Data Sufficiency

[paresh_patil]

Is the statement sufficient?

A group of rabbits multiplies at a constant rate. By
what factor does its population increase every day?

(1) The population grows from 200 to 5,000 in one
week.

Hi Paresh,

I hope you are well. That statement does looks sufficient.

We can set up a chart to illustrate the population growth. Each day the population grows at a constant rate. Let's call that X.

Day Population
1 200
2 200x
3 200x^2
4 200x^3
5 200x^4
6 200x^5
7 200x^6 or 5,000 (according the statement)

So you can solve 200x^6 = 500. The resulting number will be the factor by which the rabbit population multiplies on a daily basis.

Making charts like the one above is VERY helpful on the GMAT for all sorts of questions.

I hope that his helps and let me know if you need more advice on this subject.

HG.

hey thank you. And thank you for the chart idea.

Will get back with more difficulties.
