Given that Miguel is the grandfather of Raul and Paula is Raul's sister.
Now, let 'x' years be the age of Raul and 'y' years be the age of Raul's sister (Paula).
Also, given is the following information -
Raul's age = Grandfather's age - 60 × sister's age.
Since the age of Miguel, Raul's grandfather is 65 years, so we can write the following equation to find Paula's age
Thus, we can find Paula's age (y) using the equation
where 'x' is the age of Raul.
