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

I.  N earns more than M and P but less than only D.
II. 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.

Answer: Option D

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.
