Question

估计 Nisos 人口约为 $6000$ 的年份。

Estimate the year in which the population of Nisos will be approximately $6000.$

$2050$

$2075$

$2100$

$2125$

$2150$

答案：B

知识点：等比数列估算

难度评级：1030

解答：

六千人约为 $1998$ 年人口的 $30$ 倍，因此大约需要人口连续变为原来的 $3$ 倍三次。三次增长需要 $3\cdot 25=75$ 年，也就是从 $1998$ 年起约到 $2073$ 年，因此 $2075$ 最接近。

所以正确答案是 B。

This would be the year the population is $30$ times as much as in $1998.$ This means the population triples approximately $3$ times, making the year approximately $3\cdot 25=75$ years after $1998.$ This would be $2073,$ so $2075$ is the best approximation.

Thus, the correct answer is B .
