Q1: Question: How is M related to N?
Statements:
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:A - I alone is sufficient while II alone is not sufficient Explanation: From I, we conclude that P is the mother of M and N, while Q is the daughter-in-law of P and sister-in-law of N. Thus, Q is M's wife and hence, M is N's brother. From II, we conclude that M and N are the children of S. Also, R is the daughter-in-law of S and sister-in-law of M. So, R is N's wife and thus, N is M's brother. Hence, M is either brother or sister of N. |
