Answer 1

The former population of the city is 719417 .

Explanation:

As given

After a 3% increase, the population of a city is 741000.

Let us assume that the former population is 100% .

As the current population is increase by 3% .

Thus

Current population percentage = 100 % + 3%

= 103 %

`Former\ population = (100* Current\ population)/(103)`

`Former\ population = (100* 741000)/(103)`

`Former\ population = (74100000)/(103)`

Former population = 719417 (Approx)

Therefore the former population of the city is 719417 .

Answer 2

After a 3% increase----------------the population of a city is 741000

X=the former population

741000=1.03*X
X=741000/1.03
X=719417
the former population was 719417
