The right answer is 11576 beetles.
All you have to do is add 5% to the population in three steps (three years).
5% of 10,000 corresponds to 500, so in the first year the population becomes 10,500.
5% of 10,500 corresponds to 525, so in the second year the population becomes 11025.
5% of 11025 corresponds to 551.25 (rounded to 551), so in the second year the population becomes 11576.
