Question

A, B, C and D live in a building which has 14 floors. A lives two floors above B. C lives on the 14th floor immediately above A. D neither lives immediately above nor immediately below B. The first 7 floors of the building are vacant. On which of the following floors does D live?

• A. 8th
• B. 10th
• C. 12th
• D. 9th
• E. Cannot be determined

Answer 1

The correct option is E

Cannot be determined

Given that the first 7 floors of the building are vacant.

$\begin{array}{cc}{14}^{th}& C\\ {13}^{th}& A\\ {12}^{th}& \\ {11}^{th}& B\\ {10}^{th}& \\ 9^{th}& D\\ 8^{th}& D\\ 1to{7}^{th}& Vacant\end{array}$

Also given that D neither lives immediately above nor immediately below B. So D does not live in 10th or 12th floor but for 9th and 8th floor it is not clear that in which one he lives. So the answer cannot be determined.
