The answer to last week’s challenge is, Q: Sam, Alex, Charlie, and Jordan are related. One of them is the opposite gender from the other three. Here are some facts: 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?

A: 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.

This week’s challenge is:

Q: A man is trapped in a room. The room has only two possible exits: two doors. Through the first door there is a room constructed from magnifying glass. The blazing hot sun instantly fries anything or anyone that enters. Through the second door there is a fire-breathing dragon. How does the man escape?

The answer along with a new challenge, next week.

Have an excellent weekend!
