A real brainteaser... (for you vid)

My daughter is twice as old as my son and half as old as I am. In twenty-two years my son will be half my age. How old is my daughter?

22

d= daughter
s= son
f= father

d= 2s

f= 2d

(f+22)/2 = s+22     OR       s= ((f+22)/2)-22


so. . .

s= (2d+22)/2)-22

and then. . .

d= 2(2d+22)/2)-22) = 22

It\'s an oldie, but no one got it but me.  Let\'s see if anyone has gotten wiser since last time.

A girl was eight years old on her first birthday. How could that be?

Well, if she was born on February 29, 1896 for example, the next time February 29th would occur would be 1904, or 8 years later.

Leap year happens every four years, EXCEPT "century years should only be leap-years if they were divisible by 400."

Since the year 1900 is not divisible by 400, then it\'s not a leap year.

Why the 400 year exception?  The earth revolves around the sun in 365.24219 days.  This was originally rounded off to 365.25, and every four years we have an extra day.  By using the 400 rule, we get the more accurate  365.2425 days.  Even though, this is still off.  In the year 10,000 AD, we will be 3 days off due to this rounding.  (Assuming we\'re still here, and we\'re still using the Gregorian calendar.)
