In just a few moments, a person who has never once lost an argument is about to be completely undone by a photograph. They will look at it with the relaxed confidence of someone who considers themselves sharp, observant, and generally ahead of the curve, but that feeling won't last. This is what puzzles do to people, and this is exactly why we love them.

The human brain is a spectacular piece of machinery that is also, under the right circumstances, catastrophically easy to fool. A cleverly hidden object, a manipulated image, a pattern that refuses to resolve itself no matter how hard you stare, and suddenly the most intelligent person in the room is leaning three inches from their screen, muttering to themselves.

    If it shifts from, say, 01:14 to 01:15, are those 1s "appearing" again? (As in, how many four-digit times have some 1s and how many?) Or does "appear" mean how many times does it "roll.over" to a new 1? 🤓 And is it 12 hour digital or 24 hour display? And other annoying questions...🙃

    I'm getting 51962. My reasoning: The top line has a dot at the upper left, so all symbols with the dots above or to the left correspond to numbers on the top line. The bottom line, with the dot on the lower right, works similarly with dots below or to the right of the symbols. If the dot is to the side of the symbol, you take its reflection over the vertical axis (or flip it over sideways) to get the value on the appropriate line. Vertical symbols need two steps. First, you reflect the symbol over the horizontal axis (or flip it over vertically). Then you rotate it 90 degrees so that the little line is pointing up, if the dot was on the bottom, or down, if the dot was on the top.

    I was taught how to calculate this in a very rushed blackboard session in high school, right before a math meet, so I will pass it on. When mass is not distributed equally over a balance, you calculate the moment of each mass by multiplying its weight by the distance from the pivot point. Here, to balance the lower left bar, the "?" must be 2, because the two weights are equidistant from the pivot point. To balance the lower right bar, that "?" must be 1, so that its moment (weight * distance, thus 1 * 2) equals the moment on its left side (2 * 1). The top bar has a moment of 12 (4 * 3) on its left side, and a known moment of 9 (3 * 3) on its right. The moment of the highlighted mass must be 3 in order to even it out, and since it is only 1 unit away from the pivot, its weight must also be 3.

    This is from the children’s menu of Moose’s Tooth in Anchorage, AK, and is a variant of the classic “think outside the box” puzzle. In order to connect all the dots, using only 4 lines, the average dots per line must be 4, but I can’t figure out how to do more than 3 new dots for any line after the first (assuming every line touches at least 1 dot). I think that the directions must have a typo, or that there should a no solution. Any way to solve using the provided directions?

    There is at least one hat of each color. If C saw two black hats or two white ones on A and B, he could answer correctly immediately about his hat's color, choosing the one he had not seen. The fact that C does not answer immediately tells A and B that their hats are of different colors. So B knows that if A wears a black hat then he (B) is wearing a white and vice versa.

    Metaldrake Report

    bazjack
    Community Member
    3 months ago

    The poor reproduction here makes it hard to see, but I think the five identical rectangles are four lying on their long sides, touching each corner, and a fifth balanced on its short side in the middle. Let's say that those little rectangles are x wide and y tall, with x >= y. Length DC is therefore equal to 2x + y, which equals 20cm. Length AD is equal to both x and to 2y. Using substitution gives us (2 * (2y)) + y = 20cm, or 4y + y = 20cm, or 5y = 20cm, or y = 4cm. The area of a triangle is 0.5bh, or half of the base times the height. Since length DC is 20 cm and length AD is 8cm, the area of any triangle with two points at A and D and the third point touching line BC will be 0.5 * 8cm * 20cm, or 80cm^2, which is happily one of our answer choices.
