Who among P, Q, R, S and T is the lightest?

Statements:

1. R is heavier than Q and T but lighter than S.

2. S is not the heaviest.

  • A.1 alone is sufficient while 2 alone is not sufficient
  • B.2 alone is sufficient while 1 alone is not sufficient
  • C.Either 1 or 2 is sufficient
  • D.Neither 1 nor 2 is sufficient

Answer: D

Correct answer: Neither 1 nor 2 is sufficient

Statement 1 puts both Q and T below R without ordering them against each other, so the lightest is one of the two but which is unknown. Statement 2 concerns only the top of the order. Together they still leave Q and T unranked, so the lightest cannot be named.
