Directions: The below mentioned question is to be answered using...
Directions: The below mentioned question is to be answered using the statements I and II given below. You have to determine the statement(s) which is/are sufficient to answer the question and mark the option accordingly.
8 persons viz. B,D,K,F,H,J,L and N are standing in a linear row facing towards the north. What is the position of H from the right end, if number of persons between H and E are 2?
Statement I : F is second to the left of G, who is on the immediate right of H. No person stands between J and B. B is second to the left of E.
Statement II : E is third to the right of B. J is not an immediate neighbor of L. F and L are not adjacent. H is on the immediate right of F.
Options
- AIf the data in statement I alone is sufficient to answer the question
- BIf the data in statement II alone is sufficient to answer the question
- CIf the data in statements I and II is necessary to answer the question
- DIf the data in statements I and II is not sufficient to answer the question
Correct answer
D.
If the data in statements I and II is not sufficient to answer the question
Step-by-step solution
Checking statement I:
Statement I: F is second to the left of G, who is on the immediate right of H. No person stands between J and B. B is second to the left of E.
Case-1
Statement I: F is second to the left of G, who is on the immediate right of H. No person stands between J and B. B is second to the left of E.
Case-1
| Persons | J/ | B | J/ | E | F | H | G |
Case-2
| Persons | B | J | E | F | H | G |
Thus we cannot determine whether H is third or second from right end.
Hence data in statement I is not sufficient.
Checking statement II:
Statement II: E is third to the right of B. J is not an immediate neighbor of L. F and L are not adjacent. H is on the immediate right of F.
Case-1
| Persons | B | E | F | H |
Case-2
| Persons | B | E | F | H |
Thus we cannot determine whether H is first or second from right end.
Hence data in statement II is not sufficient.
Checking both the statements:
Hints “E is third to the right of B” and “B is second to the left of E” clash with each other , thus asingle arrangement cannot be obtained using both the statements.
Hence data in neither statement I nor statement II is sufficient.
Hence option D is correct.
