Hi, guys!

I'm new here.
Can somebody help me with this:

Fill in the missing number:

196 (25) 324

Do you see any logic here?

There are far too many possible ways to 'deduce' the pattern in the first row. Perhaps 25 is the sum of the digits of 196 and 324. Or perhaps 25 is 1 plus the difference between the root of 324 and the root of 196. There are dozens of other logical possibilities. If you force me to guess, I'll say the test-designer wants the answer to be '21' (the sum of the digits), but if I'm right, it's more a proof of my ESP ability than of my mathematical ability-- my only hope here is to guess what the question-designer is thinking. As a logic question, this is completely absurd; there are many different answers that will make perfect logical sense. Certainly not a GMAT question!

its a logic problem that could be from LSAT or some other tests and Ian gave enough logic.

Good logic Ian.

yep, sum of the digits seems to be the natural answer.

That didn't make any sense! I meant to say: 'perhaps 25 is the square of 1 plus the difference between the root of 324 and the root of 196.'
