Direction: Each of the following problems consist of a question followed by two statements, I and II. You must determine whether the information given by the statements is sufficient to answer the question asked. In addition to the information provided in the statements, you should rely on your knowledge of mathematics and ordinary facts (such as the number of seconds in a minute).
Is Babu older than Raghu?
I. The ratio of Raghu’s age to Babu’s age is 7 : 4.
II. In 6 years Raghu will be half as old as he is now.
- A.
if the question can be answered by using only statement I
- B.
if the question can be answered by using only statement II.
- C.
if the question can be answered by using both statements together, but cannot be answered using either statement alone.
- D.
if the question cannot be answered even by using both statements together.

Show answer & explanation
Correct answer: A
Answer: a
If you think that both statements are necessary to answer this question, you fell into the trap. Read the question clearly. It only requires us to determine who is older but not asked us to find their ages. If the ratio of the their ages is 7 : 4, then Raghu, the 7 part, is older than Babu, the 4 part. So we can clearly state that Babu is not older than Raghu. It makes no difference that the answer to the question is No. A ‘no’ is as good as a ‘yes’.
Statement II alone is not sufficient. You can use it to find out how old Raghu is now, but you have no information about his age relative to Babu’s age.
So option a is correct.
