Suppose a question has two statements labeled I & II. Using these given 2 statements you will have to find out that whether:

• Whether answer can be obtained from Statement I alone, but statement II alone is not sufficient to mark the answer.
• Whether the answer can be obtained from both statements I and II together, but neither of the statement alone is sufficient to answer the question
• Whether the answer can be obtained from statement II alone but statement I alone is not sufficient to answer the question
• Whether We can answer the asked question from either statement I or statement II.
• Last but not the least, whether we can not answer the question asked from Statement I and II together, and if any additional information is required to answer the question.

In Data Sufficiency the given information is considered sufficient only when it is possible to determine one numerical value as the answer to the question.

Data Sufficiency Tips

As by now aspirants must have a clear understanding of the data sufficiency concept, here are few tips and tricks as how you can easily solve such type of problems.

Try and Focus on the Question

While answering data sufficiency questions focusing on the question is important as then you will be able to figure out that whether the given statements are sufficient enough to answer the question asked or not.

Consider each statement Individually

Consider the statements individually without in reference to each other. First check the first statement individually that whether it provides enough information, if not then look at the second statement. If you get the answer from the first statement itself then also you have the below two options pending out of which you have to choose one: 

• The data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
• The data either in statement I alone or in statement II alone are sufficient to answer the question.

So, even if you get the answer from the Statement I, you need to check if Statement II is alone sufficient to answer the question and need to answer accordingly.

Combine the Statements & Check their Combination

In case if you are not able to find the answer by either of the statements alone then you will have to look for the answer by combining the two statements.

Don’t Presume Anything

What is there with you actually to answer the question is the information which is being given to you. Don’t presume any information other than this and try solving the problem afresh without presuming any information as it may lead you to an incorrect answer.

Five persons P, Q, R, S and T are sitting in a row facing either north or south. The persons at the extreme end are facing in opposite directions. Not more than two adjacent persons face in same direction. Who among the following is sitting second to the left of Q?

I. S sits second to the left of T, who does not sit at any end. One person sits between Q and R and both face in same direction. R and T are not adjacent to each other. P faces in north direction.

II. One person sits between T and S. P and R sit at the extreme end such that P does not sit adjacent to S.  

a. The data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question

b. 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. The data either in statement I alone or in statement II alone are sufficient to answer the question

d. The data given in both statements I and II together are not sufficient to answer the question

e. The data in both statements I and II together are necessary to answer the question

Answer: d

Solution:

Now, from statement I,

Now, S sits second to the left of T, who does not sit at any end. One person sits between Q and R and both face in same direction. R and T are not adjacent to each other. P faces in north direction. So, the possible arrangements are,

(i).

P(North)

T(South)

Q(South)

S(North)

R(South)

(ii).

R(South)

S(North)

Q(South)

T(North)

P(North)

So, either P or R sits second to the left of Q.

So, statement I alone is not sufficient.

Now, from statement II,

Now, One person sits between T and S. P and R sit at the extreme end such that P does not sit adjacent to S. So, the possible arrangements are,

(i).

P

T

Q

S

R

(ii).

P

S

Q

T

R

So, statement II alone is not sufficient.

By combining both statements I and II, either P or R sits second to the left of Q.

Hence, option d.
