Who is older, Amit or Naveen?
Statement I: Naveen was born in the year 1990 and is 5 yr younger than Amit's brother.
Statement II: Amit is twice as old as his brother.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → If statements I and II together are needed to answer the question
The question can be answered only if the statements link Amit with Naveen. Amit’s brother is the link between them.
Statement I alone — not sufficient. It gives Naveen’s year of birth and says he is 5 years younger than Amit’s brother, but it says nothing about Amit himself.
Statement II alone — not sufficient. Amit is twice as old as his brother, so Amit is older than his brother, but Naveen is not mentioned.
Both together — sufficient. Amit is older than his brother (II), and his brother is older than Naveen (I), so Amit is older than Naveen.
