Is the CRT good for predicting intelligence?

it's a good test of what your brain is good at visualizing. question #1 hurts my brain even after knowing the answer, question #2 took a second, question #3 I knew the answer before I finished reading the question.

Because it doubles in size every day. So the last doubling on day 48 fills the lake. Ergo on day 47 the lake is half filled.

What, is it supposed to be 1+2x? This situation is too irrelevant to waste brainpower on it. I can't think of a situation where you're going to speak in riddles about a fucking 1 dollar bat. At least the lilipad thing sounds real but its solution sounds like a sylogism.

Yeah I know now:
A + B = 1.1
A = B + 1

B + 1 + B = 1.1
2B + 1 = 1.1
2B = .1
B = .05

a=lilipad original size
A= lake area
A=a2^48
A/2=1/2a2^48

48=log(2)(A/a)
X=log(2)(A(2a)^-1)

Is this right? Are you telling me somehow the answer to this is 47?

Anon, it doubles each day. If at 48 days the whole lake is covered, the previous day half was covered.
Idk what you did with the log

What good is it to know something as simplistic as that if I won't be able to answer follow up questions such as the amount of lake covered in day x?

How can you find how much is covered on x day if you can't even find the answer to a much simpler question?

You don't need an equation to find the amount on x day, it's a basic doubling exponential that you can count in your head, and you drastically overthought the scenario.

They are easy questions, but they catch people off guard with an "obvious" answer that's wrong. The idea is that smarter people will sense something is wrong with their instinctual response and will dig for the real answer.
