In a hall there are 6 rows of chairs, all facing the stage. Six students, A, B, C, E, F and G, sit one behind the other, one in each row.
A sits behind F but in front of E. F sits behind B. G sits in front of B. C sits behind E.
What is the order in which they sit from the first row (nearest the stage) to the last?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → GBFAEC
Each statement tells who is ahead of whom. Joining the statements into one chain from the front row to the back row gives the order.
A is behind F and in front of E, so from the front the order is F, A, E
F is behind B, so B comes ahead of F: B, F, A, E
G is in front of B, so G comes first: G, B, F, A, E
C is behind E, who is last in the chain, so C sits in the last row: G, B, F, A, E, C
All six students are now in one chain, so the order from the first row is GBFAEC
