Dear Drools Developers,<br><br>best wishes for a successful New Year 2012. As it is a leap year, you&#39;ll have an extra day for pushing Drools ahead ;-)<br><br>While you are waiting for the bubbly to pop open you might pass the time by solving (I suppose you&#39;ll use Drools) the following little problem:<br>
<br>Five friends (Bess, Ida, Hilda, Tony, Walt) live next to each other on a small road. The numbers of their houses are 1, 3, 5, 7 and 9. They are 40, 42, 44, 48 and 50 years old. Each of them has a hobby - but no two have the same. The hobbies are: paragliding, biking, volleyball, hiking und handball.<br>
<br>The Person living at house no. 3 is 4 years younger than Hilda.<br>Tony who is older than Walt lives in house no. 9.<br>Walt likes biking.<br>The woman who likes paragliding is 44 years old.<br>The person living at no. 5 likes to play a ball sport.<br>
The 48-year-old person enjoys hiking.<br>The house number of the person who likes to play handball, is higher by 4 than the house number of the 40-year-old person.<br>Ida is not the youngest woman.<br><br>Who lives between Bess and the 42-year-old person?<br>
How old is Tony?<br>What is the number of Walt&#39;s house?<br>Who is 40 years old?<br>What is the number of the house of the 48-year-old person?<br>What is Hilda&#39;s hobby?<br><br>
