Question 1
Six persons P, S, Q, R, T and U are sitting in a row. Some are facing North and some are facing South.
P sits third from the left end facing North. S sits second to the right of P and faces opposite direction.
Q sits at the left extreme end facing South. R sits immediately to the left of S facing North.
U sits at the right extreme end.
Who sits between Q and P?
Solution Approach:
Step 1: Mark directions
↑ = North facing, ↓ = South facing
Step 2: Apply position-based conditions
- P sits third from the left end facing North (↑) → Position 3
- Q sits at the left extreme end facing South (↓) → Position 1
Position: Q(↓) _ P(↑) _ _ _
Step 3: Apply relative positioning
- S sits second to the right of P (pos 3) → Position 5
- S faces opposite direction to P (North) → S faces South (↓)
- R sits immediately to the left of S (pos 5) facing North (↑) → Position 4
Position: Q(↓) _ P(↑) R(↑) S(↓) _
Step 4: Fill remaining positions
Remaining persons: T, U
Position 2 gets T, Position 6 gets U
Final Arrangement:
Pos: Q(↓) T(↑) P(↑) R(↑) S(↓) U(↑)
Verification:
✓ P at pos 3, facing North
✓ S at pos 5 (second right of P), facing South (opposite of P)
✓ Q at pos 1 (left extreme), facing South
✓ R at pos 4 (immediately left of S), facing North
Person between Q (pos 1) and P (pos 3): pos 2 = T
Answer: T sits between Q and P.
Step 1: Mark directions
↑ = North facing, ↓ = South facing
Step 2: Apply position-based conditions
- P sits third from the left end facing North (↑) → Position 3
- Q sits at the left extreme end facing South (↓) → Position 1
Position: Q(↓) _ P(↑) _ _ _
Step 3: Apply relative positioning
- S sits second to the right of P (pos 3) → Position 5
- S faces opposite direction to P (North) → S faces South (↓)
- R sits immediately to the left of S (pos 5) facing North (↑) → Position 4
Position: Q(↓) _ P(↑) R(↑) S(↓) _
Step 4: Fill remaining positions
Remaining persons: T, U
Position 2 gets T, Position 6 gets U
Final Arrangement:
Pos: Q(↓) T(↑) P(↑) R(↑) S(↓) U(↑)
Verification:
✓ P at pos 3, facing North
✓ S at pos 5 (second right of P), facing South (opposite of P)
✓ Q at pos 1 (left extreme), facing South
✓ R at pos 4 (immediately left of S), facing North
Person between Q (pos 1) and P (pos 3): pos 2 = T
Answer: T sits between Q and P.
