## 47.

One day, Alice met the Lion and the Unicorn resting under a tree. They made the following statements.

Lion. Yesterday was one of the days when I lie.

Unicorn. Yesterday was one of the days when I also lie.

From these two statements, Alice (a very smart girl) was able to deduce what day of the week it was yesterday. What day was it?
47. The Lion could say that he lied the day before only on Monday and Thursday. The Unicorn could say that he lied the day before only on Thursday and Sunday. Therefore, they could both claim that they lied the day before only on Thursday.
