Câu 1 : Nhà thông thái đó đã suy luận như sau :
- Ai cũng cười vì tưởng trán mình không nhọ , hai người kia thì cười nhau còn mình thì cười họ.
- Thế nhưng , nếu trán tôi không nhọ thì hai người kia đều sẽ phát hiện được ngay trán mình bị nhọ. Chẳng hạn người thứ ba , khi thấy người thứ hai cười anh ta biết ngay là cười anh ta chứ không phải cười tôi ( vì tôi không bị nhọ ).
- Trong thực tế hai người kia đều cười và không phát hiện ra trán mình bị nhọ. Vậy trán tôi cũng bị nhọ.
Câu 2 : Cô đầu bạn hỏi là cô : Nhị
Cô nói xen vào là cô : Nhất
Hôm đó là thứ : Ba
Nội quy khi tham gia OLM math:
