Question from an IQ test

[Scruit]

You want a TRUE IQ test, go to Mensa. I still have the 97 yearbook, the year I joined. :D

I don't think there is a "correct" answer for this type of quesiton though. Rather it see in what way would you solve it, or what pattern do you see. Otherwise I'd just use my calculus grade (which is not all that high lol, hate math) as my IQ.

Ill just use my waist size because that seems to be growing rather quickly.

Unfortunately there is not a square root symbol here on the keyboard, but take a look at this picture: http://mathworld.wolfram.com/s3img368.gif

A square root of x is a number r such that r to the second power = x. Square roots are also called radicals or surds. Any positive real number has two square roots: one positive and one negative. For example, the square roots of 9 are 3 and -3. Any nonnegative real number x has a unique nonnegative square root r; this is called the principal square root. For example, the principal square root of 9 is 3, while the other square root of -9 is -3. In common usage, unless otherwise specified, "the" square root is generally taken to mean the principal square root. T

Any nonzero complex number z has two square roots. For example, using the imaginary unit i, the two square roots of -9 are +/- 3i. The principal square root of a number z is returned by the Mathematica command Sqrt[x].

The square root of 2 is the irrational number, which has the simple periodic continued fraction 1, 2, 2, 2, 2, 2, .... The square root of 3 is the irrational number, which has the simple periodic continued fraction 1, 1, 2, 1, 2, 1, 2, .... In general, the continued fractions of the square roots of all positive integers are periodic.

So, for the question above, he likes even, or rational, numbers.

The sqaure root of 400 = 20 - he likes
The square root of 300 = 17.32 he dislikes
The square root of 100 = 10 - he likes
The square root of 99 = 9.95 - he dislikes
The square root of 2500 = 50 - he likes
The square root of 2400 = 48.99 - he dislikes

Figure the square roots of the choices and you will discover the answer.

:confused: I'd rather just guess!

Who said so, it's ^(0.5). :p
