In a city ,35% of the population is composed of migrants ,20% of whom are from rural areas. Of the local
population, 48% is female while this figure for rural and urban migrants is 30% and 40 % respectively. If the
total population of the city is 728400. what is its female population ?
Migrants = 35% of 728400 = `((35x)/(100) xx 728400)` = 254940.
Local population = (728400 - 254940) = 473460
Rural population = 20% of 473460 = 94692
Urban population = 254940 - 94692 = 160248
`:.` Female population = 48% of 473460 + 30% of 94692 + 40% of 160248
= `(48/100 xx 473460 + 30/100 xx 94692 + 40/100 xx 160248)`
= 227260.8 + 28407.6 + 64099.2 = 896660
