Seven people, N, H, C, D, E, R and G, are sitting in a row, facing north. Only one person sits to the left of R. G sits fourth from the right end. Only two people sit between R and E. D sits to the immediate left of N. H does not sit to the left of C. How many people sit between C and D?
Four
Since only one person sits to the left of R, R occupies position 2 from the left end.
G sits fourth from the right end, which is position 4 from the left in a row of seven.
Only two people sit between R (position 2) and E, so E occupies position 5.
D sits to the immediate left of N; among the remaining positions 1, 3, 6 and 7, only 6 and 7 are adjacent, so D takes position 6 and N takes position 7.
The remaining positions 1 and 3 go to H and C. Since H does not sit to the left of C, C must be at position 1 and H at position 3.
The final seating from left to right is C, R, H, G, E, D, N.
Between C (position 1) and D (position 6), the people at positions 2, 3, 4 and 5 sit, which is four people.
Hence, four people sit between C and D.
