The population of the town increased by 10% annually if the present population is 22000 find its population a year ago​

Answer»

Given that the PRESENT population of the town is 22000

The population of the town increased by 10%

We have to find the population of the town a year ago

So let the population of town a year ago be 'A'

We will find 110% of x because in order to find percentage INCREASE

(100+x)/100 where x is the percentage increase in population.

A × (100×10)/100 =22000

A × 110/100 = 22000

A= (22000× 100) /110

A= 20000

HENCE the population of the town a year ago was 20000.

Thanks
