Ultimate IQ test for those who are interested..

I'm just rethinking here........been a long day

A marble is more dense than water because it sinks (I assume it is made of glass or other dense material.....which is normal). Therefore if the marble is put into the pool the mass of water that it displaces will be less than the mass of the marble.

If the marble is put into the rowboat the amount of water that will be displaced will be equal to the mass of the marble. As the marble has a greater mass than an amount of water that is equal to its volume putting the marble into the boat will cause more water to be displaced than putting it directly into the pool.

So the answer is..........B.

That makes more sense now. It all came down to the relative densities of the water and the marble.

We had a debate yesterday over this question and my answer was B also...

Ok, but I'm also saying that even if the density of the marble was equal to that of water, placing the marble in the boat would cause the water level to rise higher than if the marble was thrown into the water...

If the marble is place in the boat, the boat will not rise with the water and the water will have less surface area to rise...

This is not negligible if the boat takes up a decent portion of the surface area of the water.

It's so obvious it stings. I chose the right answer for a different reason.

Let me just think about that...........

Doesnt it depend upon the shape of the boat..........if it were (and this is unlikely) a hollow cube then the surface area would remain the same. If it were one of those inflatables like a big inner tube with a base added it would depend upon how low in the water the boat already was.

If the boat were empty and an inflatable that was fully inflated I think you would be right.

However no info about the boat is given so you can assume that the shape of the boat is irrelevant IMO.

i told you haters it was b.

thanks for the good explanation, imnotdutch.

No problem bro..........

Plornive........I reckon a lot of people looked past the obvious. Now imagine you are an eskimo with no formal knowledge of displacement and density but an IQ of 200.........you probably would get this wrong. This is why IQ tests are a joke.

This is why IQ tests are a joke.

It seems that any pattern or concept in an IQ test has some adademic analog.

You are probably right.........I'm not sure how you can test somebodies potential in a manner that is totally independent of what they might have or have not learnt.

I got 7 too.

Second question:

What letter comes next?

O, T, T, F, F, S, S, E, __


?

One Two Three Four Five Six Seven Eight

N for Nine

 

[Sundance]

And this one too:

Roentgen : (X rays : Van Allen Belt)) is to ( Bohr : (Hydrogen : Unnilennium )) as ( Oppenheimer : (theory of relativity : atomic bomb)) is to _____ ?

(Planck : (radiation formula : thermonuclear bomb))

(Feynman : ( nanotechnology : radio telescope))

(Rutherford : (atomic structure : theory of gravity))

(Teller : ( quantum foam : hydrogen bomb))

(Curie : (radiation : neutron bomb))

(Einstein : (E=MC2 : cold fusion))

My answer was the last one..any other answers??

why do you think IQ tests dont contain straight up arithemetics? (the candy store one isnt straight up, im talking like mathbook problems). IQ test arent supposed to test things you've picked up in life, they're supposed to test your raw level of intelligence, levels of comprehension, ability to pick up patterns, etc

You're right about that point at the same time

i never understood the point of verbal questions like this..
i mean, shouldnt an accurate IQ test be able to determine the intellectual levels of someone based off of natural intelligence, not something they've learned in life? I mean, a good IQ test should be functional for a rocket scientist, as well as a guy living in a cave away from civilization his entire life..

i don't think talking about raw or natural inteligence thinking about someone who lives in a cave. I am not thinking only in common cultural background that someone needs to have solve some problems, but the way they are exerciced.
It is still valid the point about 2 people, one beeing able to solve only learned exercices and very uneasy with solving different problems and some other person let's say with a higher raw intelligence that's more capable of solving new problems.
Even the person with the higher potential for "raw" intelligence, could only be able to devellop that intelligence to the extend that he could pratice. hardly living in a cave.
