Step-by-step explanation:

To calculate concentration ratio,

CR4 = (X1 + X2 + X3 + X4) / T

In this equation:

X is the total sales of an individual company (sales figures for the four largest firms are used in the four-firm concentration ratio)

T is the total sales of the industry or market in question.

From the question, T was given as 2000, but individual sales of this companies were not given.

We have

CR4 = (A+B+C+D) / 2000

I believe the information provided in the question is not sufficient to determining percentage of the total output the four firms are responsible for.
