## Task 3 - 020613

Paul tells: "My brother Emil is 3 years older than I am, my sister Lotte is 4 years older than Emil, and my father is three times as old as Lotte. My mother is 5 years younger than my father and turned 40 years old yesterday."

How old is Paul? The answer needs to be justified!
When Paul's mother is 40 years old, his father is consequently 45 years old. Lotte is $\frac{1}{3} \cdot 45=15$ and Emil is therefore 11. Paul is thus 8 years old.
