Joetheeskimo Posted March 17, 2005 Share Posted March 17, 2005 Now that I've got your attention (), here's a brain-twister for you guys to figure out. WARNING: Don't try it if you never took 7th grade math. The following is based on a famous problem about Diophantus, a Greek mathematician from the third century. Find how long he lived based on the following facts: One sixth of his life was spent in boyhood. One twelfth of his life was spend as a youth. After 1/7 more of his life passed, he got married. Five years after getting married, he had a son. His son lived 1/2 as long as Diophantus lived. (Don't ask me why ) The son died 4 years before Diophantus died.

Joetheeskimo Posted March 17, 2005 Author Share Posted March 17, 2005 Originally posted by InsaneSith ? Anyway, when do I get my prize? According to your answer... One sixth of his life was spent in boyhood = 14 years of boyhood One twelfth of his life was spend as a youth = 7 years of "youth" After 1/7 more of his life passed, he got married = married at 39 Five years after getting married, he had a son = son at 44 His son lived 1/2 as long as Diophantus lived = son died at 42, which would be when his father was 86...so how could he have died at 84?

El Sitherino Posted March 17, 2005 Share Posted March 17, 2005 no no no. Diophantus is 84. Married at 33. Had a son at 37. Died when he was 84. Link to comment Share on other sites More sharing options...

El Sitherino Posted March 17, 2005 Share Posted March 17, 2005 Still he died at 84. I even checked google (and wikipedia) to make sure I was correct, and I am. Link to comment Share on other sites More sharing options...
Pad Posted March 17, 2005 Share Posted March 17, 2005 I checked it and as master in engineering I can honestly tell you his answer is absolutely correct. x/7 + x/12 + x/7 + 5 + x/2 +4 = x will be the equation (where x equals the total lifetime) and after some work you get 756 = 9x or 84 = x Link to comment Share on other sites More sharing options...

This is why we just need to make it a rule that's written. I'm always right. That way we don't have to prove it each time. Link to comment Share on other sites More sharing options...
