10 out of 30
 

How many brothers does A have?

II. D is brother of A and is youngest in the family.



A If data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.

B If data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.

C If the data either in statement I alone or in statement II alone are sufficient to answer the question.

D If the data even in both statements I and II together are not sufficient to answer the question.

Even by using both the statements together we cannot determine the gender of B. so A can have one or two brothers.
