Test Your Logic: Mind-Bending Puzzle You Can Solve In Your Head

[@yaduvarma9854]

Being a software tester allowed to me to get this right... 😅

[@relu1010]

Same :))

[@sofiyankhan-pj2ex]

Comparing with real life scenario was very helpful 👌

[@LOGICALLYYOURS]

That’s a great way to think about it!

[@noodle_fc]

The video does a good job of explaining the answer of this specific scenario. It would have been even better to generalize the solution for those not familiar with formal logic. Not just for cycles and licenses, but *every one-way condition* A -> B has a companion condition NOT B -> NOT A. That would elevate the video by adding some take-away knowledge to the fun.

[@LOGICALLYYOURS]

Thanks for your suggestion! That’s a great point about generalizing the solution for quick understanding. I must share your point in any of the upcoming videos.

[@BooksForever]

There’s a part of me that thinks if we can’t trust “the rule” we probably shouldn’t trust “the given” either, in which case we must also check the D for the presence of a vowel on the other side as a rule violation.

[@LOGICALLYYOURS]

I certainly understand your point. The given data can always be trusted. It’s only the “Rule” that needs to be verified…. At least in theory

[@Gideon_Judges6]

This is the issue I had with this puzzle as I've seen it or a small variation before. I get the intended solution, but practically if your factory can misprint even/odd numbers, it can misprint letter/number and end up with two letters, two numbers, maybe blank faces (out of ink), upside down or inverted images, etc... the separation of "given" and "rule" is kind of arbitrary and is not how QC is done in practice.

[@noodle_fc]

​@@Gideon_Judges6 But this isn't a video about how QC is done in practice. It's a logic puzzle. Logic puzzles contain arbitrary givens and rules. It delivered exactly what it promised but you're unhappy that it wasn't something else? If we're doing hypotheticals, just pretend there are people ahead of you on the QC pipeline who have already checked those other conditions. But really the best thing would be to take the puzzle as written because you're doing yourself no favors going to an Italian restaurant asking for Chinese food.

@@noodle_fc at the risk of sounding asinine, I did this once and got really good pasta dim sum! Though I think I may get banned if I keep pushing my luck 😂

@@noodle_fc not to be asinine, but I did do this once and got some really good pasta dim sums! But definitely did not do me any favours hahaha

[@kabir97]

Very well explained

[@LOGICALLYYOURS]

Thanks for the appreciation! 😊

[@DeepeshMaan]

You got me in this one, I underestimated the problem and thought only A should be flipped, next time i will be more cautious. Great explanation btw!

[@LOGICALLYYOURS]

I am glad you enjoyed the explanation!

[@Mallory16]

"Does a card with a Y need an even number on the other side?" "Sometimes!"

[@king-rz4li]

Cracked this. But provide answer to the last puzzle given in previous video

[@LOGICALLYYOURS]

I’m glad you solved it. The solution to archery 🏹 puzzle will be posted in 2 days.

[@vcvartak7111]

This is if A implies B is equivalent to ~B implies ~A . A card has to turn to see other side is even .and 7 has to turn to see it's not vowel. Listen to you after so many days

[@Smallpriest]

Imagine if it was a K instead of D 😂

[@LOGICALLYYOURS]

🤣 indeed it was originally K… i modified it to make it educational 😁

Google, what happened in AD 47? Google: In AD 47, the Romans established a settlement on the River Thames, a settlement that would become the city of Londinium. The settlement was situated at a bridgehead on the north bank of the river at a ford, where a major road nexus would converge at a bridge crossing

Yeah it was very easy.

Now I am actively working on posting puzzles :)

[@Horinius]

Yes, this is a very famous test: kzbin.info/www/bejne/n4OcaH94nNWmopo And thanks to this video, it makes me remember an even older video kzbin.info/www/bejne/jKCqhJ6PgaZmfZY Wow, that video is more than 16 years ago! I can't believe I saw it 16 years ago.

[@hikari1690]

Noooo, was waiting for the answer to the archery puzzle from last video 🥲. That said I grossly misunderstood the question. I thought the relationship was enforced both ways, i.e. if a card is vowel number is even, if number is even must he vowel and shouted "ah this puzzle is a trick! You need to flip all of them!"

[@LOGICALLYYOURS]

Haha, that’s a very common misunderstanding! Glad you finally got the puzzle. And the Archery puzzle solution will be posted tomorrow morning.

[@hikari1690]

@LOGICALLYYOURS yay! Thank you
