Question: Five persons - A, B, C, D and E are sitting in a row. Who is sitting in the middle?

Statements:

  1. B is between E and C.
  2. B is to the right of E.
  3. D is between A and E.

[A]. Only I and II
[B]. Only II and III
[C]. Only I and III
[D]. All I, II and III
[E]. None of these

Answer: Option D

Explanation:

From I, the order is : E, B, C or C, B, E.

From II, the order is : E, B.

From III, the order is : A, D, E.

Combining the above three, we get the order as : A, D, E, B, C. Clearly, E is sitting in the middle.

2nd option does not matter,, the answer has to be 'E' whether the order is -"A D -E- B C" or "C B -E- D A"

So the answer should be [C]ONLY I AND III.

I have to find middle position. We can get middle position from I And III but not correct sequence of sitting arrangement but you can correct position of middle. Check it once.

From I, the order is : E, B, C or C, B, E.

From II, the order is : E, B.

From III, the order is : A, D, E (or the order can be E, D, A as well).

Combining I and III, we get two possible orders as:A, D, E, B, C and C, B, E, A, D.

Clearly, in both, E is seated in the middle, irrespective of whether E is seated to the right or left of B.

So the correct option should be "option [C]".

The third option says D is between A and E, which leaves us with two possibilities, ADE or EAD. So, even by combining all three statements the possibilities of sitting arrangements are ADEBC and EBCDA. So according to me, option [E] should be the correct answer.

By using 1 we can say that option is.
E B C or C B E.

By using 3 (without seeing 2).
We can say that it is.
A D E B C or C B E D A.

FROM USING 1 AND 2 WE CAN BE SURE THAT 'E' IS IN MIDDLE.

So, option C is correct.
