Question from Nyra, a parent: Christmas 2004 was over and three teenagers were looking forward to their birthdays. Eric's was in February and Lisa's and Tammy's in January. Tammy is 8 weeks older than Eric, but 3 days younger than Lisa. What year were the girls born in? |
Nyra,
The clues are
- They are teenagers in 2004 (13, 14, 15, 16, 17, 18 or 19),
- Eric was born on February 29 (the only way to make the age difference work with birthdays in January and February).
