Hi everyone,
I've decided after many years of just assuming "I can't do them", to start having a go at logic puzzles. But something I'm really struggling with is these so-called "Unaligned Pair Clues". I CANNOT get my head round them. Here's an example from the tutorials on the site:

The clue here says "Of Laura and the person who got the blue tattoo, one paid $45 and the other chose the Gemini symbol." The tutorial then says that we can deduce that "Laura's tattoo isn't blue". I understand this, because I can read that "Laura" is ONE person, and "the person who got the blue tattoo" is A DIFFERENT PERSON.
What I DON'T understand is where the tutorial says that we can deduce that "The Gemini tattoo didn't cost $45". WHY??? How do we KNOW this?? Here's how the logic goes in my head:
1. Laura is one person
2. The person who got the blue tattoo is another person
3. Laura's tattoo isn't blue
4. We don't know WHICH of the two people above (Laura and the person who got the blue tattoo) paid $45, nor do we know which of the two got the Gemini tattoo.
What am I missing? Could someone PLEASE explain it to me in simple terms, because right now I feel like an idiot!
