Prelims 2026 · CSAT / Logical Reasoning · Question 33

P, Q, R, S and T are ranked 1 to 5 (not necessarily in that order). The rank of P is 4, the rank of Q is not 5, the rank of R is 1, the rank of S is not 2, the rank of T is not 3. Then which of the following is/are correct?<br/>I. If the rank of S is 3, then that of T is 2.<br/>II. If the rank of Q is 3, then that of T is 5.<br/><br/>Select the answer using the code given below.<br/>

  1. I only
  2. II only
  3. Both I and II
  4. Neither I nor II

Answer

Neither I nor II

Ranks fixed: R=1, P=4. Remaining ranks {2,3,5} go to Q,S,T with Q≠5, S≠2, T≠3. If S=3, then Q=2 and T=5, so I is false. If Q=3, then S=5 and T=2, so II is false. Hence neither I nor II.
