The question below is followed by two statements numbered I and II. Choose the option that describes whether the statements are sufficient to answer the question.
How is Arjun related to Kavya?
I. Arjun and Kavya have the same grandfather.
II. Arjun’s father is the brother of Kavya’s mother.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → The question can be answered by using one of the statements alone, but not by using the other statement alone.
Brothers and sisters share both grandfathers, and cousins share one; so a common grandfather alone does not separate the two.
Statement I alone:
Arjun may be Kavya’s brother or her cousin: not sufficient
Statement II alone:
Arjun’s father is the brother of Kavya’s mother, so he is Kavya’s maternal uncle
The child of one’s uncle is one’s cousin, so Arjun is Kavya’s cousin: sufficient
Statement II alone answers the question, and statement I alone does not.
