Three persons A,B, C were sitting in a row of three chairs.When asked about their respective positions, each of them made two statements as follows.It is known that each of them made a true statement and a false statement in any order.

A: I am at te extreme left.

    C is at the extreme right.

B: A is between me and C and myself.

    I am at extreme right.

C: I am at the extreme left.

    B is at the extreme right.

What are the actual positions from left to right?


A) A-B-C

B) C-A-B

C) A-C-B

D) None of these

Answer:

Option C

Explanation:

Assuming the first statement of A as true and second as false, we get

Name I II Position
A T F Extreme left
B F T Extreme right
C F T Middle

If the first statement of A is lie and second is true, then C will be at extreme right and A will be at centre and B will be at the extreme left.But it violates the conditions given by C.

Therefore the arrangement from left to right will be A-C-B.
