Answer

Going on a trip

Maya, Sharon, Ron, Dan and Ben went out on a hike. The narrow path forced them to walk in single file, one behind the other. Each one of them wore a hat, and carried equipment, food and drink in their backpacks.

At a certain stage they lost their way and a rescue team was dispatched to search for them.

A group of hikers that they passed on the way gave the rescue team the following clues:

• Maya is wearing a green hat.
• Dan has a rope.
• The person wearing the blue hat is eating a salami sandwich.
• Sharon is eating an egg sandwich.
• The person wearing the blue hat is walking behind the person wearing the yellow hat.
• The person with the stick is drinking orange juice.
• The person wearing the white hat is drinking milk.
• The middle person in the line is eating a peanut butter sandwich.
• Ben is last in line.
• The person drinking tea is walking in front of the person who has the matches.
• The person who is drinking milk is walking behind the person with the telephone.
• The person who is drinking water is eating a cheese sandwich.
• Ron is drinking coke.
• Ben is walking behind the person who is wearing the red hat.

And also added:
We are very sorry but we didn't pay attention to two important details:
Who is eating a jelly sandwich, and who has a torch?

The embarrassed rescue team didn't know to recognize the children from the information that they had received and could not manage to complete the missing details.

Can you help them recognize the children and discover who is eating a jelly sandwich and who has a torch?
