Directions: Read the given information carefully and answer the related questions: Eight boxes P, Q, R, S, T, U, V and W are placed one above another in a stack but not in the same order as given. Three boxes are placed between box W and box R. Box T is placed two boxes above box R. Box P is placed just below box T but above box W. Two boxes are placed between box P and box V. Box S is placed three boxes below box V. Box Q is placed adjacent to box W.

Show answer & explanation
Correct answer: E
Concept
In a vertical arrangement, assign consecutive levels from top to bottom and convert every relation into a position difference.
Three boxes between two boxes means a difference of four levels; two boxes above means a difference of two levels; adjacent means a difference of one level. Fix the strongest linked chain first and reject any placement outside the available levels.
Application
Number the levels 1 to 8 from top to bottom.
T is two levels above R and P is immediately below T, so the linked order is T, P, R. Since P is above W and W and R differ by four levels, W must be four levels below R. Taking R at level 3 gives T at 1, P at 2, R at 3, and W at 7. Taking R at level 4 would later put S at level 9, outside the stack, so it is impossible.
Two boxes lie between P and V, so V is at level 5. S is three levels below V, so S is at level 8.
Q is adjacent to W at level 7. Level 8 is occupied by S, so Q is at level 6. The remaining box U occupies level 4.
Cross-check
The final stack satisfies every clue: W and R have three boxes between them; T is two levels above R; P is immediately below T and above W; P and V have two boxes between them; S is three levels below V; and Q is adjacent to W.
Position from top | Box |
|---|---|
1 | T |
2 | P |
3 | R |
4 | U |
5 | V |
6 | Q |
7 | W |
8 | S |
Result
Therefore, box V is placed immediately above box Q.
