Post #701=79

 

Why not 68? 

I understand why it *could* be 79 (7 in "ten's", 7+1+1=9 in "ones"), but I think it could also be 68 - each number on the left goes up by 1 where each number on the right goes up by 11. 

 

I wonder if this puzzle was designed to cause conflict by having 2 equally valid answers and making/letting the subject think there is only one. 2 subjects get different answers and duke it out...

 

It is also possible that only 20% of the people doing the puzzle will give BOTH answers.

 

Is there a reason it is not 68 for the reason I gave?

No, the '=' is more of a relationship like an analogy in this sense. You could read it as "115 is to 57 as 117 is to what?"

 

Edit: Mathematics is so great that I might be speaking entirely out of my ass at this point. Fallacy rules.

Actually, was directed to nikongod. But yes, there is also the increase by 11 pattern though I was thinking along the lines of the 7 and 7+1+1 (79) = 117.

It's a trick question.  It establishes a linear pattern early, then skips a step at the last.  The stupid thing is, it tells you it's going to do that.  It's telling you, whatever your first inclination is, it's probably wrong.  Double-think your answers (which most of us are taught not to do).
