I am a self-taught man and I'm posting my first question here. I'm facing a challenge I'd like to solve. Based on what I know it fits propositional calculus (hope it is).
Suppose 3 people: a captain, a helmsman, a cook. They all come from different countries: Marocco, Korea, Greece (no specific order). They all have different ages: 35, 42, 25 (no specific order).
I know that: The Moroccan man is not a captain; he is not 25. The Greek helmsman is more than 25.
How old is the captain?
Can you please give me some insight on how to solve it? Thanks for your help
