Answer 1

Answer:

Step-by-step explanation:

The rabbit population in community A increases at 25% per year. The rabbit population in community A increases at 25% per year while that in community B increases at 50% per year.

The rabbit population in community A increases at 25% per year while that in community B increases at 50% per year. If the present populations of A and B are equal, what will he the ratio of the number of rabbits in community B to that in community A after 2 years?

A.  1.44

B.  1.72

C.  1.90

D.  1.26

Answer

Let the present population of rabbits in community A and community B be 400.

Community A increases at 25% per year.

So, after one year = 400 + 100 = 500

After two years = 500 + 125 = 625

Community B increases at 50% per year.

So, after one year = 400 + 200 = 600

After two years = 600 + 300 = 900

Ratio = 900/625 = 1.44

The correct option is A.
