Evaluate if the information in the statements is adequate to answer the question posed.
Question:
How is J related to G?
Statement:
I. G is the son of H.
II. H is the mother of J. J has only one brother.
Show answer & explanation
Correct answer: C
Explanation
To determine how J is related to G:
• From Statement I: G is the son of H (G is male). No information is given about J. Hence, Statement I alone is not sufficient.
• From Statement II: H is the mother of J, and J has only one brother. No information is given about G. Hence, Statement II alone is not sufficient.
• Combining Statements I and II: H is the mother of both G and J, which means G and J are siblings. Since G is the male child of H and J has only one brother (who is G), the relationship of J with respect to G can be determined (J is the sister of G).
Therefore, both Statement 1 and Statement 2 together are sufficient.
