1. Q.1

   Six friends — A, B, C, D, E and F — live in a 3-floor building (floor 1 at the bottom, floor 3 at the top), with two flats on each floor: Left and Right. A lives on floor 1, in the Left flat. D lives on floor 2, in the Right flat. E lives directly above C (same side, one floor up). F lives in a Right flat. B does not live on floor 2 or floor 3. C does not live in a Right flat. Which flat does C live in?

   Show answer

   Answer: Floor 2, Left

   Solution:

   1. A is on floor 1, Left (given). B does not live on floor 2 or 3, and floor 1’s Left flat is already A’s — so B must take floor 1, Right, the only cell left on floor 1.
   2. D is on floor 2, Right (given).
   3. C does not live in a Right flat, so C must be in a Left flat — on floor 2 or floor 3 (floor 1 is already full).
   4. E lives directly above C. Floor 3 is the top floor, so if C were on floor 3, there would be no floor above for E — impossible. So C must be on floor 2, Left.

   Answer: Floor 3, Right

   Solution:
