I found a Very Difficult IQ Test on web.
One of its questions is:

What is the box suggesting?

enter image description here

I have seen the answer but there was no clues for the logic behind that.

  1. 123456789
  2. 176h54308
  3. 627456934
  4. 126485704
  5. 673258719

What is the logic?

The solution is the

first option (123456789)

from the list above.

Disclaimer: I'm not certain this is the complete (or even right) answer.

All little symbols in the perimeter squares (disregard the middle one for now) point to the next square, going counterclockwise. Starting from the upper left, these symbols are the top half (without centre bar) of the digital representations of the digits 1 through 8. The square in the middle is a 9 with the top and bottom quarter missing, as indicated by the 'X'.

None of the other sequences have the correct digital representations to fit the given upper halves: of the symbols in the given sequences, only '1' fits the top left, which provides a starting point to check each sequence.

  • $\begingroup$ what do you mean by "all little symbols point to the next square"? I did not get that. also, if there is such a point to next square, why should we go counter-clockwise? $\endgroup$

    $\begingroup$ With "point to" I mean they are attached to the side you have to cross to get to the next square. Meaning from upper left, you go down, down, right, right, etc, which completes a CCW cycle. I have no idea why the 8 doesn't "point" down though. $\endgroup$ Sep 19, 2014 at 10:23
  • $\begingroup$ i see. but what about the order of numbers? i can see 7 in third position of sequence and 4 should be the 7th character $\endgroup$

I figured adding a picture will more clearly explain the accepted answer. With this image, one can clearly see the 123456789. The parts marked in red are where you were expected to extrapolate.
