If ja means no, they both would still answer ja-in this case, False would answer the embedded question with ja, but saying da to the overall question would be telling the truth, so he says ja. What three questions do you ask to figure out who’s who?Īnswer: Before getting to the answer, let’s think of a hypothetical question you know the answer to, such as “Does two plus two equal four?” Then, phrase it so you’re asking it as an embedded question: “If I asked you if two plus two equals four, would you answer ja?” If ja means yes, Truth would answer ja, but so would False (he always lies, so he’d say ja even though he really would answer da). You can ask three questions to any of the gods (and you can ask the same god more than one question), and they will answer with ja or da. They understand English but answer in their own language, with ja or da for yes and no-but you don’t know which is which. We can call them Truth, False and Random. One always tells the truth, one always lies, and one tells the truth or lies randomly. Logic Puzzle: This conundrum, a variation on a lying/truth problem, has famously been called the hardest logic puzzle ever. Near Impossible Logic Puzzle for AdultsĢ5. But since Monty knows and shows you where one of the goats is, that 2/3 chance now rests solely with the third door (your choice retains its original 1/3 chance you were more likely to pick a goat to begin with). At the beginning, your choice starts out as a one in three chance of picking the car the two doors with goats contain 2/3 of the chance. Should you stick with your original choice or switch, if you want the car?Īnswer: You should switch. After you’ve chosen one but haven’t opened it, Monty, who knows where everything is, reveals the location of a goat from behind one of the other two doors. Named for the Let’s Make a Deal game show host, the puzzle goes like this: You are given three doors to choose from, one of which contains a car and the other two contain goats. Logic Puzzle: The “Monty Hall” problem was made famous when it appeared in Parade magazine’s “ Ask Marilyn” column in 1990, and it was so counterintuitive it had everyone from high school students to top mathematical minds questioning the answer-but rest assured, the solution is accurate.

This means if you check boxes 2, 3, and 4 in that order, you will find him within two rounds (one round of 2, 3, 4 followed by another round of 2, 3, 4). But if this is the case, you know that on the fourth night he’ll have to be in an even-numbered box (because he switches every night: odd, even, odd, even), so then you can start the process again as described above. If he was in an odd-numbered box to begin with (1, 3, or 5), though, you might not find him in that first round of checking boxes 2, 3 and 4. The next morning, check box 3 if he’s not there that means he was in box 5 and so the next night he’ll be in box 4, and you’ve got him. If he’s in an even box (box 2 or 4) and you check box 2 and here’s there, great if not you know he was in box 4, which means the next night he will move to box 3 or 5. Here’s why: He’s either in an odd or even-numbered box. How do you win this game of hide and seek?Īnswer: Check boxes 2, 3, and 4 in order until you find him. Every night he jumps to an adjacent box, and every morning you have one chance to open a box to find him. Logic Puzzle: You have five boxes in a row numbered 1 to 5, in which a cat is hiding.
