2. Jordan's sister is either Alex or Charlie.
3. Jordan is either Sam's brother or Sam's only daughter.
Who is the opposite gender from the other three?
1. Charlie's only son is either Sam or Alex.
2. Jordan's sister is either Alex or Charlie.
3. Jordan is either Sam's brother or Sam's only daughter.
Who is the opposite gender from the other three?
Answer
Charlie is the opposite gender.If Jordan is Sam's only daughter, then Jordan cannot have a sister. Therefore, Jordan must be Sam's brother and a male.
If Jordan's sister is Alex, then fact 1 tells us that Sam is Charlie's only son. But since Jordan is Sam's brother, Sam cannot be Charlie's only son. Therefore, Charlie must be Jordan's sister.
Since Sam is Jordan and Charlie's sibling, Alex must be Charlie's son. Now we know that Alex and Jordan are male, while Charlie is female.

Fun. Not too hard , but it would have been easier if I weren't doing it while lying in bed.
I did not try to figure it out. It is late and past my bedtime.

These days its hard to say. I'll check back in a week, maybe someone will have changed their mind.
To be honest. it's a good puzzle!
I got Alex.
because fact 1 said that Charlie's son is either sam or Alex.
And at that moment, when I read " son ", it just reminded me of a father.
so I assumed he is a boy. From there I built up.
Now I know I messed up ... hehe
