3
Take the seven seats from left to right as positions 1 to 7 (all facing north).
Only two people sit to the left of G, so G is at position 3.
Only three people sit between G (position 3) and C, so C is at position 7.
Only one person sits between C (position 7) and E, so E is at position 5.
A sits to the immediate left of B, and the only adjacent empty pair left of G is positions 1 and 2, so A is at position 1 and B at position 2.
The remaining seats are positions 4 and 6 for D and F. Since F is not an immediate neighbour of C (position 7), F cannot be at position 6, so F is at position 4 and D at position 6.
The final order is A, B, G, F, E, D, C. To the right of F (position 4) sit E, D and C.
Hence, 3 people sit to the right of F.
