    A is the brother of B. A is the brother of C. To find what is the relation between B and C. What minimum information from the following is necessary? (i) Gender of C          (ii) Gender of B

    A)  Only (i)             

    B)  Only (ii)

    C)  Either (i) or (ii)       

    D)  both (i) and (ii)

    Correct Answer: D

    Solution :

    Without knowing the sex of C, we can't be determined whether B is sister of C or B is brother of C. Similarly without knowing the sex of B we can't be determined whether C is sister of B or C is brother of B. Therefore, both (i) and (ii) are necessary.
