Question

How is T related to K?
Statements:
1. K has two sons; one of the sons is A.
2. The mother of T has only two sons - Aand B.

• 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 1

The correct option is E Both I and II are sufficient

From II, we know that T's mother has only two sons, A and B. This implies that T is the sister of both A and B.
But, from I, A is also K's son. So, T is the daughter of K.
