- After some feedback on my Mensa Norway IQ test video about people needing a better explanation for the 4 last puzzles, i decided to make four separate videos dedicated to each of the puzzles in case anyone needed it.
This is puzzle 35, which i explain first by text and then give a more visual explanation.
Please let me know in the comments if you find interesting IQ Tests that you want me to check out!

I found a different method. In each row, the first image on the left must have no identical lines with the 2nd and the 3rd picture. Only the 2nd and the 3rd picture of each row must have something in common. Therefore, D is the only solution. I liked your method too ;)
Ooh I like that method. It's simple and concise.
Nice way to cheat lol
You should really consider everything before having an answer that said I got every question right and I don’t for the life of me remember why I picked D
@@imthro1 Wrong. C has the horizontal line at the bottom which is common with the bottom left item. Therefore, only D can be correct.
@@imthro1that’s what I was left with too as my only two possible options after some time looking at the puzzle. However, the way I went about solving it was super rudimentary because I was too focused on looking for geometric patterns, or ways that the shapes could be manipulated in a way that would allow them to form other shapes. Anyways, what you’re saying makes sense, but from what he’s saying you need to have not only the triangle shape but the vertical lines as well, which immediately rules out C.
I got it correct, but I noticed a similar pattern with a very different method... these types of iq question can have multiple answers because there are many different logical patterns that can be more or less logicaly complex than the "correct" one or even more obvious/beautiful... therefore I wouldnt feel too bummed out, if I got a different solution
I agree but then again there are some people who find patterns in randomness OR people who base patterns on only 2 "points of information" which is equivalent to just drawing a line through 2 points and saying there is a pattern of these two points being on that specific line...
The solution provided, albeit quite elegant and intriguing, is inconsistent with Ockham’s razor principle. Generally, these type of itmes would not be appropriate in an actual test of cognitive abilities. In such a test there ought not be alternative solutions in addition to the one deemed correct by the test designer. See for instance Raven SPM and APM.
But Ockham's razor principle simply states that:
IF that two explanations give the same answer THEN the simplest explanation is probably the correct one. I think that this solution is the simplest solution you can find and I don't see how this goes against the principle.
Have you found a simpler way to come up with the same answer?
@@PuzzlesAndSolutions yes, there is a much simpler one. The first row can't have any same line as the 2nd and 3rd row but 2nd and 3rd must share at least one
@@PuzzlesAndSolutions About Ockam's razor, see Νικόλαος Χαλδεάκης's comment: "In each row, the first image on the left must have no identical lines with the 2nd and the 3rd picture. Only the 2nd and the 3rd picture of each row must have something in common. Therefore, D is the only solution."
I think the most probable answer is B since it can factor in why the first line of tiles didn't have two down ward facing triangles. My thinking is that for each row down the puzzle adds one extra figure and then plus the explanation you gave we can arrive at answer B.
Btw good videos
Sorry for the slow answer (vacation), What do you mean with "adds one extra figure"? Like adds one more figure in each of the rows? and we would have +2 shapes in the last row compared to the first if we had these shapes in our answer?
Ty for the feedback :P
@@PuzzlesAndSolutions correct
@@hansxu7085 The only problem I would have with this argument is that we only have "2 points of information". We only have the first and the second row. You could always draw a line between two points or a conclusion from two points of information therefore its not suficcient information.
I chose B as well
Glad I wasn’t the only one
Alternative way of getting to D: diaganols running down from left to right. Two of the lines repeat, and two of the lines rotate.
Not perfect as rotation degrees and pivot point are consistent/don't have a pattern
Not sure if this is lucky way of getting right answer
Hi, the pattern I saw is the following:
When stacking (combining) figures of each row, the outer rectangle created is a full rectangle with a double layer for the top line (the top line of the rectangle is repeated).
In the last row, what’s missing to reach this rule is thus:
- The two sides of the rectangle
- The top line to be repeated
The only answer fulfilling these requisites is E.
However I didn’t find any pattern for the diagonals so I’m not 100% sure.
I similarly saw E and that’s why I got it wrong. But for a slightly diff reason. Each row has one with 2 parallel horizontal lines, 1 horizontal line, and 2 parallel vertical lines. In order to get to that combo the answer is E.
I obviously see the pattern he sees now, but this one is pretty open ended.
If you look at the columns from left to right notice that the number of horizontal lines increase, 2 then 3 so the last column should have 4. Also no box is repeated inverted or not. Since E has the 2 vertical lines, the correct "V" and 1 horizontal line and is not a repetition of a another box it's the correct answer.
