Question

O, P, Q, R, S, T and U are seven boxes that are kept one over the other but not necessarily in the same order. Only one box is kept between R and P. Only one box is kept between S and T. Only one box is kept between P and Q. Q is kept at the lowermost position. T is kept immediately above Q. How many boxes are kept between S and Q?

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

Answer 1

Answer:

C. Two

• Correct Answer: Option C (Two)

• Step-by-Step Solution:

• Given Conditions:

  • Seven boxes: O, P, Q, R, S, T, U

  • Q is at the lowermost (1st) position

  • T is kept immediately above Q → T is at Position 2

  • Only one box is kept between P and Q → P is at Position 3 (since Q=1, T=2, P must be at 3)

  • Only one box is kept between R and P → R is at Position 5 (one box at Position 4 between P and R)

  • Only one box is kept between S and T → S is at Position 4 (one box between T=2 and S=4)

• Final Arrangement (Bottom to Top):

• Position	Box
  7 (Top)	O/U
  6	U/O
  5	R
  4	S
  3	P
  2	T
  1 (Bottom)	Q

• Boxes between S (Position 4) and Q (Position 1):
  → Position 2 (T) and Position 3 (P) = Two boxes

• ∴ The answer is 2 (Option C)

• Related Facts:

  • In linear arrangement/stacking puzzles, always start with the fixed/definite positions first.

  • "Immediately above/below" means no gap between the two items.

  • "Only one box between" means exactly one box separates the two mentioned boxes.
