Six persons A, B, C, D, E and F sit in a row facing north. E sits at the extreme right end. F sits second from the left end. B sits immediately to the left of E. D sits at one of the two extreme ends. A sits exactly between F and C, with the three of them sitting next to one another. Who sits third to the left of B?
F sits third to the left of B. The clues fix the order from left to right as D, F, A, C, B, E. B is at position 5, and counting three places to the left gives position 2, which is F.

Explanation
E is at position 6 counted from the left, so B is at 5. F is at 2. D must be at an extreme end, and position 6 is taken, so D is at 1. A, C remain for positions 3 and 4. A is between F (2) and C, so A is at 3 and C is at 4. The order is D, F, A, C, B, E. Third to the left of B (position 5) is position 2, which is F. D is wrong because D is fourth to the left of B.
