Question

the population of a town increased by 8% annually if the present population is 54000 what was it a year ago?

Answer 1

Hi ,

Let the last year population = x

Present year population = 54000

Increased percent = g = 8 %

Present population = last year population × ( 100 + g )/100

54000 = x × ( 100 + 8 ) / 100

54000 = x × ( 108 / 100 )

( 54000 × 100 ) / 108 = x

50000 = x

Therefore,

The last yeat population = x = 50000

I hope this helps you.

Answer 2

Let the last year population = x  

Present year population = 54000

Inreased percent = g = 8 %

Present population = last year population × ( 100 + g )/100

54000 = x × ( 100 + 8 ) / 100

54000 = x × ( 108 / 100 )

( 54000 × 100 ) / 108 = x  

50000 = x

Therefore,

The last yeat population = x = 50000

 hope this helps you.