A is the exclusion of the union of B and C
I got this right and I feel very smart
Add each row and each column. The "spare" or "doubled" lines equate to a downward pointing triangle x 2. The top row leaves a top line only. The second row has a complete downward triangle. So the bottom row should leave only a V shape, which when added to what we have "spare" for the top row equals all of what you have "spare" in the second row (making two downward facing triangles). Same for the columns: First column has no "spare" lines. The second column has a complete downward facing triangle. So the third column has to have a complete downward facing triangle. (Extend each row and column by one box and see what you are left with once you remove all the lines that only appear once in each row or column). I have never thought to use the "diagonal pattern" method.
La tua spiegazione è chiara e mi ha convinto . Complimenti! :-)
Non parlo italiano, ma grazie :P
I see it from a different angle. If you stack the shapes horizontally, vertically, or diagonally you get the same exact shape. If you look at it from that angle, then F would be the sole solution
I followed your reasoning and was in agreement until 1:26, but I don't understand what you mean by "shapes described in the diagonals"? Care to elaborate?
I think he means if you go from top right to bottom left diagonally, in each diagonal column, then it gives a consistent pattern. So first square(1,1) is the “V” shape, then the next diagonal column [square (1,2) and (2,1)] then you have the vertical lines on the right and left making the sides, and then for the 3rd diagonal column [squares (1,3), (2,2), and (3,1)] you have the top horizontal line in common, and then the pattern continues. So the next one you have [squares (2,3) and (3,2) both have the “V” shape, meaning that missing one which is in the next vertical column has to have the 2 vertical lines making the sides. Then you look at the pattern from top left (1,1) and go to the bottom right towards the missing box (3,3) and you see the pattern of the “V” shape, meaning that you have the 2 vertical lines forming the sides and then “V” shape, forming your answer of:
“|V|”
If that makes sense?
Nice. I guessed C because then there would be 2 shapes with 2 lines, 3 with 3 lines and 4 with 4 lines. I thought that made sense but it's always hard to know whether you're right or not
You deserve like 50k subs (for now)
You have chosen the diagonals on your own benefit. just using the diagonals,
In "my" method, I use rows, colimns and diagonals what makes a bit more sense.
If you overlap the figures by rows, columns and main diagonals... you get something similar to XX surrounded by a rectangle.
F makes sense to that.
Have you done the test so you know the answer? or is the answer you think is the correct?
Para mí fue más sencillo, busqué qué forma se repetía exacta de manera simple. Dos líneas, dos x y así, la D era la única que cumplía. Claro que antes miré las diagonales, y la asociación entre las formas, pero la tercera fila me dió la clave.
The answer is C, since it is the only one that matches no pattern in the grid
No clue tell we can use diagonal as clue. But column and row can be. Thats why this puzzle is hard. Are you sure its D?
czcams.com/video/3OCibHRdBbU/video.html
extend the matrix left and right, you will have these diagonal straight lines that repeat a certain shape.
Even though 'D' might be the answer, what if it is actually 'E'? All shapes add up to one composite shape and are the smallest fragments of that composite shape. The next simplest fragment will be 'E'. This presumes less variables than the video and the other comments (providing a better option for the Occam's Razor debate below).
E is the correct answer
@@ageo9886 wait, which one is "more correct" so?
I got E too.
thanks
i did similar method like this, and more, but I got C? Am I that wrong or could it be C too?
i thought it was just building two letters
D could be guessed much sooner there is no indication that surrounded shapes would fit into this model, (d) was always the more reasonable solution. Your method was perfect and is how it is solved nice.
why not E?
What the hell? They TOLD US only to go row-by-row! (I got the answer E by doing it row-by-row)
i managed to narrow it down to BDE, but couldn't identify which of the 3 was the correct answer. sadly i couldn't catch the part where you leapt from BDE to D
Basically, other than the diagonals, the corner square with the 2 opposite squares have a similar shape as well. Overlap both the similar shapes to get D
how do we know that this guy has the correct answer
you wrong lil bro
I love your channel
Much appreciated!
31 mensa is umbeattable :DDD
What the FUCK
Quick talking, could not follow your explanation. Teaching is not for you.
i undeestood perfectly clear , its just a u problem
D
You sound very tired.
he sounds dead inside
Bad & aesthetically ugly puzzle. More elegant would be answer E turned upside down (option not offered)
i also think that. which one is more correct?
I'd say C, but I like to hear other people opinions
