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 questions.
Seven persons from P to V sit in a linear row facing towards the south. Find the position of U with respect to Q?
Statement I:& U and P sit at a gap of 3 persons and neither of them sits at an extreme end. R is on the immediate right of U. P is on the immediate left of S, who is at a gap of two persons from Q.
Statement II:& Q is third to the right of V, who sits at one of the extreme ends. Neither S nor P is an immediate neighbor of V. R sits adjacent to Q but not to W.
Statement I:& U and P sit at a gap of 3 persons and neither of them sits at an extreme end. R is on the immediate right of U. P is on the immediate left of S, who is at a gap of two persons from Q.
Statement II:& Q is third to the right of V, who sits at one of the extreme ends. Neither S nor P is an immediate neighbor of V. R sits adjacent to Q but not to W.
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
A.
If 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.
Step-by-step solution
Seven persons from P to V sit in a linear row facing towards the south.
Find the position of U with respect to Q?
Statement I: U and P sit at a gap of 3 persons and neither of them sits at an extreme end. R is on the immediate right of U. P is on the immediate left of S, who is at a gap of two persons from Q.
Statement II: Q is third to the right of V, who sits at one of the extreme ends. Neither S nor P is an immediate neighbor of V. R sits adjacent to Q but not to W.
Checking statement I:
All the persons face towards south.
Clearly, U is second to the left of Q.
Hence data in statement I is sufficient to answer the question.
Checking statement II:
All the persons face towards south.
Case-1
Case-2
But in both the cases we are unable to locate U.
Hence data in statement II is not sufficient to answer the question.
Hence option A is correct.
Find the position of U with respect to Q?
Statement I: U and P sit at a gap of 3 persons and neither of them sits at an extreme end. R is on the immediate right of U. P is on the immediate left of S, who is at a gap of two persons from Q.
Statement II: Q is third to the right of V, who sits at one of the extreme ends. Neither S nor P is an immediate neighbor of V. R sits adjacent to Q but not to W.
Checking statement I:
All the persons face towards south.
| S | P | Q | R | U |
Clearly, U is second to the left of Q.
Hence data in statement I is sufficient to answer the question.
Checking statement II:
All the persons face towards south.
Case-1
| Q | R | V |
Case-2
| R | Q | V |
But in both the cases we are unable to locate U.
Hence data in statement II is not sufficient to answer the question.
Hence option A is correct.
