Question

Marimar comes from an island-town of 2000 people. She goes to the mainland with a friend and there they catch a highly contagious virus. A week after their return to their island-town, 8 people are infected. How many will be affected after another week?

Answer 1

Given, total number of people in an island-town is 2000. After a week after Marimar and her friend return to their island-town, 8 people are infected.

Mathematically, rate of spreading from two people is 6.

Then, after first week, there are 8 people infected( include marimar and her friend ).

Now, from these 4 infected pair, they infected 6×4=24 people.

Therefore, there are 24 people infected after next week.
