present population=24000
increase in one year= 24000×5/100=1200
hence population after one year or a year letter=25200
now let population a year ago be y then
y+5y/100= 24000
105y=24000×100
y=2400000/105=22857.14
increase in one year= 24000×5/100=1200
hence population after one year or a year letter=25200
now let population a year ago be y then
y+5y/100= 24000
105y=24000×100
y=2400000/105=22857.14
