Five friends A, B, C, D and E are sitting in a straight row, facing north. A is not at the exact centre position of the row. C is second from one extreme end, while fourth from the other extreme end. B and D sit at the extreme ends of the row. Who sits at the exact centre position of the row?

AD

BE

CA

DC

Answer:

B. E

Read Explanation:

  • Correct Answer : Option E

  • To find the exact centre seat among 5 friends sitting in a straight row, first note a key fact:

Important fact:

  • In a row of 5 people, the exact centre position is the 3rd seat (since positions go 1,2,3,4,5).

Now apply the given conditions:

  • B and D are at the extreme ends ⇒ they must be at positions 1 and 5 (in some order).

  • C is second from one end and fourth from the other end.

    • If C is second from the left, C = position 2.

    • If C is second from the right, C = position 4.
      But the statement says C is simultaneously second from one end and fourth from the other end—this exactly matches position 2 or 4.

  • That means C cannot be at position 3.

  • The remaining unoccupied seat (after placing B, D, and C) must be the centre seat (position 3).

  • After assigning extremes to B and D and placing C at position 2 or 4, the only person left to occupy the centre (position 3) is E.

  • Therefore, E sits at the exact centre position of the row.
