Nine persons, P, Q, R, S, E, U, V, W and X, are watching a movie in a theatre, sitting in a row facing North. X is at one end of the row. W is seated next to both X and V. U is to the immediate right of V and third to the left of E. S is to the immediate left of E. E is second to the left of R. Q is to the immediate right of E. Apart from X, who is at an end of the row?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → R
Facing North, the left end of the row is on the west side. Number the seats 1 to 9 from the left and first decide which end X is at.
W is next to X and V, so X, W and V sit side by side, with W in the middle
If X were in seat 9, W would be in seat 8 and V in seat 7; U, to the immediate right of V, would need seat 8, which W already has. So X is in seat 1
Then W is in seat 2, V in seat 3 and U in seat 4
U is third to the left of E, so E is in seat 7
S is to the immediate left of E (seat 6) and Q to the immediate right of E (seat 8)
E is second to the left of R, so R is in seat 9
P takes the last free seat, seat 5
The row is X, W, V, U, P, S, E, Q, R, so the two ends are X and R
