Wierd but extremely hard brainteaser

Postby James » 07 Jul 2013 22:59

I saw this in ye olde internet and decided to share...

Read this passage.

FINISHED FILES ARE THE RE-
SULT OF YEARS OF SCIENTI-
FIC STUDY COMBINED WITH
THE EXPERIENCE OF YEARS.

Now the challenge...
... count how mant letter 'F's there are.

The answer is: (9^2 + 3^3 - 90) / 3.
Did you get them all?

If you didn't, why is this? Why didn't your brain find them all?

This one is pretty old.

There are 6 F's in there. Most people only count 3 because the F's in the word "of" are not counted.
