# Does this puzzle have a clear solution?

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

• At least you should identify the source of the question. Commented Sep 17, 2015 at 16:48
• I wonder if others would consider this question well-formed. To me it's ambiguous. Commented Sep 17, 2015 at 17:05
• 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. Commented Sep 17, 2015 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.

• I suspect it's B just because that way all the new symbols are different. Commented Sep 17, 2015 at 16:59
• @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.

• Apparently this puzzle considers rotation enough to make a symbol different. Commented Sep 17, 2015 at 17:05
• @Zandar, could be.

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.

• 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. Commented Sep 17, 2015 at 17:02
• @dennisdeems Not in the same proportions. Commented Sep 17, 2015 at 17:03
• @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. Commented Sep 17, 2015 at 22:32
• @moonbutt74 How do you discard option A (as in AE's answer) or option B(as in mine). Commented Sep 18, 2015 at 5:59
