Question

the population of a city increase each year 5%. what was its population in 1990if its population was 185220 in 1993​

Answer 1

Answer:

Step-by-step explguess it's 18549

Answer 2

Answer:

we know, population increases each year by 5%

then number of years from 1990-1993= 3 years

percentage increase in 3 years = 3x5= 15%

now, by decreasing the population by 15% out of 185220,we will get population in 1990.

so,185220x15/100                           (finding 15% of the population)

=27783

therefore decreasing,

185220-27783=157437

so the population in 1990 is  157437

hope this helps...
