The city of Richmond has 1000 more people than Victoria. Victoria has 4 times as many people as Beacon. If Richmond has 3000 people, how many people are there in Beacon?
Let's be accurate as possible and think first.
500
Victoria has 3000 - 1000 = 2000 people.

Beacon has 2000 / 4 = 500 people.

.

Thus, the answer is 500
