      Solution

      From statement I alone, 'F @ I $ G % J, D @ J' From the above information, we make the following family tree: From statement I alone, ‘E % C * G * K, I * H, I $ G % J’, we get From the above information, we make the following family tree: So, from statement II alone, we cannot answer the above question. So, data given in statement II alone is not sufficient to answer the question. From statements I and II together, we make the following family tree: So, from statements I and II together, we cannot answer the above question. From statement I and III together, we make the following family tree: So, from statements I and III together, we get J is the brother-in-law of H's son. So, data given in statements I and III together is sufficient to answer the question. From statements II and III together, we make the following family tree:   So, from statement II and III together, we get J is the brother-in-law of H's son. So, data given in statements II and III together is sufficient to answer the question. Therefore, the data in both the statements I and III together are necessary to answer the question.
