(a) Statement 1 alone is sufficient to answer the question (b) Statement 2 alone is sufficient to answer the question (c) Both Statement 1 and Statement 2 are sufficient to answer the question
(d) Both Statement 1 and Statement 2 are not sufficient to answer the question
Ans. (d)
EXP. From Statement 1 X is the brother of Y, and Y is the brother of Z. But we do not know whether Z is a male or a female. So, we cannot say whether Z is the brother or sister of X.
From Statement 2 X, Y, and Z are siblings. It tells us
nothing much. Here, also the gender of Z is not known. So,
Z can be either brother or sister of X. Even if we combine the two statements, we cannot answer the given questions.
Therefore, Statement 1 and Statement 2 are not sufficient to answer the question.
