Question

the population in a city increases by 8 percent if the present population is 14,25,600 .what was the population in last year?​

Answer 1

Answer:

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 year population = x = 50000

Present population =100x(100+increaseinpopulation)

where x is population last year

∴142560=100x(100+8)

⇒x=132000
