Statement − Ram is the only son of Suresh and Mina. Conclusions − I. Suresh and Mina have one son. II. Ram has one sister.

To analyze the given statements and conclusions, we will systematically evaluate each conclusion based on the information provided in the statement.

1. Break Down the Problem

• The statement indicates that Ram is the only son of Suresh and Mina.
• We need to evaluate two conclusions:
  • Conclusion I: Suresh and Mina have one son.
  • Conclusion II: Ram has one sister.

2. Relevant Concepts

• Definitions:
  • "Only son" implies that there are no other sons.
  • The statement does not provide any information about daughters.

3. Analysis and Detail

• Conclusion I: Suresh and Mina have one son.

  • Since Ram is identified as the only son, this conclusion is directly supported by the information in the statement. Therefore, this conclusion is valid.

• Conclusion II: Ram has one sister.

  • The statement provides no information regarding any siblings other than indicating that Ram is the only son. Therefore, it cannot be concluded that Ram has a sister. This conclusion is not valid.

4. Verify and Summarize

• The first conclusion is valid as it aligns with the statement that Ram is the sole son of Suresh and Mina.
• The second conclusion is invalid since there is no mention or implication of Ram having a sister.

Final Answer

• I. Valid (Suresh and Mina have one son).
• II. Invalid (Ram does not necessarily have a sister).
