Yes, Yes, I know about Puzzling's policy and all that. No, this is not from any ongoing contest. I can't provide a source simply because this was a randomly generated question on a website which I was using.

• But are you really sure it's not? ;) – n_plum May 4 '17 at 15:18
• @n_palum Pretty sure. ;) – Sid May 4 '17 at 15:19
• 69, because you should always go for that if it's one of the options. wink, wink – Marius May 4 '17 at 15:19

I would go with

69

Because

In all a,b and c the numbers opposite to each other add up to the same sum.

Explanation:

A: $29 + 43 = 39 + 33 = 45 + 27 = 72$
B: $29 + 44 = 42 + 31 = 43 + 30 = 73$
C: $59 + 20 = 39 + 40 = ? + 10 = 79$ hence $? = 69$.

Note:

I have no idea what the numbers in the middle of each section mean.

Bonus:

as stated in my comment on the question... You should always go for 69 if you have the option.

• Ah, so the numbers at the centre were all red herrings? I should have figured this out myself instead of troubling all you geniuses. Thank you. – Sid May 4 '17 at 15:27
• @Sid. I added an explanation. – Marius May 4 '17 at 15:28
• Hey, watch it. No need for name calling. Who you calling a genius? – Marius May 4 '17 at 15:35
• Point taken. The next time I see 69, I am going to mark that. If it is wrong, you are to blame. :P – Sid May 4 '17 at 15:36
