Question

the population of a town increases 8% annually if its present population is 14 2560 what was it a year ago​

Answer 1

Answer:

Given,present population =142560

population increases 8% annually

Step-by-step explanation:

let the population of previous year be x

then,x+8% of x=142560

or x=142560-8% of x

orx=142560-8x/100

or x=(14256000-8x)/100

or 100x =14256000-8x

or 100x+8x =14256000

or 108x=14256000

or x=14256000/108

or x=132000

so, previous year population was 132000
