Bizzare IQ test question: can anybody explain it?

I recently took an online IQ test and was stumped by this question....

Ralph likes 25 but not 24, he likes 400 but not 300, and he likes 144 but not 145. Which other number does he like?

a) 10

b) 50

c) 124

d) 200

e) 1600

I'm pretty smart, but this question seems like gibberish to me. Not how my mind works, mate.  I know the right answer because I guessed it correctly, but can anyone tell me what the logical associations here are supposed to be?  

For those as stumped as I am by this's an easier one for you

Have you ever taken an online IQ test, and if you have, do you think the results were accurate?

Berengaria, Wanda, I don't think it is a coincidence.
If you know that 144 is a full sqaure, you react at it instinctively. Of course, everyone likes 144, for this very particualr reason. 169 and 196 and 225 and 256 and so on.

I think, likelyhood that a person remembers squares by heart depends on a country: fashions are different, math education is different. And also people with different education come here from different places. Consider also the likelyhood to answer such a question, it also depends on culture.

About the wording:
- such problems: "Vasia eats[likes, kisses, ....] this kind of cookies but doesn't eat that kind of cookies", with characters having math-based habits are familiar to me
- often in math numbers with 'unusual' or noteworthy properties are called 'good'. Informally and formally. It can be even a part of statemnt of a problem or even a serious theorem. "Let's call all Berengarias who satisfy the following condition ........... "good Berengarias". Prove that the number of good Berengarias is even".

P.S. In physics quarks have 'flavours' (which are: up, down, strange, charm, top, bottom). Just another example of application of terms you could find unusual. Point is that, they had to call them somehow:) And a boring 'scientific' word woul only be misleading, becasue they speak of somethign new.

Well, actually I think, measuring body parts is an amazingly silly ocupation. It can be entertaining, but the right thing to be measured in men is penis size then. Girls are multidimensional.

It's a coincidence Berengaria. It's actually pretty easy to figure out if you're into mathematics, especially with the 25 and 144. :)
