Just wondering whether anyone can see an unambiguous solution the reasoning test example below? Please explain your reasoning if possible. Thanks.

  • $\begingroup$ At least you should identify the source of the question. $\endgroup$ – dennisdeems Sep 17 '15 at 16:48

    $\begingroup$ I wonder if others would consider this question well-formed. To me it's ambiguous. $\endgroup$ – dennisdeems Sep 17 '15 at 17:05
  • $\begingroup$ The movement of the puzzle is dictated by the right column of each set, the right column from A becomes left column of B flipped with enlarged character. The spacing of the arrow [top-right] of block E makes B in the answer selection set the winner. $\endgroup$ – moonbutt74 Sep 17 '15 at 22:24

The answer is either A or B...

In each move:

  • bottom right shaded symbol becomes top left hollow symbol

  • top right symbol is rotated and enlarged to become bottom left symbol

I can't see any means of deciding between A and B - the horizontal alignment of the left column maybe? - so I'm going to go with no, I don't think there is a unique solution.

Or if a feeble reason will do, then

  • new symbol in top right must contain a vertical line

And then the answer is uniquely A.

    $\begingroup$ I suspect it's B just because that way all the new symbols are different. $\endgroup$ – Zandar Sep 17 '15 at 16:59

    $\begingroup$ @Zandar It doesn't have to be new though, top-right in example 4 is the same as top right in example 2, just rotated. $\endgroup$ – A E Sep 17 '15 at 17:03
  • $\begingroup$ Apparently this puzzle considers rotation enough to make a symbol different. $\endgroup$ – Zandar Sep 17 '15 at 17:05
  • $\begingroup$ @Zandar, could be. $\endgroup$ – A E Sep 17 '15 at 17:05

It actually does make sense when you see the hint.

If a diagram is of the form

\begin{matrix} L & ᴎ \\ M & ⚫ \\ \end{matrix}

Then the next is of the form

\begin{matrix} \circ & P \\ \text{N} & Q \\ \end{matrix}

Here $\circ$ was filled black in the first matrix and filled empty in the second and ᴎ was flipped vertically and enlarged. P and Q are new unused figures.

Hence the answer should be B. A doesn't work because the hollow arrow was used before. The diamond was used before too, but it was of different proportions. Look at the hint, it actually reveals the whole answer.

I could answer this quickly only because I saw the hint. I don't know how much time it would take me if I didn't (or if I could even solve it for that matter)

Is the problem clear enough?

It seems that A E has come up with a equally valid reasoning for A. In my opinion, the puzzle is unambiguous enough to discard options C,D,E. But differentiating between A and B is up to interpretation.

    $\begingroup$ Why can't it be $A$? $\endgroup$ – GentlePurpleRain Sep 17 '15 at 16:58

    $\begingroup$ I think "new" is ambiguous; it could refer to the current iteration rather than the whole series. There has already been an arrow, but there has also already been a diamond. But this is likely the intended answer. $\endgroup$ – dennisdeems Sep 17 '15 at 17:02

    $\begingroup$ @dennisdeems Not in the same proportions. $\endgroup$ – Zandar Sep 17 '15 at 17:03

    $\begingroup$ @moonbutt74 There is nothing in question to clarify that. There is nothing that suggests mine either, but it is a pattern puzzle which means you are supposed to figure these out by yourselves. Often this means these puzzles are open to interpretation which is the case here. $\endgroup$ – Rohcana Sep 17 '15 at 22:32

    $\begingroup$ @moonbutt74 How do you discard option A (as in AE's answer) or option B(as in mine). $\endgroup$ – Rohcana Sep 18 '15 at 5:59
