不好意思，貌似是写在300后那一份讨论稿里的，昨天刚刚看到201-300，抱歉添麻烦 ...

sorry,我以为我在201-300写了，记错了，不好意思。

我认为是的。因为1和2一起是推出-1

Excuse me Lou Zhu:
Why x cannot=1?
After discussed x>1 and x>1, I tried x=1 and it also fits.

(sorry can't type in Chinese)

That's OK.
x could be 1. you should read my explanation about question274
I wrote -1<X<4, so yes, X could be 1

239.
不知道我这个解题思路对不对。
2500*X + 5000*Y + 150*Z = 7500

如果是整数的话倒是可以哦~考场上再看吧！
