Answer:

the original number of people is 25

Step-by-step explanation:

Let "x" be original number of people.

\frac{9000}{x+20} = \frac{9000}{x} - 160

\frac{9000}{x+20} - \frac{9000}{x} = - 160

9000x - 9000(x + 20) = - 160(x)(x + 20)

160x² + 3200x - 180000 = 0

x² + 20x - 1125 = 0

x_{1} = 25 individualsthe original number of people

x_{2} = - 45 not an answer of the task.
