Daily Practice Questions Questions for CAT with Answers PDF

From statement I alone, we can see that Amit has two sisters and Amit is the one common brother of those sisters. But no information about the other people is given which would make the number of members less than 5. So, I alone isn't sufficient
From II alone, we can figure out that 'two mothers and two fathers' means 4 members.
But no information about other people is given to make member not less than 5 in number. Thus, II alone isn't sufficient.
From I and II together, we can see Amit has two sisters, a mother, a father, a grandmother and a grandfather, so total of 7 people, which validates the question statement.
Thus, both statements are needed to answer the question.

From I alone, we can see that brother's wife's only son is nephew and grandmother of nephew is mother.
So, B is the mother of A. Thus, statement I alone is sufficient.

From II alone, we can see that brother's wife's father-in-law is father.
So, B is the mother of A. Thus, statement II alone is sufficient.

So, either I or II alone is sufficient.

om I alone, we can find the shortest distance as follows:
Shortest distance:

From II alone, we cannot find the shortest distance since it only mentions speed, and no distance is mentioned.
Thus, I alone Is sufficient to answer the question.

From I alone, we can figure out the position of every person.

Thus, statement I alone is sufficient and S is sitting to the immediate left of P.
From statement II alone, we cannot figure out the position of everyone as R could be either to the immediate left or right of P.
Thus, II alone is not sufficient.


Thus, statement I alone is sufficient to answer the question.

Using both the statements, we get the arrangement as:


E is sitting to the immediate left of A.
Hence, the question can be answered by using both the statements together.

From I alone, we can figure out the distance between his home and office. But we don't know the time he took to come back, so I alone isn't sufficient.
Distance between his home and office = 
So, 13 km is the distance.
From II alone, we can figure out that Amit took 40 minutes to come back home. But since distance isn't given, we cannot find the speed. Thus, II alone isn't sufficient.
From I and II together, we get the distance to be 13 km, and the time to come back to be 40 minutes. So, the speed is 19.5 km/hr.
Thus, I and II together are sufficient to answer the question.

From I alone, we can see find the positions of A, B and C. But no mention of position of D is there, so I alone is not sufficient.
From II alone, we can figure out the position of each of the four people as follows:



So, B is to the north of D.
Thus, only statement II is sufficient to answer the question.

From I alone, we get that A lives on the floor above C, and B lives on the floor above D. Thus, we can have many different arrangements.

Thus, I alone isn't sufficient.
From II alone, we only get that C lives on the floor below the top floor, but no information about the person on the top floor is obtained.
Thus, II alone is not sufficient to answer the question.
From I and II, we get that since C lives on floor below the top floor, therefore only one arrangement is possible under this condition.

A
C
B
D
Thus, A lives on the top floor.
Hence, both statements together are needed to solve the question.

From I alone, we can see that there is no mention of when the exam would take place. Thus, I alone is not sufficient to answer the question.
From II alone, we can see that since Gaurav has an exam every 3^rd day and his last exam was on Monday, his next exam would be on Thursday. But no information about the date is provided, so II alone is not sufficient.
From I and II together, we cannot figure out the date of the exam as no information about it is provided.
Thus, both statements I and II are not sufficient to answer the question.

From I alone, we can figure out that A is the son of P's daughter's only brother . So, A is the grandson of P. But no reference to J is there, so I alone is not sufficient.
From II alone, we can see that P is the grandfather of J. But no reference to A is there, so II alone is not sufficient.I and II together tell that A is the brother of J.

Thus, statements I and II together are sufficient to answer the question.
