Data Sufficiency

Q1: Question: Who among P, Q, R, S and T is the lightest? Statements:

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

S is not the heaviest.

A I alone is sufficient while II alone is not sufficient

B II alone is sufficient while I alone is not sufficient

C Either I or II is sufficient

D Neither I nor II is sufficient

E Both I and II are sufficient

ANS:D - Neither I nor II is sufficient

Explanation: From I, we have: R>Q, R>T, S>R i.e. S>R>Q>T or S>R>T>Q. From II, S is not the heaviest. So, P is the heaviest. Thus, we have: P > S > R > Q > T or P > S > R > T > Q. Hence, either T or Q is the lightest.
