Answers and Solutions for CAT Data Sufficiency Questions and Answers PDF (Set – 2):
Solutions:
1) Answer (D)
Let the no. of 1,2,5,10 Rs notes be x,y,z,w.
According to given condition we have z+w=x+y+1 .
Now considering statement A
The possible values are 4+3=3+3+1 .
But in this case the data is not sufficient to find price of article as the both 5 and 10 rs can have any of the 4 or 3 notes.
Hence statement A is not sufficient.
Now considering statement B ,
The price of the article was a multiple of Rs. 10.
For this, more than 1 possibility of no. of notes of a particular value is there. Also 2 statements together can’t give the total price of the article.

2) Answer (C)
Using either statement alone, we cannot answer the question.
The factors of 30 are 1, 2, 3, 5, 6, 10, 15 and 30. From the information given in both the statements, the value of m is 15 and n is 2. So, option c).
3) Answer (D)
Even by using both the statements, we do not know whether country X has a higher GDP than country Y because we do not know the absolute values of the GDPs 5 years back. So, the question cannot be answered.
4) Answer (A)
Using statement 2 alone, we cannot determine what the numbers are. But by using statement 1 alone, the only possible values for the two numbers are 6 and 2. So, option a) is the answer.
5) Answer (A)
The question asked is about the number of round trips made in 12 hours. This can be answered if we know the time of travel and the time of waiting. So, the question can be answered by using statement 2 alone but not by using statement 1 alone.
