Question: How many children does John have?
- Mary is the only daughter of Regina, who is the wife of John
- Roselin and Maria are sisters of John
- Statement I alone is sufficient but statement II alone is not sufficient to answer the question asked.
- Statement II alone is sufficient but statement I is not sufficient to answer the question asked.
- Both statements I and II together are sufficient to answer the question but neither statement is sufficient alone.
- Each statement alone is sufficient to answer the question.
- Statements I and II are not sufficient to answer the question asked and additional data is needed to answer the statements.
Answer is option (e). Because the statements provided states that John has a daughter and two sisters. John may or may not have a son. So both the statements are not sufficient and we need additional data to answer the question.
