Five
Fix the most constrained person (H) first: since only L is to the right of H, H must be at the second position from the right.
Fix the most constrained person (H) first: since only L is to the right of H, H must be at the second position from the right.
Analyze H and L
There are seven people. If 'Only L sits to the right of H', H must be at position 6 (from the left), making L the 7th person. Sequence: _ _ _ _ _ HL.
Place J
Constraint 'Only one person sits between J and H'. Since position 7 is L, J must be at position 4. Sequence: _ _ _ J _ HL.
Place S
Constraint 'Only two people sit between S and J'. Positions 4 and 7 are occupied. S must be at position 1. Sequence: S _ _ J _ HL.
Place D, T, Y
Constraint 'D sits to the right of T but to the left of Y'. Remaining slots are 2, 3, and 5. Thus, T=2, D=3, Y=5. Final arrangement: S T D J Y H L.
B: Two is incorrect as it implies H is at position 5, which violates the constraint that only L is to the right of H. C: Three is incorrect because the logic places H at the 6th position from the left. D: Four is incorrect as the calculated position for H is fixed by the constraint on L.
A is correct because based on the sequence S, T, D, J, Y, H, L, there are exactly five people (S, T, D, J, Y) sitting to the left of H.
When a question says 'Only X sits to the right/left of Y', it immediately identifies Y's absolute position. Use this anchor to build the rest of the row.
