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
-
- Only (i)
- Only (ii)
- Either (i) or (ii)
- both (i) and (ii)
- None of these
Correct Option: D
Without knowing the gender of C, we can’t be determined whether B is sister of C or B is brother of C. Similarly without knowing the gender 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.
