Question:
Who is the father of M?
Statements:
I - P and Q are brothers.
II - Q's wife is the sister of M's wife.
Analyzing Statement I Sufficiency
Statement I says that P and Q are brothers. This information establishes a familial link between P and Q but provides no details about M or M's parents. Therefore, Statement I alone cannot determine who M's father is.
Analyzing Statement II Sufficiency
Statement II states that Q's wife is the sister of M's wife. This implies that Q and M are related through their wives (likely brothers-in-law, assuming they married sisters). However, this relationship does not provide any information about M's father. Therefore, Statement II alone is insufficient.
Analyzing Both Statements Together
When considering both statements together:
- Statement I: P and Q are brothers.
- Statement II: Q's wife is the sister of M's wife.
Even combining these, we know P and Q are siblings. We also know that Q and M are connected via their wives. This confirms a relationship between Q and M, but it does not reveal anything about M's father or parents. No information links P, Q, or their wives' families to M's paternal side.
Conclusion on Sufficiency
Since neither statement individually nor both statements combined provide enough information to identify M's father, both statements are insufficient.
