Question
Consider the Question and two Statements given below:Question : Is Z brother of X?Statement-1 : X is a brother of Y and Y is a brother of Z.Statement-2 : X, Y and Z are siblings.Which one of the following is correct in respect of the Question and the Statements?
Solution
Based on the information given:
Statement-1: X is a brother of Y and Y is a brother of Z. This statement does not necessarily mean that Z is a brother of X. Z could be a sister of X.
Statement-2: X, Y and Z are siblings. This statement also does not necessarily mean that Z is a brother of X. Z could be a sister of X.
Therefore, neither Statement-1 nor Statement-2 is sufficient to answer the question "Is Z brother of X?" without additional information about Z's gender.
