Bad thing for a moderator to say, perhaps, but I think this puzzle is worth looking at,

even if it may have been posted before. So if you happen to know the answer from

a previous posting, let it ride for a few days. :unsure:

 

There are three pairs of balls - red, white, and blue.

In each pair one ball is a little bit heavier than another one.

All the heavy balls weigh the same, and all the light balls weigh the same.

Also you have a balance scale with exactly three outcomes: <, = and >.

 

You need to identify the three heavy balls.

How many times do you need to use the scale?

Women are definitely stronger. We are [Fe]males, after all...

Some of what makes me me is real, some of what makes me me is imaginary...I guess I'm just complex. ;P
