  • (A) If the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question
  • (B) If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question
  • (C) If the data either in statement I alone or in statement II alone are sufficient to answer the question
  • (D) If the data given in both statements I and II together are not sufficient to answer the question and

Q1:

Question: Among M, N, D, P and K, who earns more than only the least earner among them ? Statements:
  1. N earns more than M and P but less than only D.
  2. M earns more than P who earns less than K.

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: N > M, N > P, D > N. Thus, we have: D > N > M > P or D>N> P>M. But, from II, M earns more than P i.e. D > N > M > P. Also, since P earns less than K and N earns less than only D, so we have: D>N>K>M>P or D>N>M> K > P. Hence, either K or M earns more than only the least earner i.e. P.
