## Lion and the Unicorn

Logic puzzles require you to think. You will have to be logical in your reasoning.

 Puzzle ID: #48970 Fun: (2.9) Difficulty: (1.18) Category: Logic Submitted By: Faith511

Alice came across a lion and a unicorn in a forest of forgetfulness. Those two are strange beings. The lion lies every Monday, Tuesday and Wednesday and the other days he speaks the truth. The unicorn lies on Thursdays, Fridays and Saturdays, however the other days of the week he speaks the truth.

Lion: Yesterday I was lying.
Unicorn: So was I.

On which day did they say that?

As there is no day when both of the beings would be lying, at least one of them must have spoken the truth. They both speak the truth only on Sunday. However, the Lion would then be lying in his statement, so it couldn't be said on Sunday. So exactly one of them lied.

If the Unicorn was honest, then it would have to be Sunday - but previously we proved this wrong. Thus only the Lion spoke the truth when he met Alice on Thursday and spoke with the Unicorn about Wednesday.

 Thekid4 Aug 23, 2011 yay! first time I ever got first comment! oh, and I got it correct. kittygirl19 Aug 24, 2011 Truthful unicorn is the answer. Vengeance101 Aug 26, 2011 It was fun, but I think it could have been more challenging with more characters. Good job, all the same. juggler314 Aug 28, 2011 Piece of cake! JQPublic Aug 30, 2011 Easy but good. Shadows Sep 04, 2011 I read this one in a book a while ago. A very good and simple teaser. msufan84 Sep 19, 2011 That was confusing ? ? ? ? msufan84 Sep 19, 2011 Oh it was fun to...........confusing but fun. zembobo Nov 17, 2011 At first I said Sunday but then I thought about it and went through all the days. Thursday was the only one that fit. That was fun! oddrey Feb 21, 2012 Nice teaser. Pretty simple once you draw a quick chart, but still fun! I think the answer could have been written a little more clearly though. Babe May 24, 2012 WHAT???? spikethru4 May 24, 2012 I worked it out thusly: If the Lion is telling the truth, it must be Thursday. If he's lion, it must be Monday. If the Unicorn is telling the truth, it must be Saturday. If he's lying, it must be Thursday. So it's Thursday. The Unicorn's a-lyin', and the Lion isn't. HABS2933 May 24, 2012 Super easy. The way you explained the answer was much harder to follow than finding the answer was! tripleteam5 May 24, 2012 This was ok to figure out. BUT the answer was )(^%\$. Nowhere in the "answer " does it say that Thursday is correct answer. It cloudily implies that is answer. iggy39 May 24, 2012 I didn't like this one very much Sorry just didn't royale-ninja Jul 25, 2012 i figured it out markitude May 25, 2015 I agree. Teaser was good, but it could have been clearer in the answer that Thursday was correct. Oh and I got it right. raisin99 May 25, 2015 easy and fun, thanks
