied at the end of last year.

这题为啥选C?230在题目中起了什么作用?

还顺便问一句,是不是0也是偶数?

条件1,2结合可以算出有6480=7200*90%.还望指教!

0即不是偶数也不是奇数
