A question is followed by two statements numbered (I) and (II). You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and select the most appropriate answer. Question: Five friends, P, Q, R, S and T, are sitting around a circular table facing the centre. Who is sitting second to the left of T? Statements: (I) S sits second to the right of P. T sits to the immediate left of P. (II) Only one person sits between Q and R. P sits to the immediate left of R.
Data in statement I alone is sufficient to answer the question while data in statement II is not.
Data in statements I and II together are not sufficient to answer the question.
Data in statement II alone is sufficient to answer the question while data in statement I is not.
Data in statements I and II together are sufficient to answer the question.
Data in statement I alone is sufficient to answer the question while data in statement II is not.
Statement I directly gives T's position relative to P (T is to immediate left of P), and S's position relative to P (S is second to right of P). Since all face the center, immediate left of P means P is sitting immediate right of T, making P first to left of T and S second to left of T!
Statement I directly gives T's position relative to P (T is to immediate left of P), and S's position relative to P (S is second to right of P). Since all face the center, immediate left of P means P is sitting immediate right of T, making P first to left of T and S second to left of T!
Analyze Statement I
Five friends P, Q, R, S, T are facing the center in a circle. In center-facing circular arrangements, clockwise direction corresponds to the LEFT of a person, and counter-clockwise direction corresponds to the RIGHT of a person. Statement I gives: S sits second to the right of P (S is 2 positions counter-clockwise from P). T sits to the immediate left of P (T is 1 position clockwise from P, which means P is to the immediate right / 1 position counter-clockwise from T). Starting from T going clockwise (to T's left): 1st to left of T is P, and 2nd to left of T is S. Thus, Statement I alone uniquely determines that S is sitting second to the left of T.
Analyze Statement II
Statement II gives: Only one person sits between Q and R, and P sits to the immediate left of R. This statement gives information about P, R, and Q, but contains no information whatsoever about the position of T. Hence, Statement II alone is insufficient to answer who is second to the left of T.
Evaluate Options for Data Sufficiency
Since Statement I alone is sufficient to get a unique answer (S is second to the left of T) while Statement II alone is not sufficient, Option A is the correct answer.
B: Incorrect because Statement I alone is sufficient to answer the question. C: Incorrect because Statement II lacks information about T and is not sufficient, whereas Statement I alone is sufficient. D: Incorrect because combining statements is not required since Statement I alone is already sufficient.
A is correct because Statement I uniquely determines that S is sitting second to the left of T, whereas Statement II gives no information about T.
For facing-center circular arrangements, remember: Clockwise = Left, Counter-Clockwise = Right. Once you establish a relative placement of a person, trace step-by-step along the circle without needing to fix all other unmentioned variables if the specific position asked is already fixed!
