I think all sane people are cachers

Sat Aug 21, 2010 1:02 pm  by tartle

I think all sane people are cachers
and one third of all cachers are sane
but half of all whackos are cachers
with only one whacko that s sane

If eight whackos are cachers
and ninety are attending my ball
how many cachers are neither
sane nor whacko at all?

90 total - 8 wackos = 82 cachers
82- 27 sane (third of 82) = 55
1 of the 8 cacher-wackos is one of these sane folk so - 7 cacher-wackos = 48 plain cachers

Not sure if it means 90 cachers or 90 in total, because 90 cachers would make the numbers better when doing thirds (the answer being 53 instead of 48 1/3)
