Who is to the immediate right of P among five persons P, Q, R, S and T facing North?

Statements:

I. R is third to the left of Q and P is second to the right of R.

II. Q is to the immediate left of T who is second to the right of P.

  1. A.

    The data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question

  2. B.

    The data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question

  3. C.

    If the data in either statement I alone or statement II alone is sufficient to answer the question

  4. D.

    If the data in both the statements I and II together is not sufficient to answer the question

Show answer & explanation

Correct answer: C

Concept: In a Data Sufficiency seating question, a statement is individually sufficient once its own clues fix the specific relationship asked about -- here, who sits immediately to the right of P -- even if other seats stay undetermined. Test each statement fully on its own before considering whether they must be combined.

Statement I alone:

  1. R is third to the left of Q, so Q's position is exactly three seats to the right of R's position, in every valid arrangement.

  2. P is second to the right of R, so P's position is exactly two seats to the right of R's position.

  3. Subtracting, Q's position is exactly one seat to the right of P's position -- this holds for every seat R could occupy, so Statement I alone already fixes who sits immediately right of P.

Statement II alone:

  1. T is second to the right of P, so T's position is exactly two seats to the right of P's position.

  2. Q is immediately to the left of T, so Q's position is exactly one seat to the left of T's position.

  3. Combining the two, Q's position is exactly one seat to the right of P's position -- fixed directly from Statement II's own two clues, without needing R's, S's, or T's exact seat number.

Cross-check: Both statements are built from different reference points (one from R, one from T) yet converge on the identical relative gap between P and Q, confirming the derivation is consistent. Since each statement independently answers the question asked, the data in either statement alone is sufficient to answer the question.
