Nine persons, A, B, C, D, E, F, G, H and I, are watching a movie in a theatre, sitting in a row facing North. B is at one end of the row. H is seated next to both F and G. C is to the immediate right of D and third to the right of E. A is to the immediate left of F. F is third to the left of B. Apart from B, who is at an end of the row?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → E
Number the seats 1 to 9 from the left and first decide which end B is at.
F is third to the left of B, so B cannot be in seat 1; B is in seat 9 and F in seat 6
A is to the immediate left of F, so A is in seat 5
H is next to F and G; seat 5 is A’s, so H is in seat 7 and G in seat 8
Seats 1 to 4 are left for C, D, E and I
C is third to the right of E, so (E, C) is (1, 4); D, to the immediate left of C, is in seat 3
I takes seat 2
The row is E, I, D, C, A, F, H, G, B, so the two ends are E and B
