Six persons — P, Q, R, S, T and U — attend a function on different days of a week starting from Monday to Saturday, but not necessarily in the same order. Who among the following attends the function on Thursday? Statement I: P attends the function three days after U, who is not the first person to attend the function. One person attends the function between T and R. T attends the function three days after Q. Statement II: Two persons attend the function between S and R, who attends immediately after P. Three persons attend the function between P and Q. S attends the function before T. Statement III: U attends the function two days before T, who attends immediately after P. One person attends the function between Q and S.

  1. Statement I alone is sufficient to answer the question whereas both statements II and III are not sufficient to answer the question
  2. Statement II alone is sufficient to answer the question whereas both statements I and III are not sufficient to answer the question
  3. Statement III alone is sufficient to answer the question whereas both statements I and II are not sufficient to answer the question
  4. Any two of the given statements are necessary to answer the question

Correct answer: Statement III alone is sufficient to answer the question whereas both statements I and II are not sufficient to answer the question

Solution

Statement III alone gives a chain of positions: U is two days before T, T is immediately after P, and Q and S are separated by one day. This is sufficient to determine the arrangement uniquely and identify Thursday. Statements I and II do not uniquely fix the day of Thursday on their own.
