Seven friends A, B, C, D, E, F and G are sitting in a circle facing the centre. A is between E and D. F is between B and G. B is second to the right of E. G is sitting:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → to the immediate right of F
Note: The given answer is as per the official NTA Answer Key. However, the question has two possible answers, i.e. both Option (2) and Option (3), as explained below.
All seven face the centre, so for each of them the right-hand neighbour is the next seat anticlockwise and the left-hand neighbour the next seat clockwise (seen from above).
B is second to the right of E: B sits two seats anticlockwise from E.
A is between E and D, so A sits next to E. If A sat next to E on the anticlockwise side, D would need the next seat, which is B’s; so A is on E’s clockwise side and D next to A.
F is between B and G. The seat between E and B is the only one left on B’s clockwise side, and G cannot then sit at E’s place; so F is next to B on the anticlockwise side and G next to F.
The last seat, between E and B, is C’s. Going anticlockwise: E, C, B, F, G, D, A.
Option (1) between A and F — Incorrect. G sits between F and D.
Option (2) to the immediate right of F — Correct. The seat next to F anticlockwise, F’s right, is G’s.
Option (3) second to the left of A — Correct. Going clockwise from A (A’s left), the first seat is D’s and the second is G’s.
Option (4) fourth to the left of E — Incorrect. Clockwise from E come A, D, G and then F, so the fourth to E’s left is F.
Tip for students: When a question has two correct answers, mark the answer you worked out yourself. If NTA’s answer key gives the other one, challenge it when NTA opens the window for challenges.
