Correct answer: C
Final answer: 10000 shoes.
Total inhabitants = 10000.
One-legged people = 5% of 10000 = 500. Each one-legged person needs one shoe.
Remaining people = 10000 − 500 = 9500.
Half of these 9500 go barefoot = 4750 barefoot; the other 4750 need two shoes each.
Total shoes required = 500 × 1 + 4750 × 2 = 500 + 9500 = 10000.
Therefore the least number of shoes needed on the island is 10000.
