Six boxes, C, D, E, F, G and H, are kept one above another. The topmost position is the first and bottom-most position is the last. Three boxes are between D and C, where D is placed at the second last position. Four boxes are kept between C and G. One box is kept between D and E. Box F is above H. How many boxes are between F and D?

  • A.One
  • B.Two
  • C.Three
  • D.Zero

Answer: B

Two boxes lie between F and D. Number the positions 1 to 6 from the top. D is second last, so D is 5. Three boxes are between D and C, so C is 1. Four boxes are between C and G, so G is 6. One box is between D and E, so E is 3. The remaining positions 2 and 4 go to F and H, and F is above H, so F is 2 and H is 4.

Between F (2) and D (5) are positions 3 and 4, so two boxes. One and three miscount that gap, and zero would need F and D to be adjacent.
