Following are some information about a family consisting of 4 members P, Q, R and S. P is an adult male and has 2 children. Q is the son-in-law of P. R is Q's brother-in- law. There is just one couple in the family. Who is the daughter of P?

Correct option is D

Given Information:

1. P is an adult male and has two children.
2. Q is the son-in-law of P.
3. R is Q's brother-in-law.
4. There is just one couple in the family.

Steps to Solve:

1. Identify the family members and relationships:

   • P is the father since he has two children.
   • Q is P's son-in-law, meaning Q is married to P's daughter.
   • R is Q's brother-in-law, meaning R is either P's son or P's daughter's sibling.
   • There is just one couple in the family, which must be Q and P's daughter.

2. Determine P's children:

   • P has two children: one is a daughter (married to Q), and the other is R (a son, as he is Q's brother-in-law).

3. Answer the question:

   • P's daughter is married to Q.
   • Therefore, the daughter of P is S.

Final Answer:

S is the daughter of P.
