Twelve friends are sitting in two parallel lines. There are 6 people sitting in each row and facing a person of the other row. In row 1, A, B, C, D, E and F are seated and all of them are facing north. In row 2, O, P, Q, R, S and T are seated and all of them are facing south but not necessarily in the same order. C, is third to the right of B. C is not an immediate neighbour to either E or A. P is third to the left of S. Neither P nor S are sitting at the extreme ends of any row. F, faces O, who is second to the right of T, and T is not an immediate neighbour to S. Only two people are sitting between Q and T. A, is not facing R. Which of the following pairs could be sitting at the extreme ends?
RE, TC
Given:
- 6 people sitting in each row and facing a person of the other row.
- In row 1, A, B, C, D, E and F are seated and all of them are facing north.
- In row 2, O, P, Q, R, S and T are seated and all of them are facing south.
1) P is third to the left of S. Neither P nor S are sitting at the extreme ends of any row.
2) F, facesO, whois second to the right of T, and T is not an immediate neighbour to S.
Here, O is second to the right of T.
3) Only two people are sitting between Q and T.
4) C, is third to the right of B. C is not an immediate neighbour to either E or A.
5) A, is not facing R.
Here two cases are possible:
Case 1:
Case 2:
So from the both cases 'RE' and 'TC or TD' pairs are sitting at the extreme ends but TD pair is not given in any options.
Thus we will take pairs of "RE' and 'TC".
Hence, 'RE' and 'TC' pairs are sitting at the extreme ends
