Directions: Each of the following consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question:
A, B, C, D and E stand in a row for a photograph. Who is standing 4th from the left?
Statement I : E is the person standing in the middle.
Statement II : A and B are neighbors of E.
Options
- AIf the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.
- BIf the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question.
- CIf the data either in statement I alone or in statement II alone is sufficient to answer the question.
- DIf the data in both statement I and II together are not sufficient to answer the question.
Correct answer
D.
If the data in both statement I and II together are not sufficient to answer the question.
Step-by-step solution
We have,
A, B, C, D and E stand in a row for a photograph. Who is standing 4th from the left?
Statement I: E is the person standing in the middle.
Statement II: A and B are neighbors of E.
Checking statement I alone:
Statement I: E is the person standing in the middle.
References:
E is the person standing in the middle.
Inferences:
In this statement, there is no information about all the persons standing for the photograph.
Clearly, data in statement I alone are not sufficient to reach the answer.
Checking statement II alone:
Statement II: A and B are neighbors of E.
References:
A and B are neighbors of E.
Inferences:
In this statement, there is no information about where C and D are standing.
Clearly, data in statement II alone are not sufficient to reach the answer.
Checking both statements I and II together:
Statement I: E is the person standing in the middle.
Statement II: A and B are neighbors of E.
References:
E is the person standing in the middle.
A and B are neighbors of E.
Inferences:
After using the above references, we have:
E is standing third from both left and right side. And, A and B are neighbors of E but definite positions of A and B is not known. So, we cannot answer the question.
Clearly, data in both statements I and II together are not sufficient to reach the answer.
Option D is hence the correct answer.
A, B, C, D and E stand in a row for a photograph. Who is standing 4th from the left?
Statement I: E is the person standing in the middle.
Statement II: A and B are neighbors of E.
Checking statement I alone:
Statement I: E is the person standing in the middle.
References:
E is the person standing in the middle.
Inferences:
In this statement, there is no information about all the persons standing for the photograph.
Clearly, data in statement I alone are not sufficient to reach the answer.
Checking statement II alone:
Statement II: A and B are neighbors of E.
References:
A and B are neighbors of E.
Inferences:
In this statement, there is no information about where C and D are standing.
Clearly, data in statement II alone are not sufficient to reach the answer.
Checking both statements I and II together:
Statement I: E is the person standing in the middle.
Statement II: A and B are neighbors of E.
References:
E is the person standing in the middle.
A and B are neighbors of E.
Inferences:
After using the above references, we have:
E is standing third from both left and right side. And, A and B are neighbors of E but definite positions of A and B is not known. So, we cannot answer the question.
Clearly, data in both statements I and II together are not sufficient to reach the answer.
Option D is hence the correct answer.
