Here we have two statements numbered I and II given below. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements.
- If the 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
- If the 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
- If the data either in statement I alone or in statement II alone are sufficient to answer the question
- If the data given in both statements I and II together are not sufficient to answer the question
- If the data in both statements I and II together are necessary to answer the question.
How many sons does D have ?
Statements:
I. A’s father has three children.
II. B is A’s brother and son of D.
A. I alone is sufficient while II alone is not sufficient
B. II alone is sufficient while I alone is not sufficient
C. Either I or II is sufficient
D. Neither I nor II is sufficient
E. Both I and II are sufficient
Answer : D. Neither I nor II is sufficient
Explanation:
From both I and II together, we can conclude that A and B are the children of D but the sex of A and the third child of D is not known. So, both the statements together are also not sufficient to answer the question.
