Sitting around a table are three girls: Annie, Carol and Ellen. Sitting with them are three boys: Bert, David and Felix.

Use the clues to work out where each person is sitting.

Two girls sat next to each other.
David sat opposite Bert.
Felix sat to Carol's left.
Carol did not sit beside Annie or Ellen.
Felix sat opposite Ellen.

I have attached my answer below. Please check it.

Explanation:

As seen on the attachment, 6 people are sitting around a table. This means that the table is "round." The two girls who are sitting beside each other are Anne and Ellen. Carol sat beside Felix and David, which explains why she did not sit beside the two girls. David is on the right of Carol while Felix is on the left. David sat opposite to Bert, who sat beside Anne and Felix. Felix, furthermore, sat opposite to Ellen.
