One of Mr. X, his wife, their son and Mr. X's mother is an Engineer and another is a Doctor.
1. If the Doctor is a male, then the Engineer is a male.
2. If the Engineer is younger than the Doctor, then the Engineer and the Doctor are not blood relatives.
3. If the Engineer is a female, then she and the Doctor are blood relatives.
Can you tell who is the Doctor and the Engineer?

(In reply to Blood Relative? by Gamer)

A person is a blood relative if they are directly related (not by marriage). Siblings, parents, children, etc, are blood relatives. Spouses and in-laws are not.
