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