Question

Pia's father was 38 years old when she was born. Her mother was 36 years old when her brother, who is four years younger than Pia, was born.
Find the difference between the ages of Pia's parents.

Answer 1

Pia's father's age when she was born = 38

We know that Pia's brother is 4 years younger than Pia.
So, Pia was 4 years old when her brother was born.

Age of her father = 38 + 4 = 42
Age of her mother = 36

Difference between her parents' ages = Age of her father – Age of her mother
i.e., 42 – 36 = 6 years

Pia's father is 6 years older than her mother.
