here is the second Math problem for 6 year olds that can be a bit tricky..but asian mathematicians who designed this said it will be good to increase their ability to do math...
So if you can get this, i'd be impressed :o.

Every time a Gamefaqs User PROVES they Stepped on a Bug, i will STOP Posting for 24 Hours...Beware, this is NOT a good thing to do!!
this is the first one of these "problem for kids is really hard!!" problems I've actually been able to solve easily
circle is 9kg, so square is (72 - 45) = 27kg, so 2 squares are 54kg

Need some info on the distances of things from the fulcrum

It would appear, if we define one unit as the diameter of a ball, that the lever is basically three units wide. Although it's not quite accurate, I think we have to assume that in the first example, the balls' centers of masses are 1.5 and 2.5 units out, and the weight ranges from 1 to 3 units out, so it's COM it's 2 units from the fulcrum.

If you listed 27 (and numbers in that range) as an answer I'm sure it could have fooled at least 25% of the correct responses.

Remember though, this is a problem for "6 year olds," and I don't remember being taught about torque in the first grade. (Not that my experience is anything to go by.)
If you make that assumption, this is actually quite simple.

FFS, only post these things if they're actually tricky.

Most people forget their torque lesson, it's one of the first things that gets covered in first grade.
