Question: How is T related to K?

Statements:

  1. R's sister J has married Ts brother L, who is the only son of his parents.
  2. K is the only daughter of L and J.

[A]. I alone is sufficient while II alone is not sufficient
[B]. II alone is sufficient while I alone is not sufficient
[C]. Either I or II is sufficient
[D]. Neither I nor II is sufficient
[E]. Both I and II are sufficient

Answer: Option E

Explanation:

From I, we know that L is T's brother and J's husband. Since L is the only son of his parents, T is L's sister.

From II, we know that K is L's daughter.

Thus, from I and II, we conclude that T is the sister of K's father i.e. T is K's aunt.

How to know the gender of T. Guy or girl. Uncle or aunt?

It was clearly mentioned that L is the only son, hence T must be a girl that is his sister.
