Seven girls, A, B, C, D, E, F and G, sit in a row facing North. A sits fifth to the right of C. C does not sit at either end of the row. D sits in the middle of the row. E sits third to the left of F. Only three girls sit between B and G. G is not an immediate neighbour of C.
Who sits to the immediate right of G?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → F
Number the seats 1 to 7 from the left. A gap of five seats leaves only a few places for C and A, so fix them first.
A is fifth to the right of C, so (C, A) is (1, 6) or (2, 7); C is not at an end, so C is in seat 2 and A in seat 7
D is in the middle, seat 4
E is third to the left of F: the pairs (1, 4), (2, 5) and (4, 7) use a taken seat, so E is in seat 3 and F in seat 6
Seats 1 and 5 are left for B and G, with three girls (seats 2, 3, 4) between them
G is not next to C, so G is not in seat 1; G is in seat 5 and B in seat 1
The row is B, C, E, D, G, F, A, so the girl to the immediate right of G is F
