The correct option is B (b) 324138
Total number of migrants = 35% of 728400=254940 ……………………………….(i)
Total number of locals= 473460 --------------------------------------(ii)
Total number of rural in (i) = 20% of 254940= 50988 --------------------------------------(iii)
Total number of urban in (i) = 80% of 254940=203952 ---------------------------------------(iv)
Number of females in (ii)= 48% of 473460=227260.8 ---------------------------------------(v)
Number of females in (iii)= 30% of 50988 =15296.4 ---------------------------------------(vi)
Number of females in (iii)= 40% of 203952=81580.8 --------------------------------------(vii)
Total number of females in the city
= (v) + (vi) + (vii) = 324138.
(b) 324138
