Eight boxes P,Q,R,S,T,U,V,W stacked one above the other. Which box is just below U? Statement I: >3 boxes between S and T (T below S). Q and S adjacent. 2 boxes between U and Q. 1 box between P and T. Statement II: 1 box between Q and R. 2 boxes between P and Q. 1 box between T and R. P not adjacent to T. U exactly between P and box just above R.

1. If the data in statement I alone are sufficient
2. If the data in statement II alone are sufficient
3. If the data either in statement I alone or statement II alone are sufficient to answer
4. If the data in both the statements I and II together are necessary to answer

Correct answer: If the data in both the statements I and II together are necessary to answer

Solution

Statement I alone: Constraints on S,T,Q,U,P leave multiple valid arrangements — cannot uniquely identify box below U. Statement II alone: Q,R,P,T positions constrained but U's exact position (between P and box above R) still leaves ambiguity without combining with I's constraints. Both I and II together uniquely fix the arrangement and identify the box below U.
