Answer 2

Answer:

1500000

Step-by-step explanation:

Let the population of the city 5 yrs ago be 'x'.

A/Q, Population increase in 5 yrs=20%

Population after 5 yrs=1800000

i.e. x + 20% of x =1800000

=> x + 20x/100 = 1800000

=> x +x/5 = 1800000

=> 6x/5=1800000

=> 6x = 9000000

=> x=1500000

Therefore, the population of the city 5 yrs ago was 1500000.
