**Reiny**, Friday, September 30, 2011 at 12:10am1. pick a number -- x

2. multiply by 2 -- 2x

3. add 5 -- 2x+5

4. multiply by 50 -- 50(2x+5) = 100x + 250

5. add 1761 -- 100x + 250 + 1761 = 100x + 2011

6. I was born in 1940, so subtract that

100x + 2011 - 1940 = 100x + 71

So whatever you pick for x , would move into the hundreds position of your final answer.

Thus the first number is the choice , the last two numbers are the age.

The rules for step5 would change from year to year, in the next year (2012) we have to add 1762, etc.
