Seven people, W, X, Y, Z, E, F and G, are sitting in a row, facing north. Only two people sit to the right of Y. Only two people sit between Y and F. Only two people sit between E and W. W sits to the immediate left of Y. Z sits to the immediate right of X. Who sits at the third position from the left end of the row?
W
Z
Y
G
G
Start by placing the fixed anchor (Y has exactly two to the right) and build outwards using the immediate neighbors (W is left of Y, Z/X pair).
Start by placing the fixed anchor (Y has exactly two to the right) and build outwards using the immediate neighbors (W is left of Y, Z/X pair).
Establish the base positions
There are 7 positions. Only two people sit to the right of Y, meaning Y is at position 5 ( _ _ _ _ Y _ _ ).
Place immediate neighbors
W sits to the immediate left of Y, so W is at position 4 ( _ _ _ WY _ _ ). Only two people sit between Y and F, so F must be at position 2 ( _ F _ WY _ _ ).
Place remaining blocks
Only two people sit between E and W. Since W is at position 4, E can be at position 1 or 7. If E is at 7, then positions 1, 3, and 6 remain for X, Z, and G. Z is to the immediate right of X, requiring two adjacent slots. Only 1 and 3 are left, which are not adjacent. Thus, E must be at position 1. This leaves positions 3, 6, and 7 for X, Z, and G. Placing Z to the right of X makes them 6 and 7. Thus, G must be at position 3.
A: W is at position 4, not 3. B: Z is at position 6, not 3. C: Y is at position 5, not 3.
D is correct because based on the deductions, the arrangement is E(1), F(2), G(3), W(4), Y(5), X(6), Z(7), placing G at the third position.
When solving seating arrangement puzzles, always look for the most restrictive clue first (e.g., 'only two people to the right') to fix your anchor point quickly.
