Just recieved this in an email. Its a nice puzzle and theres a few ways to work it out but its certainly worth the 5 minutes.
Note: Please don't post the answers
"A man wanted to get into his work building, but he had forgotten his pin-code.
However, he did remember five clues.
These are what those clues were:
§ The fifth number plus the third number equals 14.
§ The fourth number is one more than the second number.
§ The first number is one less than twice the second number.
§ The second number plus the third number equals 10.
§ The sum of all five numbers is 30.
What were the five numbers?
