38,500

Step-by-step explanation:

162/3% = (16 2/3) / 100 = (50/3) / 100 = 50/300 = 1/6

1/6 of the original population was ...

1/6 * 30,000 = 5,000

So the population at the end of 1990 was

30,000 + 5,000 = 35,000.

In 1991, 10% of that number was added, so the population at the end of 1991 was ...

35,000 + 0.10*35,000 = 38,500
