大多數人的疑問

453. A,B,C三个人，问A=C?
1)A=40%B
2)B=250%C
选C

個人想問一個蠢問題  雖然答案算出來是A=C

如果算出來A不等於C 答案還是可以選擇C嗎 之前有聽NN講過NO也是一個答案

是的

如果判断大于小于什么的..NO也有可能是答案...

我也看到过某NN说多

Of course, it's a basic principle. You have to be sure that the statement in (1) or in (2) or in (1)(2) combined could lead to either a Y or an N answer to the question asked, then you could think it invalid. If they could ONLY lead to a Y or ONLY to an N, they are valid.
