Direction (17–21): Read the given information carefully and answer the question. Ten people G, H, I, J, K, L, W, X, Y and Z live in a building with four floors. Each floor has three flats—Flat 1, Flat 2, and Flat 3—from left to right. The ground floor is numbered Floor 1 and the topmost floor is Floor 4. Each flat is built such that Flat 1 of Floor 2 is directly above Flat 1 of Floor 1, and so on. The two flats in which no one lives are on an even-numbered floor and in an even-numbered flat. G does not live on an even-numbered floor and in an even-numbered flat. W lives in the flat just above H. The flat between K and X is vacant, and K lives in one of the flats above X. L lives in an odd-numbered flat which is to the left of X. Z and Y live on the same floor, and no one else lives on that floor. G lives on a floor and in a flat just above W’s floor and flat. I live on one of the floors on which one flat is vacant. Z and I both live in Flat 1. Who is living just above X?

  1. K
  2. G
  3. J
  4. Z
  5. No one

Correct answer: No one

Solution

The clues force a unique floor-flat arrangement. Once Z and Y are placed together on a floor and the vacant flats are fixed on an even floor and even flat, the positions of K, X, W, H, and G become constrained. In the final arrangement, no person is located directly above X.
