Answer: Q is currently in Office C, R and T are currently in Office D. Answer: C.
- Fix T's current room: T will move to the Big Office (garden side). So T is currently NOT in the Big Office. R currently shares with T, so R and T are together in one of: A, B, C, or D. The WI is not an office, so they must be in A, B, C, or D.
- Place P and Q together: P and Q must share an office. The five employees need to fit into available offices. If R and T are in Office D (entrance side, right), then P and Q must be in another office. Office C (entrance side, left) is separate from the WI and from D.
- Check adjacency for S: R wants to move to the office adjacent to S (the intern). If R and T are in Office D, the adjacent offices to D are Office B (above) and the WI (beside). S could be in Office B. P and Q are in Office C. That places all five: S in B, P+Q in C, R+T in D. This satisfies all constraints.
- Read off the answer: Current locations: P and Q are in Office C, R and T are in Office D, S is in Office B. So Q is in Office C, R is in Office D, T is in Office D.
