Puzzle: Five clerks (Ana, Ben, Cara, Dan and Eli) sit at desks numbered 1 to 5 from left to right. Cara sits at desk 3. Eli sits immediately to the left of Ana. Ben sits somewhere to the left of Dan. Dan does not sit at desk 5. Who sits next to both Dan and Eli?
Correct answer: C. Cara
The only arrangement is: desk 1 Ben, desk 2 Dan, desk 3 Cara, desk 4 Eli, desk 5 Ana. Cara at desk 3 is next to Dan at desk 2 and Eli at desk 4, so she is the only one next to both.
