Try to figure out the answers from the 2 patterns below. Find all the 10 digits first. Rotate if necessary.

enter image description here

A: What is the missing number? [?] [10] [11] [9] [11]

enter image description here

B- What is the missing number? [?] [ 3] [ 7] [ 2] [ 6]

    $\begingroup$ Can you post smaller images, or one containing both? It's very hard to compare them as I have to scroll up and down. $\endgroup$ – Mordechai May 10 '17 at 18:54

    $\begingroup$ @Mordechai done. You can just put 'm' for medium at the end of the imgur code $\endgroup$ – Beastly Gerbil May 10 '17 at 20:01

Partial solution:

The images can be divided such that line segments can be grouped to represent a (possibly rotated) number that would appear on a digital clock. Each line segment must be used once.

The image also contains at least one of each numeric digit.
Then, you group adjacent numbers together and take their sums. Reading the sums clockwise will get you the sequence in the proper order.
image A
We have [?], 10 (1+9), 11 (8+3), 9 (2+7), 11 (6+5).
So the unknown must be 4+0 = 4.

B: In progress. My strategy may be wrong because I can't find a solution. There are 4 locations that could be the "0", and all of them result in line segments that aren't numeric.

  • $\begingroup$ That's actually B- $\endgroup$ – TSLF May 12 '17 at 17:56
  • $\begingroup$ @TSLF I figured that was a typo because the negative sign is not a digit. $\endgroup$ – MikeQ May 12 '17 at 21:51
  • $\begingroup$ @ Mike @But that's how else can 2 digits stick with each other in 2 layers $\endgroup$ – TSLF May 13 '17 at 14:00
