Seven friends A, B, C, D, E, F and G sit in a row facing north. C sits at the extreme left end. Exactly three persons sit between C and E. B sits immediately to the right of E. A sits third to the left of G. D is not adjacent to C. Who sits at the extreme right end of the row?

Question

Accepted Answer

G. C is at position 1. Three persons between C and E puts E at position 5, so B (right of E) is at 6. A third to the left of G forces G at 7 and A at 4. D not adjacent to C gives D at 3, F at 2. Order: C, F, D, A, E, B, G. The extreme right end is G.
