Question: Given the statements: 

 P is the sister of Q. 

 Q is the husband of R. 

 R is the mother of S. 

 T is the husband of P. 

Based on the above information, T is ______ of S. (A) the grandfather (B) an uncle (C) the father (D) a brother | GATE 2022

Solution:

From the given statements:

P is the sister of Q.

Q is the husband of R.

R is the mother of S.

T is the husband of P.

We can deduce the following relationships:

P and Q are siblings.

Q and R are married.

R is the mother of S.

T is the husband of P.

Based on this information, we can conclude that T is the husband of P, and R is the mother of S. However, we don't have any direct information about the relationship between T and S. Therefore, we cannot determine the exact relationship between T and S from the given statements.

Thus, none of the options provided (A) the grandfather, (B) an uncle, (C) the father, or (D) a brother, can be definitively concluded.

But as per Answer Key we can go with the option (D)
