right,
here's the answer to your second teaser:
Use 6 9's to make 100 using oprations (+ - x /)
[b](9*9)+(9+9)+(9/9) [/b]= 100

try this:
John, Smith, and James are in a competition. Here are their results:
1. The youngest person received the least points.
2. John got half of the points of the eldest.
3. Smith received as many points as both others combined.
Question:
Who is the eldest ? and how can you tell if he is the eldest?

smith is the eldest becoz of number 3.. obviously
but how can smith have the same points as both others combined?
john can be the youngest or the 2nd.. i don't get it..
is this a decimal? or negative?
