Answer: P sits between R and S.

Question 19

Six persons R, S, T, U, P and Q are sitting in a row. Some are facing North and some are facing South. R sits third from the left end facing North. S sits second to the right of R and faces opposite direction. T sits at the left extreme end facing South. U sits immediately to the left of S facing North. Q sits at the right extreme end. Who sits between T and R?
Solution Approach:

Step 1: Mark directions
↑ = North facing, ↓ = South facing

Step 2: Apply position-based conditions
- R sits third from the left end facing North (↑) → Position 3
- T sits at the left extreme end facing South (↓) → Position 1

Position: T(↓) _ R(↑) _ _ _

Step 3: Apply relative positioning
- S sits second to the right of R (pos 3) → Position 5
- S faces opposite direction to R (North) → S faces South (↓)
- U sits immediately to the left of S (pos 5) facing North (↑) → Position 4

Position: T(↓) _ R(↑) U(↑) S(↓) _

Step 4: Fill remaining positions
Remaining persons: P, Q
Position 2 gets P, Position 6 gets Q

Final Arrangement:
Pos: T(↓) P(↑) R(↑) U(↑) S(↓) Q(↑)

Verification:
✓ R at pos 3, facing North
✓ S at pos 5 (second right of R), facing South (opposite of R)
✓ T at pos 1 (left extreme), facing South
✓ U at pos 4 (immediately left of S), facing North

Person between T (pos 1) and R (pos 3): pos 2 = P

Answer: P sits between T and R.

Question 20

Six persons S, T, R, P, Q and U are sitting in a row. Some are facing North and some are facing South. S sits third from the left end facing North. T sits second to the right of S and faces opposite direction. R sits at the left extreme end facing South. P sits immediately to the left of T facing North. U sits at the right extreme end. Who sits between R and S?
Solution Approach:

Step 1: Mark directions
↑ = North facing, ↓ = South facing

Step 2: Apply position-based conditions
- S sits third from the left end facing North (↑) → Position 3
- R sits at the left extreme end facing South (↓) → Position 1

Position: R(↓) _ S(↑) _ _ _

Step 3: Apply relative positioning
- T sits second to the right of S (pos 3) → Position 5
- T faces opposite direction to S (North) → T faces South (↓)
- P sits immediately to the left of T (pos 5) facing North (↑) → Position 4

Position: R(↓) _ S(↑) P(↑) T(↓) _

Step 4: Fill remaining positions
Remaining persons: Q, U
Position 2 gets Q, Position 6 gets U

Final Arrangement:
Pos: R(↓) Q(↑) S(↑) P(↑) T(↓) U(↑)

Verification:
✓ S at pos 3, facing North
✓ T at pos 5 (second right of S), facing South (opposite of S)
✓ R at pos 1 (left extreme), facing South
✓ P at pos 4 (immediately left of T), facing North

Person between R (pos 1) and S (pos 3): pos 2 = Q

Answer: Q sits between R and S.
