Statement-1: B is sitting opposite to C and D is sitting opposite to E.
Statement-2 : F is sitting on the immediate left of B.
Which one of the following is correct in respect of the Question and the Statements?
a. Statement-1 alone is sufficient to answer the Question
b. Statement-2 alone is sufficient to answer the Question
c. Both Statement-1 and Statement-2 are sufficient to answer the Question
d. Both Statement-1 and Statement-2 are not sufficient to answer the Question
Correct Answer: d. Both Statement-1 and Statement-2 are not sufficient to answer the Question
Question from UPSC Prelims 2022 CSAT Paper
Explanation :
To determine who is sitting on the immediate left of A, we need to analyze the given statements.
Statement-1: B is sitting opposite to C and D is sitting opposite to E.
From this statement, we can deduce the following seating arrangement (clockwise):
B is opposite to C.
D is opposite to E.
However, this statement does not provide any information about the position of A or who is sitting on the immediate left of A. So, Statement-1 alone is not sufficient to answer the question.
Statement-2: F is sitting on the immediate left of B.
This statement gives us information about the position of F in relation to B, but it does not provide any information about the position of A. So, Statement-2 alone is not sufficient to answer the question.
Combining Statement-1 and Statement-2:
We know the following:
B is opposite to C.
D is opposite to E.
F is sitting on the immediate left of B.
However, even after combining both statements, we still do not have enough information to determine who is sitting on the immediate left of A.
Thus, the correct answer is:
d. Both Statement-1 and Statement-2 are not sufficient to answer the Question.
