Solution:

Mr. Bajaj is the Engineer and either his wife or his son is the Doctor.

Mr. Bajaj's wife and mother are not blood relatives. So from 3, if the Engineer is a female, the Doctor is a male. But from 1, if the Doctor is a male, then the Engineer is a male. Thus, there is a contradiction, if the Engineer is a female. Hence, either Mr. Bajaj or his son is the Engineer.

Mr. Bajaj's son is the youngest of all four and is blood relative of each of them. So from 2, Mr. Bajaj's son is not the Engineer. Hence, Mr. Bajaj is the Engineer.

Now from 2, Mr. Bajaj's mother cannot be the Doctor. So the Doctor is either his wife or his son . It is not possible to determine anything further.

My friend and I were recently discussing about the ubiquitousness of technology in our daily lives. Reading this post makes me think back to that debate we had, and just how inseparable from electronics we have all become.


I don't mean this in a bad way, of course! Societal concerns aside... I just hope that as memory gets less expensive, the possibility of transferring our brains onto a digital medium becomes a true reality. It's one of the things I really wish I could experience in my lifetime.
