Question
Six persons (D, E, F, G, H, and I) are sitting in a
straight row facing north. G sits second to the left of I. One person sits between G and D. F sits second to the right of H. D doesn’t sit at extreme end of row. E doesn’t sit adjacent to G. How many persons sit between H and I?Solution
G sits second to the left of I. One person sits between G and D. D doesn’t sit at extreme end of row. D ____ G ____ I F sits second to the right of H. E doesn’t sit adjacent to G. E  D   H   G    F   I Final arrangement as shown below: E        D        H        G        F         I
