• (B) If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question
• (C) If the data either in statement I alone or in statement II alone are sufficient to answer the question

Question: In which year was Rahul born ?

Statements:

1. Rahul at present is 25 years younger to his mother.
2. Rahul's brother, who was born in 1964, is 35 years younger to his mother.

I alone is sufficient while II alone is not sufficient
II alone is sufficient while I alone is not sufficient
Either I or II is sufficient
Neither I nor II is sufficient
Both I and II are sufficient
Explanation:

From both I and II, we find that Rahul is (35 - 25) = 10 years older than his brother, who was born in 1964. So, Rahul was born in 1954.

He didn't mention the brother is younger or older so insufficient data.

How come he be 25 yaers old if he is born in 1954 he might have been born in 1974?

We don't consider the answer but judge whether the statements are sufficient or not.

Gouthami said:   10 years ago
In this the answer is not important to find the year we use single conclusion or double statement is important and above problem clearly understood that Rahul 10 years elder to his brother so to conclude both statements are necessary to answer the question.

Suppose Rahul's mother age is 50.

So Rahul is 25.

And his brother is 15.

So brother was in born 1964.

So Rahul is older than brother.

That's why his birth age is less than brother.

Rahul is elder to his Brother and He was born in 1954. And In statement no where Rahul age is mentioned. The answer i.e E, that we need both the statement to answer this question.

It should be 1954 Rahul is elder son to his mother, when his brother is born in 1964 so obviously he should born earlier i.e. 1954.
