(b) 349680
(c) 509940
(d) None

• 896660
  explanation :
  Migrants = 35 % of 728400 = (35x/100 * 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 * 473460 + 30/100 * 94692 + 40/100 * 160248)
  = 227260.8 + 28407.6 + 64099.2 = 896660
