Correct answer: A
Answer: The share of each remaining person increased by 1/7 of the original share.
Original share per person = 1/8 of the total cost.
New share per person (after one withdraws) = 1/7 of the total cost.
Absolute increase = 1/7 − 1/8 = 1/56.
Increase as a fraction of the original share = (1/56) ÷ (1/8) = (1/56) × 8 = 1/7.
Therefore the share of each remaining person increased by 1/7 of their original share.
