Seven girls G1, G2, G3, G4, G5, G6 and G7 are sitting around a circular table facing the centre (not necessarily in the same order). G6 is second to the left of G1. G7 is second to the left of G6. G5 is third to the right of G2. G5 is not the immediate neighbour of G6. G4 is third to the right of G3. Who is second to the left of G7?

G3

Answer: G3

In this question you need to first place G1 and then place G6. Then place G7 second to the left of G6. G5 is not the immediate neighbour of G6, so we can place G5 to the immediate left of G7 and place G2 accordingly.
