Data Sufficiency - CAT 2013
Question 4 the day:
May 10, 2002
The question for the day is a data sufficiency question. And for a change there are no numbers in this question.
In this question, there is a question statement which is followed by two statements. You have to decide whether the information provided in the two statements is sufficient for answering the question.
- Mark 1
- If the question can be answered by using one of the statements alone, but cannot be answered by using the other statement alone.
- Mark 2
- If the question can be answered by using either statement alone.
- Mark 3
- If the question can be answered by using both statements together, but cannot be answered by using either statement alone.
- Mark 4
- If the question cannot be answered even by using both the statements together.
- Question
- Mohan drinks whisky whenever he is upset. Is he upset now?
(A) When Mohan drinks coffee he is not upset.
(B) Mohan is drinking whisky now.
Correct Answer - (4)
Solution
The question states that Mohan drinks whisky whenever he is upset. There is a small trick in this statement. Do not misinterpret this statement to mean that Mohan drinks whisky only when he is upset. He drinks whisky when he is upset and could be drinking whisky at other times too.
Statement A mentions that when Mohan drinks coffee he is not upset. That does not mean that he will be upset whenever he does not drink coffee. So Statement A alone does not provide sufficient data to answer to this question.
Statement B mentions that Mohan is drinking whisky now. It does not necessarily mean that he is upset now. Hence the data in statement B is not sufficient to answer the question.
Statement A and B together also do not provide any additional information to answer the question. Hence, the data provided in both the statements is not sufficient to answer the question.
