The question given below consists of two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the statements and answer the question. There are six persons F, G, H, I, J, and K in a family of three generations. No single person in the family is a parent. How is F related to H? Statement I: G is the brother-in-law of J. I is the only daughter of F. K is the mother of J. Statement II: H is the son of G. K is the mother-in-law of G. J is the brother of
I.

From statement I alone, G is the brother-in-law of J. I is the only daughter of F. K is the mother of J. We get: Case 1: Case 2: So, from statement I alone, we cannot determine the relation between F and H. From statement II alone, H is the son of G. K is the mother-in-law of G. J is the brother of I. We get: So, from statement II alone, we cannot determine the relation between F and H. On combing both the statements together, we get: So, on combing both the statements together, we get F is the grandfather of H. Therefore, data given in both statement I and II together are necessary to answer the question.
