Given:

A city's population has increased 40% in the last 5 years and is now 53,782 people.

To find:

The population 5 years ago.

Solution:

Let x be the population 5 years ago.

A city's population has increased 40% in the last 5 years.

So, present population is

x+x* (40)/(100)=x+0.4x=1.4x

It is given that the present population is 53782.

1.4x=53782

x=(53782)/(1.4)

x=38415.7142857

$x\approx 38416$

Therefore, the population 5 years ago was about 38416.
